An AI-native red-teaming framework called Villager is sounding alarms across the security community after racking up more than 10,000 downloads in just two months.
Developed by a shadowy Chinese firm, Cyberspike, the tool is being seen as an AI-powered successor to Cobalt Strike as it packages reconnaissance, exploitation, and lateral movement into a single automated pipeline. The tool also automates complex penetration testing workflows, integrates Kali Linux toolsets with DeepSeek AI models, and is available publicly on PyPI, further adding to security concerns.
“AI-assisted offense is here, has been here for quite some time now, and is here to stay,” said BugCrowd founder Casey Ellis, emphasizing the broad implications for bot defenders and attackers alike. “The net effect of this (Villager) is the availability of increasingly powerful capability to a far broader potential audience of users.”
Unlike traditional red-teaming tools that required specialized skill and time to operate, Villager can simulate attacks end-to-end with minimal human intervention, compressing days of work into minutes, AI security firm Straiker said in a blog post.
Villager can be weaponized for attacks
According to Straiker, Villager integrates AI agents to perform tasks that typically require human intervention, including vulnerability scanning, reconnaissance, and exploitation. Its AI can generate custom payloads and dynamically adapt attack sequences based on the target environment, effectively reducing dwell time and increasing success rates.
The framework also includes a modular orchestration system that allows attackers, or red teamers, to chain multiple exploits automatically, simulating sophisticated attacks with minimal manual oversight.
Villager’s dual-use nature is the crux of the concern. While it can be used by ethical hackers for legitimate testing, the same automation and AI-native orchestration make it a powerful weapon for malicious actors. Randolph Barr, chief information security officer at Cequence Security, explained, “What makes Villager and similar AI-driven tools like HexStrike so concerning is how they compress that entire process into something fast, automated, and dangerously easy to operationalize.”
Straiker traced Cyberspike to a Chinese AI and software development company operating since November 2023. A quick lookup on a Chinese LinkedIn-like website, however, revealed no information about the company. “The complete absence of any legitimate business traces for ‘Changchun Anshanyuan Technology Co., Ltd,’ along with no website available, raises some concerns about who is behind running ‘Red Team Operations’ with an automated tool,” Straiker noted in the blog.
Supply chain and detection risks
Villager’s presence on a trusted public repository like PyPI, where it was downloaded over 10,000 times over the last two months, introduces a new vector for supply chain compromise. Jason Soroko, senior fellow at Sectigo, advised that organizations “focus first on package provenance by mirroring PyPI, enforcing allow lists for pip, and blocking direct package installs from build and user endpoints.“
Straiker’s research shows that Villager leverages Python scripts to automate network discovery, vulnerability assessment, credential harvesting, and lateral movement, while AI-driven decision-making selects the most effective attack paths in real time. Automated reconnaissance and rapid exploitation can potentially compress detection and response windows, making attacks harder to stop.
Security teams are urged to monitor for unusual burst-like scanning, chained exploit attempts, and autonomous retuning behavior, while hardening identity policies and patch pipelines to reduce exposure. Additionally, Straiker recommended implementing MCP Protocol security gateways to monitor AI agent activity, audit third-party integrations, and establish internal AI governance frameworks for the use of tools. Building AI threat intelligence for tracking emerging techniques, an incident response playbook for rapid containment, and red-team exercises to validate AI-related security controls could help, too, they added.
