A new AI-powered penetration testing tool called 'Villager', linked to a suspicious Chinese company, has been downloaded over 10,000 times. Security experts warn it could be misused by cybercriminals, potentially becoming the AI successor to Cobalt Strike.

The Rise of AI-Powered Penetration Testing

A new artificial intelligence (AI)-powered penetration testing tool called 'Villager' has emerged, raising significant concerns in the cybersecurity community. Developed by a suspicious China-based company named Cyberspike, the tool has been downloaded over 10,000 times since its release in July 2025

.

The advent of generative AI models has enabled threat actors to enhance their social engineering, technical operations, and information gathering capabilities

2

. This trend is lowering the barrier to exploitation and reducing the time and expertise required to launch sophisticated attacks

Implications for Cybersecurity

The rapid adoption of Villager, with an average of 200 downloads every three days, highlights the growing interest in AI-powered offensive tools

1

. Security researchers emphasize the need for defenders to be aware of this emerging threat and to adapt their strategies accordingly

.

As AI continues to reshape the cybersecurity landscape, the line between legitimate penetration testing tools and potential weapons for cybercriminals becomes increasingly blurred. The case of Villager serves as a stark reminder of the dual-use nature of advanced security tools and the ongoing arms race between attackers and defenders in the digital realm.
