What Is Web Scraping? | Scraper Tools and Bots

Web scraping extracts valuable and often personal data from websites, web applications, and APIs, using either scraper tools or bots that crawl the web looking for data to capture. Once extracted, data can be used for either good or bad purposes. In this article, we’ll take a closer look at web scraping and the risks that malicious web scraping poses for your business. We’ll compare scraper tools and bots, look at detailed examples of malicious web scraping activities, and explain how to protect yourself against malicious web scraping.

What Is Web Scraping?

Web scraping is a type of data scraping that extracts data from websites using scraper tools and bots. It is also called website scraping, web content scraping, web harvesting, web data extraction, or web data mining. Web scraping can be performed either manually or via automation, or using a hybrid of the two.

Data—including text, images, video, and structured data (like tables)—can be extracted via web scraping. Such data can, with varying levels of difficulty, be scraped from any kind of website, including static and dynamic websites. The extracted data is then exported as structured data.

When used ethically, like for news or content aggregation, market research, or weather forecasting, web scraping can be beneficial. However, it can be malicious when used for harmful purposes, like price scraping and content scraping (more on these uses later.)

How Does Web Scraping Work?

Web scraping is carried out using a scraper tool or bot, and the basic process is the same for both:

  1. A person or bad actor deploys a scraper tool on a target website, or installs a bot.
  2. The scraper tool or bot sends automated requests to the website’s server requesting page-specific HTML code.
  3. The server responds with the HTML code as requested.
  4. The scraper tool or bot parses the supplied HTML code and extracts data—including databases—according to user-specific parameters.
  5. The scraper tool or bot then stores the extracted data in a structured format, such as a JSON or CSV file, for later use.

There are three scraping techniques: automated, manual, and hybrid. Manual scraping is the process of extracting data from websites manually, typically by copying and pasting or using web scraping tools that require human intervention. Automated scraping involves using software tools to extract data automatically from websites. Hybrid scraping combines both manual and automated techniques: manual methods are used to handle complex or dynamic elements of a website; automation is used for repetitive and simple tasks.

What Are Scraper Tools and Bots?

Scraper tools and bots are software programs designed to automatically extract data from websites by navigating through web pages and collecting the desired information. Scraper tools and bots can both facilitate large-scale, high-speed web scraping. They are easily confused because they can serve the same purpose—in this case, web scraping. However, scraper tools and bots are actually two different things.

Scraper tools are tools specifically developed for web scraping purposes. Bots are general-purpose software that can be designed to perform a variety of automated tasks, including web scraping. Let’s take a look at each in turn.

What Are Scraper Tools?

Scraper tools, also known as web scrapers, are programs, software, or pieces of code designed specifically to scrape or extract data. They feature a user interface and are typically built using programming languages such as Python, Ruby, Node.js, Golang, PHP, or Perl.

There are four classes of scraper tools:

  • Open-source/pre-built web scrapers (e.g., BeautifulSoup, Scrapy)
  • Off-the-shelf web scrapers (e.g., Import.io, ParseHub)
  • Cloud web scrapers (e.g., Apify, ScrapingBee)
  • Browser extension web scrapers (e.g., WebScraper.io, DataMiner)

As these tool classes suggest, scraper tools can be run as desktop applications or on a cloud server. They can be deployed using headless browsers, proxy servers, and mobile applications. Most options are free and do not require any coding or programming knowledge, making them easily accessible.

Scraper tools can also be categorized by their use case:

  • Search engine scrapers (e.g., Google Search API, SERP API, Scrapebox)
  • Social media scrapers (e.g., ScrapeStorm, PhantomBuster, Sociality.io)
  • Image scrapers (e.g., Image Scraper, Google Images Download, Bing Image Search API)
  • Ecommerce scrapers (e.g., Price2Spy, SellerSprite, Import.io)
  • Video scrapers (e.g., YouTube Data API, Vimeo API, Dailymotion API)
  • Web scraping frameworks or libraries (e.g., BeautifulSoup, Scrapy, Puppeteer)
  • Music lyrics scrapers (e.g., LyricsGenius, Lyric-Scraper)

What Are Bots?

Unlike scraper tools that are specifically designed for web scraping, bots or robots are software/programs that can automate a wide range of tasks. They can gather weather updates, automate social media updates, generate content, process transactions—and also perform web scraping. Bots can be good or bad. Check out our article on good and bad bots and how to manage them for more information.

Bots don’t have a user interface, and are typically written in popular programming languages like Python, Java, C++, Lisp, Clojure, or PHP. Some bots can automate web scraping at scale and simultaneously cover their tracks by using different techniques like rotating proxies and CAPTCHA solving. Highly sophisticated bots can even scrape dynamic websites. Evidently, bots are powerful tools, whether for good or for bad.

Examples of good bots include:

  • Chatbots (e.g., Facebook Messenger, ChatGPT)
  • Voice bots (e.g., Siri, Alexa)
  • Aggregators or news bots (e.g., Google News, AP News)
  • Ecommerce bots (e.g., Keepa, Rakuten Slice)
  • Search engine crawlers (e.g., Googlebot, Bingbot)
  • Site monitoring bots (e.g., Uptime Robot, Pingdom)
  • Social media crawlers (e.g., Facebook crawler, Pinterest crawler)

Examples of bad bots include:

  • Content scrapers (more on these later)
  • Spam bots (e.g., email spam bots, comment spam bots, forum spam bots)
  • Account takeover bots (e.g., SentryMBA [credential stuffing], Medusa [brute-force bot], Spyrix Keylogger [credential harvesting bots])
  • Social media bots (e.g., bot followers, Like/Retweet bots, political bot squads)
  • Click fraud bots (e.g., Hummingbad, 3ve/Methuselah, Methbot)
  • DDoS bots (e.g., Reaper/IoTroop, LizardStresser, XOR DDoS)

Comparison of Scraper Tools vs Bots

Scraper tools and bots can both perform web scraping, but have important differences. Let’s check out the differences between scraper tools and bots.

What Is Malicious Web Scraping?

Malicious web scraping refers to any undesirable, unauthorized, or illegal use of web scraping. Examples include:

  • Any unauthorized web scraping
  • Web scraping that violates terms of service
  • Web scraping that is used to facilitate other types of malicious attacks
  • Any activity that causes severe negative effects to a server or service, including the one being scraped

This table will help you to determine if a particular web scraping activity is benign or malicious.

CriteriaConsiderationBenign web scrapingMalicious web scraping
AuthorizationWas approval granted before web scraping?YesNo
IntentWhat was the original purpose for this web scraping?GoodBad
ApproachHow was the web scraping carried out?Ethically, harmlessUnethically, harmful
ImpactWhat was the impact of the web scraping approach on the scraped server or site?None/slightSevere

Sometimes, even with authorization and good intent, the approach to carrying out web scraping may be inappropriate, resulting in a severe impact on the server or services being scraped.

Examples of Malicious Web Scraping

Malicious web scraping can seriously harm any business. It is important to know what to look out for so you can identify any cases of web scraping that could negatively affect your business. Here are some examples of malicious web scraping activities.

TypeActivityIntent
Social media user profile scrapingScraping social media platforms to extract user profiles or personal informationTargeted advertising, identity profiling, identity theft
Healthcare data extractionScraping healthcare provider websites to access patient records, SSN, and medical informationIdentity theft, blackmail, credit card fraud

Automated account creationCreating fake user accounts using web scraping techniques and credential stuffingSpamming, account fraud, social engineering
Price scrapingScraping ecommerce websites to gather pricing informationUndercutting competitors, scalping, anti-competitive practices

Malicious web scraping can have significant negative impacts on websites and businesses. It can lead to server overload, website downtime and outage, lost revenue, damaged reputation, and legal action, as in the case of Regal Health in 2023.

What Is Price Scraping?

Price scraping is a prime example of malicious web scraping, in which pricing information is harvested from a site—for instance, an ecommerce site, travel portal, or ticketing agency. This is usually done to undercut the competition and gain an unfair price advantage.

How Price Scraping Impacts Businesses

There are several ways that price scraping can harm businesses:

  1. Unscrupulous competitors deploy price scraping bots to monitor and extract real-time pricing and inventory data from the competition. This puts pressure on servers and can lead to service disruption or website outage, resulting in poor user experience, cart abandonment, and non-conversion. Crashes caused by price scraping may account for up to 13% of abandoned carts.
  2. If customers already visited your competitor’s sites, retargeting ads can offer them the same products, redirecting your customers to your competitor’s site.
  3. Competitors who scrape pricing information can lure buyers by setting their own prices lower than yours in a marketplace. They will then rank higher on price comparison websites.
  4. Competitors can use price-scraped data for scalping. Scalping is the practice of buying large quantities of a popular product—often through automated systems or bots—and reselling them at a higher price.
  5. Scraper bots can pull data from hidden but unsecured databases, like customer and email lists. If your customer list and email list are scraped, your customers can end up becoming targets of coordinated malicious attacks or direct advertising from your competitors.
  6. Scraped data can be used to create a knock-off, replica, or spoofing site with a similar name e.g., www.aliexpresss.com for www.aliexpress.com (this is called typosquatting.) The spoofing site can then be used for phishing, for example by capturing and stealing the login credentials of unsuspecting buyers who mistakenly enter the wrong URL.
  7. Spoofing sites can be used to steal credit card information from users who complete checkout. But these customers will either never get what they paid for, or instead receive a knock-off, low-quality version. This can damage seller credibility and reputation, generate negative reviews, and land your website in the Ripoff Report.

Some of the most spoofed brands include (in no particular order):

  • LinkedIn
  • DHL
  • FedEx
  • PayPal
  • Google
  1. A spoofing site impersonating your brand, armed with your pricing and product data, can field exorbitant prices and generate fake negative reviews. They can even flood the fake site with other malicious content to discredit your brand and misinform potential customers.

What Is Content Scraping?

Let’s look at another form of malicious web scraping. Content scraping is a form of web scraping where content is extracted from websites using specialized scraper tools and bots. For example, a website’s entire blog can be scraped and republished elsewhere without attribution or without using rel=canonical or noindex tags.

Examples of abusive scraping include:

  • Copying and republishing content from other sites, without adding original content or value or citing the original source
  • Copying content from other sites, slightly modifying it, and republishing it without attribution
  • Reproducing content feeds from other sites
  • Embedding or compiling content from other sites

How Content Scraping Impacts Businesses

There are several ways that content scraping can harm businesses:

  1. Your content can be copy-pasted verbatim without credit, meaning that the scraper site takes credit for your hard work.
  2. Your entire website(s) could be cloned using content scraping techniques, which can be used maliciously to spoof users for phishing.
  3. Your customers into giving away personal information like credit card details or social security numbers (SSN) via typosquatting. This method was used by convicted felon, Hushpuppi, who engaged in widespread cyber fraud and business email compromise schemes.
  4. If your website is spoofed, fake bot traffic could commit click fraud and ad fraud. This strategy can make it look like your business itself is engaged in click or ad fraud.
  5. Your SEO rankings could be damaged if content scraping makes you compete for visibility and organic traffic against your own duplicate content. If you’re outranked by duplicate content, you may lose revenue to criminals profiting from your hard work. Google does countermeasures in place, but they are not 100% guaranteed.
  6. If content scraping on your website or online assets results in a data breach, you risk facing a class action lawsuit, paying damages, and losing hard-earned customer trust and loyalty.

How to Protect Against Web Scraping

To protect your website against web scraping, you can implement a number of robust security measures. We can sort these techniques into two categories: DIY and advanced. On the DIY end, you might already be familiar with CAPTCHA, rate limiting (limiting the number of requests a user can send to your server in a given time period), and user behavior analysis to detect and block suspicious activities.

More advanced techniques include server-side techniques such as regularly changing HTML structures, hiding or encrypting certain data, and ensuring you have a strong, updated robots.txt file that clearly states what bots are allowed to do on your website.

However, two major challenges to preventing web scraping exist. Firstly, some web scraping prevention methods can also impact real users and legitimate crawlers. Secondly, scraper tools and bots are becoming more sophisticated and better at evading detection, for example, by using rotating proxies or CAPTCHA solving to cover their tracks.

DIY Protection Measures Against Web Scraping

Below is a table of DIY protective measures that you can immediately take to prevent or minimize web scraping activities, especially price scraping and content scraping.

Step numberActionDescription
1Stay updatedTrack the latest web scraping techniques by following blogs (like ScraperAPI or Octoparse) that teach them
2Search for your own contentSearch for phrases, sentences, or paragraphs in your post enclosed in quotes
3Use plagiarism checkersCopyscape lets you search for copies of your web pages by URL or by copy-pasting text
4Check for typosquattingRegularly check for misspellings of your domain name to prevent content theft and typo hijacking
5Implement CAPTCHA (but don’t include the solution in the HTML markup)CAPTCHA differentiates humans from bots using puzzles bots can’t ordinarily solve. Google’s reCAPTCHA is a good option.
6Set up notifications for pingbacks on WordPress sitesPingback notifications alert you to use of your published backlinks and allow you to manually approve which of those sites can link to yours. This helps to prevent link spam and low-quality backlinks.
7Set up Google AlertsGet notified whenever phrases or terms that you’re using often get mentioned anywhere on the web.
8Gate your contentPut content behind a paywall or form, requiring sign-in to gain access. Confirm new account sign-ups by email.
9Monitor unusual activityAn excessive number of requests, page views, or searches from one IP address might indicate bot activity. Monitor this via network requests to your site or using integrated web analytics tools like Google Analytics.
10Implement rate limitingAllow users and verified scrapers a limited number of actions per time. This limits network traffic.
11Block scraping servicesBlock access from IP addresses of known scraping services, but mask the real reason for the block.
13Create a honeypotHoneypots are virtual traps or decoys set up to distract or fool malicious bots and learn how they work.
14Update your website/APIDynamic websites and updated HTML/APIs make it harder for malicious bots to scrape content.
15Disallow web scrapingEnact via your robots.txt file (e.g., www.yourURL.com/robots.txt), terms of service, or a legal warning.
16Contact, then report offendersReach out to the content thief letting them know they’re in violation of your terms of service. You can also file a DMCA takedown request.

While these DIY measures can help, their impact is limited in the face of ever-evolving threats like web scraping. Advanced, enterprise-grade web scraping protections are more effective, ensuring the security, integrity, and competitive edge that your site offers customers.

Advanced Protection Measures Against Web Scraping

Advanced web scraping solutions like WAF and bot protection provide enterprise-grade web scraping protection. They help to further protect your assets against unethical web scraping and can be used in conjunction with bot management best practices and other DIY anti-scraping measures.

3 ways to safeguard your website against DDoS attacks—and why it matters

DDoS (distributed denial-of-service) attacks are a type of cyberattack in which a hacker overwhelms a server with an excessive number of requests, causing the server to stop functioning correctly and denying access to legitimate users. The volume of these types of attacks is increasing, with a 56% year-on-year rise recorded in late 2024, driven by factors including the growing availability of AI-powered tools, poorly secured IoT devices, and geopolitical tensions worldwide.Fortunately, there are effective ways to defend against DDoS attacks. Because these threats can target different layers of your network, a single tool isn’t enough, and a multi-layered approach is necessary. Businesses need to protect both the website itself and the infrastructure behind it. This article explores the three key security solutions that work together to protect your website—and the costly consequences of failing to prepare.The consequences of not protecting your website against DDoS attacksIf your website isn’t sufficiently protected, DDoS attacks can have severe and far-reaching impacts on your website, business, and reputation. They not only disrupt the user experience but can spiral into complex, costly recovery efforts. Safeguarding your website against DDoS attacks is essential to preventing the following serious outcomes:Downtime: DDoS attacks can exhaust server resources (CPU, RAM, throughput), taking websites offline and making them unavailable to end users.Loss of business/customers: Frustrated users will leave, and many won’t return after failed checkouts or broken sessions.Financial losses: By obstructing online sales, DDoS attacks can cause businesses to suffer substantial loss of revenue.Reputational damage: Websites or businesses that suffer repeated unmitigated DDoS attacks may cause customers to lose trust in them.Loss of SEO rankings: A website could lose its hard-won SEO ranking if it experiences extended downtime due to DDoS attacks.Disaster recovery costs: DDoS disaster recovery costs can escalate quickly, encompassing hardware replacement, software upgrades, and the need to hire external specialists.Solution #1: Implement dedicated DDoS protection to safeguard your infrastructureAdvanced DDoS protection measures are customized solutions designed to protect your servers and infrastructure against DDoS attacks. DDoS protection helps defend against malicious traffic designed to crash servers and interrupt service.Solutions like Gcore DDoS Protection continuously monitor incoming traffic for suspicious patterns, allowing them to automatically detect and mitigate attacks in real time. If your resources are attacked, the system filters out harmful traffic before it reaches your servers. This means that real users can access your website without interruption, even during an attack.For example, a financial services provider could be targeted by cybercriminals attempting to disrupt services with a large-scale volumetric DDoS attack. With dedicated DDoS protection, the provider can automatically detect and filter out malicious traffic before it impacts users. Customers can continue to log in, check balances, and complete transactions, while the system adapts to the evolving nature of the attack in the background, maintaining uninterrupted service.The protection scales with your business needs, automatically adapting to higher traffic loads or more complex attacks. Up-to-date reports and round-the-clock technical support allow you to keep track of your website status at all times.Solution #2: Enable WAAP to protect your websiteGcore WAAP (web application and API protection) is a comprehensive solution that monitors, detects, and mitigates cyber threats, including DDoS layer 7 attacks. WAAP uses AI-driven algorithms to monitor, detect, and mitigate threats in real time, offering an additional layer of defense against sophisticated attackers. Once set up, the system provides powerful tools to create custom rules and set specific triggers. For example, you can specify the conditions under which certain requests should be blocked, such as sudden spikes in API calls or specific malicious patterns common in DDoS attacks.For instance, an e-commerce platform during a major sale like Black Friday could be targeted by bots attempting to flood the site with fake login or checkout requests. WAAP can differentiate between genuine users and malicious bots by analyzing traffic patterns, rate of requests, and attack behaviors. It blocks malicious requests so that real customers can continue to complete transactions without disruption.Solution #3: Connect to a CDN to strengthen defenses furtherA trustworthy content delivery network (CDN) is another valuable addition to your security stack. A CDN is a globally distributed server network that ensures efficient content delivery. CDNs spread traffic across multiple global edge servers, reducing the load on the origin server. During a DDoS attack, a CDN with DDoS protection can protect servers and end users. It filters traffic at the edge, blocking threats before they ever reach your infrastructure. Caching servers within the CDN network then deliver the requested content to legitimate users, preventing network congestion and denial of service to end users.For instance, a gaming company launching a highly anticipated multiplayer title could face a massive surge in traffic as players around the world attempt to download and access the game simultaneously. This critical moment also makes the platform a prime target for DDoS attacks aimed at disrupting the launch. A CDN with integrated DDoS protection can absorb and filter out malicious traffic at the edge before it reaches the core infrastructure. Legitimate players continue to enjoy fast downloads and seamless gameplay, while the origin servers remain stable and protected from overload or downtime.In addition, Super Transit intelligently routes your traffic via Gcore’s 180+ point-of-presence global network, proactively detecting, mitigating, and filtering DDoS attacks. Even mid-attack, users experience seamless access with no interruptions. They also benefit from an enhanced end-user experience, thanks to shorter routes between users and servers that reduce latency.Taking the next steps to protect your websiteDDoS attacks pose significant threats to websites, but a proactive approach is the best way to keep your site online, secure, and resilient. Regardless of your industry or location, it’s crucial to take action to safeguard your website and maintain its uninterrupted availability.Enabling Gcore DDoS protection is a simple and proven way to boost your digital infrastructure’s resiliency against different types of DDoS attacks. Gcore DDoS protection also integrates with other security solutions, including Gcore WAAP, which protects your website and CDNs.

From reactive to proactive: how AI is transforming WAF cybersecurity solutions

While digital transformation in recent years has driven great innovation, cyber threats have changed in parallel, evolving to target the very applications businesses rely on to thrive. Traditional web application security measures, foundational as they may be, are no longer effective in combating sophisticated attacks in time. Enter the next generation of WAFs (web application firewalls) powered by artificial intelligence.Next-generation WAFs, often incorporated into WAAP solutions, do much more than respond to threats; instead, they will use AI and ML-powered techniques to predict and neutralize threats in real time. This helps businesses to stay ahead of bad actors by securing applications, keeping valuable data safe, and protecting hard-earned brand reputations against ever-present dangers in an expanding digital world.From static to AI-powered web application firewallsTraditional WAFs were relied on to protect web applications against known threats, such as SQL injection and cross-site scripting. They’ve done a great job as the first line of defense, but their reliance on static rules and signature-based detection means they struggle to keep up with today’s fast-evolving cyber threats. To understand in depth why traditional WAFs are no longer sufficient in today’s threat landscape, read our ebook.AI and ML have already revolutionized what a WAF can do. AI/ML-driven WAFs can examine vast streams of traffic data and detect patterns, including new threats, right at the emergence stage. The real-time adaptability that this allows is effective even against zero-day attacks and complex new hacking techniques.How AI-powered WAP proactively stops threatsOne of the most significant advantages of AI/ML-powered WAFs is proactive identification and prevention capabilities. Here's how this works:Traffic pattern analysis: AI systems monitor both incoming and outgoing traffic to set up baselines for normal behavior. This can then allow for the detection of anomalies that could show a zero-day attack or malicious activity.Real-time decision making: Machine learning models keep learning from live traffic and detect suspicious activities on the go sans waiting for any updates in the rule set. This proactive approach ensures that businesses are guarded from emerging threats before they escalate.Heuristic tagging and behavioral insights: Advanced heuristics used by AI-driven systems tag everything from sessionless clients to unusual request frequencies. It helps administrators classify potential bots or automated attacks much faster.Ability to counter zero-day attacks: Traditional WAF solutions can only mitigate attacks that are already in the process of accessing sensitive areas. AI/ML-powered WAFs, on the other hand, can use data to identify and detect patterns indicative of future attacks, stopping attackers in their tracks and preventing future damage.Intelligent policy management: Adaptive WAFs detect suspicious activity and alert users to misconfigured security policies accordingly. They reduce the need for manual configuration while assuring better protection.Integrated defense layers: One of the strongest features of AI/ML-powered systems is the ease with which they integrate other layers of security, including bot protection and DDoS mitigation, into a connected architecture that protects several attack surfaces.User experience and operational impactAI-driven WAFs improve the day-to-day operations of security teams by transforming how they approach threat management. With intuitive dashboards and clearly presented analytics, as offered by Gcore WAAP, these tools empower security professionals to quickly interpret complex data, streamline decision-making, and respond proactively to threats.Instead of manually analyzing vast amounts of traffic data, teams now receive immediate alerts highlighting critical security events, such as abnormal IP behaviors or unusual session activity.

How AI helps prevent API attacks

APIs have become an integral part of modern digital infrastructure, and it can be easy to take their security for granted. But, unfortunately, APIs are a popular target for attackers. Hackers can use APIs to access crucial data and services, and breaching APIs allows attackers to bypass traditional security controls.Most companies focus on speed of development and deployment ahead of security when crafting APIs, making them vulnerable to issues like insecure authentication, poor validation, or misconfigured endpoints, which attackers can abuse. Additionally, the interconnected nature of APIs creates multiple endpoints, widening the attack surface and creating additional points of entry that attackers can exploit.As threats evolve and the attack surface grows to include more API endpoints, integrating AI threat detection and mitigation is an absolute must for businesses to take serious, deliberate action against API cyberattacks. Let’s find out why.Staying ahead of zero-day API attacksOf all the cyber attacks that commonly threaten APIs, zero-day attacks, leveraging unknown vulnerabilities, are probably the toughest to defeat. Traditional solutions rely more on the existence of preconfigured rules or signatures along with human interference to detect and block such attacks. This approach often fails against novel threats and can block legitimate traffic, leaving applications vulnerable and making APIs inaccessible to users.APIs must balance between allowing legitimate users access and maintaining security. AI and ML technologies excel at identifying zero-day attacks based on pattern and behavior analysis rather than known signatures. For instance, heuristic algorithms can detect anomalies, such as sudden spikes in unusual traffic or behaviors indicative of malicious intent.Consider the following example: A certain IP address makes an abnormally large number of requests to a rarely accessed endpoint. Even without prior knowledge of the IP or attack vector, an AI/ML-enhanced solution can flag the activity as suspicious and block it proactively. Using minimal indicators, such as frequency patterns or traffic anomalies, AI can stop attackers before they fully exploit vulnerabilities. Additionally, this means that only suspicious IPs are blocked, and legitimate users can continue to access APIs unimpeded.The risks of shadow APIsOne of the biggest risks is shadow APIs, which are endpoints that exist but aren't documented or monitored. These can arise from configuration mistakes, forgotten updates, or even rogue development practices. These unknown APIs are the ideal target for Layer 7 attacks, as they are often left undefended, making them easy targets.AI-powered API discovery tools map both known and unknown API endpoints, enabling the grouping and management of these endpoints so sensitive APIs can be properly secured. This level of visibility is critical to securing systems against API-targeting attacks; without it, businesses are left in the dark.API discovery as a critical security practiceWAAP with AI/ML capabilities excels in API security because it accurately checks and analyzes API traffic. The Gcore API discovery engine offers 97 to 99 percent accuracy, mapping APIs in users’ domains and using data to recommend policies to help secure APIs.How heuristics enhance WAAP AI capabilities to protect APIsWhile AI and ML form the backbone of modern WAAPs, heuristic methods complement them in enhancing detection accuracy. Heuristics allow the system to inspect granular behaviors, such as mouse clicks or scrolling patterns, which distinguish legitimate users from bots.For example, most scraping attacks involve automated scripts that interact with APIs in predictable and repetitive manners. In those cases, WAAP can use request patterns or user action monitoring to identify the script with high accuracy. Heuristics may define bots by checking how users interact with page elements, such as buttons or forms, and flagging those that behave unnaturally.This layered approach ensures that the most sophisticated automated attack attempts are caught in the net and mitigated without affecting legitimate traffic.Protect your APIs with the click of a button using Gcore WAAPAI offers proactive, intelligent solutions that can address the modern complexities of cybersecurity. These technologies empower organizations to secure APIs against even the most sophisticated threats, including zero-day vulnerabilities and undiscovered APIs.Interested in protecting your APIs with WAAP?

A vast 84% of organizations have experienced API security incidents in the past year. APIs (application programming interfaces) are the backbone of modern technology, allowing seamless interaction between diverse software platforms. However, this increased connectivity comes with a downside: a higher risk of security breaches, which can include injection attacks, credential stuffing, and L7 DDoS attacks, as well as the ever-growing threat of AI-based attacks.Fortunately, developers and IT teams can implement DIY API protection. Mitigating vulnerabilities involves using secure coding techniques, conducting thorough testing, and applying strong security protocols and frameworks. Alternatively, you can simply use a WAAP (web application and API protection) solution for specialized, one-click, robust API protection.This article explains 11 practical tips that can help protect your APIs from security threats and hacking attempts, with examples of commands and sample outputs to provide API security.#1 Implement authentication and authorizationUse robust authentication mechanisms to verify user identity and authorization strategies like OAuth 2.0 to manage access to resources. Using OAuth 2.0, you can set up a token-based authentication system where clients request access tokens using credentials. # Requesting an access token curl -X POST https://yourapi.com/oauth/token \ -d "grant_type=client_credentials" \ -d "client_id=your_client_id" \ -d "client_secret=your_client_secret" Sample output: { "access_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...", "token_type": "bearer", "expires_in": 3600 } #2 Secure communication with HTTPSEncrypting data in transit using HTTPS can help prevent eavesdropping and man-in-the-middle attacks. Enabling HTTPS may involve configuring your web server with SSL/TLS certificates, such as Let’s Encrypt with nginx. sudo certbot --nginx -d yourapi.com #3 Validate and sanitize inputValidating and sanitizing all user inputs protects against injection and other attacks. For a Node.js API, use express-validator middleware to validate incoming data. app.post('/api/user', [ body('email').isEmail(), body('password').isLength({ min: 5 }) ], (req, res) => { const errors = validationResult(req); if (!errors.isEmpty()) { return res.status(400).json({ errors: errors.array() }); } // Proceed with user registration }); #4 Use rate limitingLimit the number of requests a client can make within a specified time frame to prevent abuse. The express-rate-limit library implements rate limiting in Express.js. const rateLimit = require('express-rate-limit'); const apiLimiter = rateLimit({ windowMs: 15 * 60 * 1000, // 15 minutes max: 100 }); app.use('/api/', apiLimiter); #5 Undertake regular security auditsRegularly audit your API and its dependencies for vulnerabilities. Runnpm auditin your Node.js project to detect known vulnerabilities in your dependencies.  npm audit Sample output: found 0 vulnerabilities in 1050 scanned packages #6 Implement access controlsImplement configurations so that users can only access resources they are authorized to view or edit, typically through roles or permissions. The two more common systems are Role-Based Access Control (RBAC) and Attribute-Based Access Control (ABAC) for a more granular approach.You might also consider applying zero-trust security measures such as the principle of least privilege (PoLP), which gives users the minimal permissions necessary to perform their tasks. Multi-factor authentication (MFA) adds an extra layer of security beyond usernames and passwords.#7 Monitor and log activityMaintain comprehensive logs of API activity with a focus on both performance and security. By treating logging as a critical security measure—not just an operational tool—organizations can gain deeper visibility into potential threats, detect anomalies more effectively, and accelerate incident response.#8 Keep dependencies up-to-dateRegularly update all libraries, frameworks, and other dependencies to mitigate known vulnerabilities. For a Node.js project, updating all dependencies to their latest versions is vital. npm update #9 Secure API keysIf your API uses keys for access, we recommend that you make sure that they are securely stored and managed. Modern systems often utilize dynamic key generation techniques, leveraging algorithms to automatically produce unique and unpredictable keys. This approach enhances security by reducing the risk of brute-force attacks and improving efficiency.#10 Conduct penetration testingRegularly test your API with penetration testing to identify and fix security vulnerabilities. By simulating real-world attack scenarios, your organizations can systematically identify vulnerabilities within various API components. This proactive approach enables the timely mitigation of security risks, reducing the likelihood of discovering such issues through post-incident reports and enhancing overall cybersecurity resilience.#11 Simply implement WAAPIn addition to taking the above steps to secure your APIs, a WAAP (web application and API protection) solution can defend your system against known and unknown threats by consistently monitoring, detecting, and mitigating risks. With advanced algorithms and machine learning, WAAP safeguards your system from attacks like SQL injection, DDoS, and bot traffic, which can compromise the integrity of your APIs.Take your API protection to the next levelThese steps will help protect your APIs against common threats—but security is never one-and-done.

What are zero-day attacks? Risks, prevention tips, and new trends

Zero-day attack is a term for any attack that targets a vulnerability in software or hardware that has yet to be discovered by the vendor or developer. The term “zero-day” stems from the idea that the developer has had zero days to address or patch the vulnerability before it is exploited.In a zero-day attack, an attacker finds a vulnerability before a developer discovers and patches itThe danger of zero-day attacks lies in their unknownness. Because the vulnerabilities they target are undiscovered, traditional defense mechanisms or firewalls may not detect them as no specific patch exists, making attack success rates higher than for known attack types. This makes proactive and innovative security measures, like AI-enabled WAAP, crucial for organizations to stay secure.Why are zero-day attacks a threat to businesses?Zero-day attacks pose a unique challenge for businesses due to their unpredictable nature. Since these exploits take advantage of previously unknown vulnerabilities, organizations have no warning or time to deploy a patch before they are targeted. This makes zero-day attacks exceptionally difficult to detect and mitigate, leaving businesses vulnerable to potentially severe consequences. As a result, zero-day attacks can have devastating consequences for organizations of all sizes. They pose financial, reputational, and regulatory risks that can be difficult to recover from, including the following:Financial and operational damage: Ransomware attacks leveraging zero-day vulnerabilities can cripple operations and lead to significant financial losses due to data breach fines. According to recent studies, the average cost of a data breach in 2025 has surpassed $5 million, with zero-day exploits contributing significantly to these figures.Reputation and trust erosion: Beyond monetary losses, zero-day attacks erode customer trust. A single breach can damage an organization’s reputation, leading to customer churn and lost opportunities.Regulatory implications: With strict regulations like GDPR in the EU and similar frameworks emerging globally, organizations face hefty fines for data breaches. Zero-day vulnerabilities, though difficult to predict, do not exempt businesses from compliance obligations.The threat is made clear by recent successful examples of zero-day attacks. The Log4j vulnerability (Log4Shell), discovered in 2021, affected millions of applications worldwide and was widely exploited. In 2023, the MOVEit Transfer exploit was used to compromise data from numerous government and corporate systems. These incidents demonstrate how zero-day attacks can have far-reaching consequences across different industries.New trends in zero-day attacksAs cybercriminals become more sophisticated, zero-day attacks continue to evolve. New methods and technologies are making it easier for attackers to exploit vulnerabilities before they are discovered. The latest trends in zero-day attacks include AI-powered attacks, expanding attack surfaces, and sophisticated multi-vendor attacks.AI-powered attacksAttackers are increasingly leveraging artificial intelligence to identify and exploit vulnerabilities faster than ever before. AI tools can analyze vast amounts of code and detect potential weaknesses in a fraction of the time it would take a human. Moreover, AI can automate the creation of malware, making attacks more frequent and harder to counter.For example, AI-driven malware can adapt in real time to avoid detection, making it particularly effective in targeting enterprise networks and cloud-based applications. Hypothetically, an attacker could use an AI algorithm to scan for weaknesses in widely used SaaS applications, launching an exploit before a patch is even possible.Expanding attack surfacesThe digital transformation continues to expand the attack surface for zero-day exploits. APIs, IoT devices, and cloud-based services are increasingly targeted, as they often rely on interconnected systems with complex dependencies. A single unpatched vulnerability in an API could provide attackers with access to critical data or applications.Sophisticated multi-vector attacksCybercriminals are combining zero-day exploits with other tactics, such as phishing or social engineering, to create multi-vector attacks. This approach increases the likelihood of success and makes defense efforts more challenging.Prevent zero-day attacks with AI-powered WAAPWAAP solutions are becoming a cornerstone of modern cybersecurity, particularly in addressing zero-day vulnerabilities. Here’s how they help:Behavioral analytics: WAAP solutions use behavioral models to detect unusual traffic patterns, blocking potential exploits before they can cause damage.Automated patching: By shielding applications with virtual patches, WAAP can provide immediate protection against vulnerabilities while a permanent fix is developed.API security: With APIs increasingly targeted, WAAP’s ability to secure API endpoints is critical. It ensures that only authorized requests are processed, reducing the risk of exploitation.How WAAP stops AI-driven zero-day attacksAI is not just a tool for attackers—it is also a powerful ally for defenders. Machine learning algorithms can analyze user behavior and network activity to identify anomalies in real time. These systems can detect and block suspicious activities that might indicate an attempted zero-day exploit.Threat intelligence platforms powered by AI can also predict emerging vulnerabilities by analyzing trends and known exploits.

Why do bad actors carry out Minecraft DDoS attacks?

One of the most played video games in the world, Minecraft, relies on servers that are frequently a target of distributed denial-of-service (DDoS) attacks. But why would malicious actors target Minecraft servers? In this article, we’ll look at why these servers are so prone to DDoS attacks and uncover the impact such attacks have on the gaming community and broader cybersecurity landscape. For a comprehensive analysis and expert tips, read our ultimate guide to preventing DDoS attacks on Minecraft servers.Disruption for financial gainFinancial exploitation is a typical motivator for DDoS attacks in Minecraft. Cybercriminals frequently demand ransom to stop their attacks. Server owners, especially those with lucrative private or public servers, may feel pressured to pay to restore normalcy. In some cases, bad actors intentionally disrupt competitors to draw players to their own servers, leveraging downtime for monetary advantage.Services that offer DDoS attacks for hire make these attacks more accessible and widespread. These malicious services target Minecraft servers because the game is so popular, making it an attractive and easy option for attackers.Player and server rivalriesRivalries within the Minecraft ecosystem often escalate to DDoS attacks, driven by competition among players, servers, hosts, and businesses. Players may target opponents during tournaments to disrupt their gaming experience, hoping to secure prize money for themselves. Similarly, players on one server may initiate attacks to draw members to their server and harm the reputation of other servers. Beyond individual players, server hosts also engage in DDoS attacks to disrupt and induce outages for their rivals, subsequently attempting to poach their customers. On a bigger scale, local pirate servers may target gaming service providers entering new markets to harm their brand and hold onto market share. These rivalries highlight the competitive and occasionally antagonistic character of the Minecraft community, where the stakes frequently surpass in-game achievements.Personal vendettas and retaliationPersonal conflicts can occasionally be the source of DDoS attacks in Minecraft. In these situations, servers are targeted in retribution by individual gamers or disgruntled former employees. These attacks are frequently the result of complaints about unsolved conflicts, bans, or disagreements over in-game behavior. Retaliation-driven DDoS events can cause significant disruption, although lower in scope than attacks with financial motivations.Displaying technical masterySome attackers carry out DDoS attacks to showcase their abilities. Minecraft is a perfect testing ground because of its large player base and community-driven server infrastructure. Successful strikes that demonstrate their skills enhance reputations within some underground communities. Instead of being a means to an end, the act itself becomes a badge of honor for those involved.HacktivismHacktivists—people who employ hacking as a form of protest—occasionally target Minecraft servers to further their political or social goals. These attacks are meant to raise awareness of a subject rather than be driven by personal grievances or material gain. To promote their message, they might, for instance, assault servers that are thought to support unfair policies or practices. This would be an example of digital activism. Even though they are less frequent, these instances highlight the various reasons why DDoS attacks occur.Data theftMinecraft servers often hold significant user data, including email addresses, usernames, and sometimes even payment information. Malicious actors sometimes launch DDoS attacks as a smokescreen to divert server administrators’ attention from their attempts to breach the server and steal confidential information. This dual-purpose approach disrupts gameplay and poses significant risks to user privacy and security, making data theft one of the more insidious motives behind such attacks.Securing the Minecraft ecosystemDDoS attacks against Minecraft are motivated by various factors, including personal grudges, data theft, and financial gain. Every attack reveals wider cybersecurity threats, interferes with gameplay, and damages community trust. Understanding these motivations can help server owners take informed steps to secure their servers, but often, investing in reliable DDoS protection is the simplest and most effective way to guarantee that Minecraft remains a safe and enjoyable experience for players worldwide. By addressing the root causes and improving server resilience, stakeholders can mitigate the impact of such attacks and protect the integrity of the game.Gcore offers robust, multi-layered security solutions designed to shield gaming communities from the ever-growing threat of DDoS attacks. Founded by gamers for gamers, Gcore understands the industry’s unique challenges.
