In the AI age, not all bots are created equal—and some are quietly overtaking the internet. According to the Thales/Imperva 2025 Bad Bot Report, AI-powered bad bots now account for 37% of all internet traffic, a 5% rise from last year. With their increasing ability to mimic human behavior and slip past traditional defenses, bad bots have become one of the most urgent threats to digital security. Let’s break down what this means, who’s most affected, and how companies can protect their platforms. How Big Is the Bot Problem? 37% of all internet traffic is now generated by bots. 41% of traffic on travel sites and a staggering 59% on retail platforms comes from bad bots. 45% of all bot attacks are now simple, high-volume attacks enabled by AI tools—up from 40% in 2023.

In the AI age, not all bots are created equal—and some are quietly overtaking the internet. According to the Thales/Imperva 2025 Bad Bot Report, AI-powered bad bots now account for 37% of all internet traffic, a 5% rise from last year. With their increasing ability to mimic human behavior and slip past traditional defenses, bad bots have become one of the most urgent threats to digital security.
Let’s break down what this means, who’s most affected, and how companies can protect their platforms.
How Big Is the Bot Problem?
- 37% of all internet traffic is now generated by bots.
- 41% of traffic on travel sites and a staggering 59% on retail platforms comes from bad bots.
- 45% of all bot attacks are now simple, high-volume attacks enabled by AI tools—up from 40% in 2023.
The barrier to entry has dropped: anyone with access to AI automation tools can now launch attacks without deep technical expertise.
Who Are the Main Culprits?
Here are the top offenders responsible for AI-based bot traffic in 2024:
- ByteSpider Bot (ByteDance/TikTok) – 54%
- Applebot – 26%
- ClaudeBot – 13%
- ChatGPT User Bot – 6%
While many of these bots are legitimate crawlers used for indexing content, cybercriminals are repurposing similar technology for malicious gains.
How AI Makes Bad Bots Smarter
Modern bad bots are nearly indistinguishable from real users. With the help of AI, these bots now:
- Mimic human interactions like mouse movement and typing speed
- Use residential IPs to blend into everyday traffic
- Bypass CAPTCHAs using AI image recognition
- Fake browser fingerprints and deploy cracked mobile apps
- Exploit privacy tools like iCloud Private Relay to mask origin
These tactics make detection extremely difficult for even the most seasoned cybersecurity teams.
Industries Under Siege
Bad bots don’t attack randomly—they target industries rich in data, APIs, and transactions, including:
- Retail: Bots hoard limited-edition products or scrape pricing data
- Travel: Bots grab seats or manipulate fare pricing in real time
- Media & Publishing: Bots scrape premium content and inflate ad fraud
- Finance: Bots simulate fake logins or target vulnerability in APIs
How to Defend Against AI-Powered Bad Bots
Here are proven methods organizations are implementing to tackle this threat:
Risk Assessment
Identify vulnerable endpoints, API access points, and business logic gaps.
Real-Time Monitoring
Use behavior analytics to detect abnormal user patterns and flag anomalies.
Block Known Data Centers and Bulk IPs
Restrict access from sources known to generate bot traffic.
Harden API Gateways
Protect APIs with rate limiting, token rotation, and IP whitelisting.
CAPTCHA and Biometrics
Use dynamic CAPTCHA, behavioral biometrics, and adaptive verification systems.
Bot Management Platforms
Invest in AI-based bot detection systems that evolve with threat patterns.
FAQs on AI-Powered Bad Bots
What is an AI-powered bad bot?
An AI-powered bad bot is an automated script that uses artificial intelligence to mimic human behavior, bypass security tools, and perform malicious activities such as data scraping, account takeover, and API abuse.
Why are AI bots harder to detect?
Because they use real-time learning, browser cloaking, and human-like behavior, they’re difficult to distinguish from actual users.
How do I know if my website is under bot attack?
Look for spikes in traffic, abnormally high API calls, or behavioral red flags like repetitive mouse movement, rapid-fire logins, and constant scraping of data-heavy pages.
Can CAPTCHA still protect against bots?
Not always. Many AI bots can now bypass static CAPTCHA. Advanced CAPTCHA and behavior-based challenges are more effective.
Are all bots bad?
No. Some, like Googlebot and Applebot, serve legitimate purposes like indexing content. The problem arises when similar technology is used for malicious or competitive advantages.
The rise of AI-powered bad bots marks a dangerous shift in how automated threats operate online. As these bots become more intelligent, widespread, and cheap to deploy, organizations must respond with advanced, adaptive defenses.
Ignoring the threat means not only risking security breaches but also losing customer trust, revenue, and control of your digital assets.
Your best defense? Understand, detect, and evolve faster than the bots.
