A new penetration testing tool powered by artificial intelligence (AI) has been linked to a China-based company and has gained significant traction on the Python Package Index (PyPI), amassing nearly 11,000 downloads. Known as Villager, this framework is the product of Cyberspike, which has marketed it as an automated red teaming solution designed to streamline testing workflows.
Villager made its debut on PyPI at the end of July 2025, uploaded by a user known as stupidfish001, who is associated with a Chinese capture the flag (CTF) team named HSCSEC. Experts, including researchers from Straiker, have voiced concerns about the potential for Villager to be exploited by cybercriminals, drawing parallels to Cobalt Strike, a tool that has been widely adopted by malicious actors for various attacks.
The emergence of Villager follows revelations by Check Point regarding another AI-assisted security tool called HexStrike AI, which threat actors are also attempting to weaponize to target recently disclosed vulnerabilities. The rise of generative AI has enabled cybercriminals to enhance their tactics in social engineering and information operations, making these attacks faster and more efficient.
Villager’s ease of access and functionality could significantly lower the barrier for exploitation, reducing the time and expertise required to carry out sophisticated attacks. With capabilities like high-speed scanning and adaptive decision-making, attackers can exploit vulnerabilities on a much larger scale. The tool provides a streamlined way for bad actors to integrate automated attacks into their methodologies, posing an escalating threat to organizations worldwide.
Cyberspike itself was established in November 2023, and its AI tool is being marketed as a comprehensive solution that can effectively perform network attack simulations and assist in post-penetration evaluations. When installed, Villager reportedly includes various plugins enabling invasive functions such as remote surveillance, keystroke logging, and webcam access. Analysts found that it incorporates features similar to a known remote access tool, AsyncRAT, enhancing its malicious potential.
Villager operates within a context protocol framework that integrates with tools commonly used in penetration testing, allowing for natural language commands that can be transformed into technical actions. This AI-driven architecture significantly optimizes attack methodologies, transforming complex operations into simpler tasks that less experienced individuals can execute efficiently.
The implications of this tool extend well beyond its intended use for authorized testing, as its capabilities may complicate detection and investigation efforts. With its ability to establish ephemeral attack environments that erase their tracks, Villager represents a concerning advancement in the evolution of AI-driven cybersecurity threats, challenging the ability of organizations to detect and respond to such sophisticated intrusions effectively.
