What are Search Engine Bots?
A bot is software that automates tasks on the Internet. Depending on their purpose, bots can be beneficial or harmful.
Bots, short for "robots," are automated programs designed to perform repetitive tasks efficiently. They range from simple scripts to complex AI-driven systems interacting with websites & users. Bots can mimic human behavior to complete tasks. For example, they can index web pages, answer queries, or manage social media.
While good bots serve key functions like improving search results and customer service. Malicious bots exploit vulnerabilities for fraud, data theft, and cyberattacks. Some common bad bots include:
- DDoS Bots: Overwhelm servers with traffic, causing website downtime.
- Account Takeover Bots: Use stolen credentials to access user accounts.
- Scraping Bots: Extract web content without permission.
- Social Media Bots: Spread misinformation or manipulate engagement.
Bots account for much of bot traffic. Malicious bots often target websites, APIs, and mobile apps. Businesses that fail to detect and block harmful bots may face:
- Financial loss
- Compromised security
- Operational disruptions
Security measures include CAPTCHAs, bot detection tools, and access controls. They help mitigate risks and ensure smooth website performance.
How Do Bot Activities and Attacks Work?
Bot attacks serve various purposes, often driven by financial gain/disruption/cyber extortion. Attackers deploy bots to steal personal and financial data sold on the dark web for profit.
Some bot attacks target e-commerce websites and social media platforms. They overwhelm their services, causing financial loss through downtime. Cybercriminals also use bots to deploy ransomware. They demand payment to restore access to compromised systems.
Hacktivists may launch bot attacks to disrupt government operations or corporate activities. They can use automated threats as a form of protest or cyber warfare.
What ar the 5 Different Types of Bot Attacks?
1. Credential Stuffing
Attackers use stolen "usernames" and "passwords" to access user accounts on different websites. Bots automate multiple login attempts from various devices and IP addresses. It helps them blend in with legitimate traffic.
2. Web Scraping
Scraping bots extract content/data from websites by sending rapid "HTTP GET" requests. This stolen information can be repurposed for malicious activities/competitive intelligence/unauthorized redistribution.
3. DoS and DDoS Attacks
Attackers use DDoS bots to flood a site’s web application or server with excessive requests. It can cause "slowdowns" or "complete outages". These bots operate through infected devices in a botnet, executing commands remotely.
4. Brute-Force Attacks
Bots attempt to crack passwords by systematically guessing "possible combinations" & breaking "encryption keys." This method allows them to gain unauthorized access to user accounts & sensitive data.
5. Click Fraud
Bots mimic real users by clicking "ads", "buttons", or "links". It helps them manipulate web traffic and inflate engagement metrics. Bots are often used to increase ad revenue or fraudulently sabotage competitors.

How Can Companies Prevent Credential Stuffing and Credential Cracking Attacks?
1. Use Multi-Factor Authentication (MFA)
Requiring users to verify their identity with authentication factors adds a security layer. It prevents unauthorized access, even if "usernames" and "passwords" have been compromised. MFA helps block credential stuffing and brute-force password attacks.
2. Include Allowlists and Blocklists
Companies can prevent bad bot traffic from reaching their online assets. They can keep an allowlist of trusted IP addresses & a blocklist of malicious sources. It minimizes the risk of automated attacks.
3. Implement Bot Management Solutions
Advanced bot detection tools use "behavioral analytics", "machine learning", and "fingerprinting". It helps them identify and block malicious bots. Solutions like CloudPanel Bot Management analyze large volumes of traffic in real-time. They help distinguish between good and bad bots to safeguard websites, APIs, & applications.
4. Block or Use CAPTCHAs for Outdated User Agents and Browsers
Many automated bots rely on outdated user-agent lists. Blocking/using "CAPTCHAs" for older browser versions can help eliminate some bot traffic. It does this without affecting most genuine users, as modern browsers update automatically.
5. Restrict Known Hosting Providers and Proxy Services
Many bad bot operators launch attacks using 'cloud-based hosting services and proxies'. Blocking malicious traffic from "data centers" & "proxy networks" can reduce unwanted bot activity.
6. Secure APIs and Mobile Apps
Bots do not only target websites. "APIs" and "mobile applications" are also vulnerable. Organizations should extend 'bot detection and mitigation' measures across all digital platforms. It helps them close security gaps.
7. Analyze Traffic Sources and Patterns
Abnormal traffic spikes unusually high bounce rates. Unexplained low conversion rates may indicate malicious bot traffic. Regular monitoring helps detect and block malicious activity early.
8. Monitor Failed Login Attempts
A sudden rise in failed login attempts signals credential stuffing/account takeover attempts. Set "baseline login failure thresholds" and "automated alerts". It can help detect and block unauthorized access attempts.
9. Detect Suspicious Gift Card Activity
If there is an increase in failed gift card validation attempts, bots may test stolen numbers. Businesses should monitor traffic to "gift card validation pages" & restrict "excessive failed attempts".
10. Stay Alert to Public Data Breaches
Cybercriminals often use leaked credentials to launch credential-stuffing attacks. Monitor for stolen "usernames" and "passwords". It prompts users to change compromised credentials. It can help prevent 'account takeover bots' from gaining access.
11. Implement Bot Mitigation Solutions
Bots bypass traditional security tools. Advanced bot management solutions include "behavioral analytics", "machine learning", and "fingerprinting". These solutions can improve 'detection' and 'real-time mitigation'.
12. Use a Web Application Firewall (WAF)
A WAF can filter malicious bot traffic by blocking requests from identified bad bots. Advanced bots rotate through residential IPs. So, it is necessary to combine bot management solutions with WAF protection.
13. Exclude Bots from Google Analytics
Bot activity can inflate website traffic metrics. It makes it harder to track user behavior. Configuring Google Analytics can help you exclude known bots and improve data accuracy.
14. Watch for SEO Performance Drops
Stolen content may appear on other websites. Search rankings may decline due to duplicate content issues. Canonical tags ensure search engines recognize your site as the original content source.
15. Identify and Address Scalper Bots
Customers can complain about out-of-stock products despite the available inventory. Scalper bots may purchase items instantly. These bots harm customer trust and cause revenue loss.
Good Bot Management: Best Practices and Techniques

Execution of Bad Bots Attack | - Limit the "number of requests from a single IP" to prevent overwhelming your site. - Use machine learning to analyze user behavior and detect anomalies. - Block known "malicious IPs or IP ranges". |
Retooling After Bad Bots Attack | - Regularly review logs to identify and understand the attack patterns. - Patch "vulnerabilities", update "software", and strengthen security protocols'. - Use CAPTCHA to verify human interaction for actions like "login or form submissions". |
General Good Bot Management | - Use the robots.txt file to specify which bots can crawl your site and how often. - Filter out bots based on their 'user agent strings'. - Add an extra layer of security to prevent credential-stuffing attacks. - Use DDoS protection services to absorb & filter out malicious traffic during attacks. - Deploy a WAF to filter and monitor HTTP traffic to and from a web application. |
11 Common Types of Attacks that Help Identify Bad Bots
1. Layer 7 DDoS Attacks
A Layer 7 DDoS attack overwhelms a "website", "app", or "web application". It targets specific functions until they slow down or crash. These attacks cause significant financial loss. Organizations reportedly lose an average of $600 per attack.
2. Web Scraping
Web scraping bots extract web content such as "prices", "product details", & "proprietary data". Competitors may use scraper bots to undercut prices, duplicate content, & harm SEO rankings. They can outrank the source in search results without asking for user permission.
3. Click Fraud
Click fraud involves bots generating "fake clicks" and "impressions" on pay-per-click ads. This fraudulent activity costs businesses billions annually. It drains ad budgets without generating genuine leads or conversions. Bot activity mimics human interaction. It deceives platforms into counting illegitimate clicks as real engagement.
4. Account Takeover (ATO)
Account takeover bots use 'credential-stuffing attacks'. It helps them access user accounts with stolen usernames and passwords. Once inside, attackers steal "financial data", "personal information", or "linked bank accounts". It leads to identity theft and fraudulent transactions.
5. Spam Bots
Spam bots flood websites with malicious traffic. They post "spam comments", distribute "malware", or harvest "email addresses" for phishing campaigns. 54% of global email traffic is spam, which consumes resources and harms a brand’s reputation.
6. DDoS Bots
DDoS bots launch large-scale distributed denial-of-service (DDoS) attacks. They flood a targeted server with excessive traffic. It results in "service downtime", "revenue loss", and potential "data breaches". These attacks have grown in scale, with some reaching 500–700 Gbps.
7. Credential Stuffing Bots
Credential stuffing bots test stolen login credentials across multiple websites. They are often obtained from dark web breaches. These bots enable hackers to commit "fraud", "espionage", and "account takeovers". It leads to financial and reputational damage for businesses.
8. Malware Bots
Malware bots spread "viruses", "ransomware", and "spyware", compromising security systems. Attackers use these bots to:
- Gain access to user accounts
- Extract sensitive data
- Demand ransoms in exchange for restoring access
9. Ad Fraud Bots
Ad Fraud bots commit click fraud by generating fake "pay-per-click (PPC) ad clicks". They help inflate costs or increase ad revenue fraudulently. Advertisers pay high fees for ineffective campaigns with no real user engagement.
10. Credit Card Fraud Bots
CC Fraud bots conduct small unauthorized transactions to determine missing credit card details. Examples include "CVV codes" and "expiration dates". Once successful, they enable fraudulent purchases. It can lead to chargebacks for e-commerce businesses and harm their fraud risk scores.
11. Gift Card Fraud Bots
Gift Card Fraud bots target gift card accounts. Companies often lack stricter security measures for gift cards than credit cards. Gift card fraud can erode customer trust and result in business revenue loss.
