Crypto Phishing Campaign Exploits AI-Generated Content
A crypto phishing campaign has been identified in which a threat actor employs AI-generated content to create 17,000 phishing lure sites impersonating more than 30 major cryptocurrency brands, including Coinbase, Crypto.com, Metamask, and Trezor.
Risk and Impact
By compromising login credentials and two-factor authentication (2FA) codes, attackers can gain unauthorized access to users’ crypto accounts, leading to potential financial losses and further exploitation.
The hackers were able to obtain seed recovery phrases, which allows attackers to completely take over victims’ wallets, rendering them irrecoverable.
Campaign Structure
The attack flow starts with AI-generated content on lure sites hosted on an otherwise legitimate developer platform GitBook.
Links to these initial lure sites are often distributed via website comments and a large proportion did not contain malicious content.
The sites include call-to-action (CTA) links that redirect users to phishing domains. These domains use UUIDs (universally unique identifiers) to track user visits.
The sites are registered with access keys and hosted on Amazon Web Services (AWS), ensuring reliable uptime and performance.
The report noted the use of AI to generate realistic and convincing phishing content enables attackers to create a vast number of phishing sites quickly and efficiently.
This content mimics legitimate crypto brand websites, making it difficult for users to distinguish between real and fake sites.
The report also noted examples where the LLM-generated content produced erroneous artifacts polluting the output of the final text, which do not appear to have been caught by the threat actor and suggest high levels of automation to generate these lures.
Adaptive Attack Behavior
The campaign showed adaptive attack behavior, where the lure sites moved to webflow.io with less sophisticated lures once blocked and taken down.
This adaptability enables attackers to quickly pivot and modify their tactics to evade detection.
Duncan said: “As we discovered, blocked and took down this campaign, we saw changing attacker behavior. Under pressure, the lure sites moved to webflow.io with less sophisticated lures.”
Conclusion
The identified crypto phishing campaign demonstrates the threat posed by AI-generated phishing content. The campaign’s scale and adaptability pose a significant challenge to cryptocurrency users and brands.
To protect against this threat, it is essential to remain cautious and take proactive measures, such as regularly monitoring for suspicious activity and employing robust security measures.
