A sophisticated cyber espionage campaign dubbed "Operation HollowQuill" has been uncovered targeting academic institutions and government agencies worldwide through weaponized PDF documents. The injection technique allows the bots to persist even when users navigate away from the initial compromised page, maintaining a distributed network of attack points that can be centrally coordinated through encrypted WebSocket connections.

Barracuda security researchers detected this threat after observing anomalous traffic patterns across client networks in February 2025. Their analysis revealed sophisticated evasion techniques and authentication bypasses not seen in conventional bot attacks, demonstrating advanced AI implementation beyond simple scripting. The Gray Bots leverage compromised websites, injecting JavaScript that creates a browser-based botnet from legitimate sessions. A new generation of sophisticated AI-powered Gray Bots has emerged, targeting web applications with unprecedented intensity. Unlike traditional attacks, they adjust traffic patterns to blend with legitimate activity, rendering rate-limiting defenses ineffective. Distributing requests across numerous IP addresses while cycling through user agents and employing randomized timing helps them evade detection systems. These bots utilize machine learning to mimic human behavior while generating over 17,000 requests per hour. The impact includes service degradation and security breaches at financial and e-commerce platforms.
