HexStrike-AI Abuse Marks Turning Point in Cyber Offense

HexStrike-AI has quickly emerged as a focus of concern in cybersecurity after reports confirmed its rapid adoption by malicious actors. Originally designed as a red-teaming tool, Check Point describes that “Hexstrike-AI provides threat actors with an orchestration ‘brain’ that can direct more than 150 specialized AI agents to autonomously scan, exploit, and persist inside targets.” This orchestration framework allows operators to automate complex offensive workflows that once required skilled manual effort. Within hours of its public release, chatter on underground forums revealed attackers experimenting with the tool to exploit Citrix NetScaler ADC and Gateway vulnerabilities disclosed in late August 2025. According to Check Point, this repurposing demonstrates how quickly an intended defensive platform can be transformed into a weaponized system. As Check Point summarizes, “This marks a pivotal moment: a tool designed to strengthen defenses has been claimed to be rapidly repurposed into an engine for exploitation, crystallizing earlier concepts into a widely available platform driving real-world attacks.”

The Citrix vulnerabilities tied to this wave of exploitation: CVE-2025-7775, CVE-2025-7776, and CVE-2025-8424, represent high-value targets for attackers. CVE-2025-7775 has already been confirmed as exploited in the wild, enabling unauthenticated remote code execution and the deployment of webshells onto affected appliances. ShadowServer data indicated that as of early September 2025, thousands of NetScaler instances remained exposed to CVE-2025-7775, despite a sharp decline from nearly 28,000 vulnerable systems just a week earlier. Check Point notes that “these vulnerabilities are complex and require advanced skills to exploit. With Hexstrike-AI, threat actors claim to reduce the exploitation time from days to under 10 minutes.” By automating reconnaissance, exploit development, and persistence delivery, HexStrike-AI lowers the barrier of entry and dramatically accelerates the pace of exploitation, compressing what defenders once considered critical patching windows.

Threat actors are using HexStrike-AI to scan for vulnerable NetScaler endpoints at scale, with some attackers moving quickly to monetize access by offering compromised appliances for sale. This behavior illustrates the dual role of the framework: not only is it being used to achieve initial compromise, but it is also being leveraged to maintain persistence and enable secondary criminal activity, such as data theft or access resale. The tool’s architecture—combining retry logic, intent-to-execution translation, and resilience mechanisms—ensures operations continue even when individual exploits fail. The practical effect is a new cycle of exploitation that is adaptive, relentless, and increasingly detached from the need for highly skilled operators. Check Point's analysis reinforce that HexStrike-AI represents a elevation in offensive tradecraft, leading to a future where AI-driven orchestration compresses the timeline between vulnerability disclosure and real-world exploitation to mere hours.
