HackerSec's Yaga AI Agent Delivers Autonomous Penetration Testing with 98% Effectiveness

HackerSec has developed an autonomous penetration testing platform powered by its Yaga AI agent, marking a shift from scripted automation to adaptive, decision-making offensive security operations. Unlike traditional tools that follow predefined checks, Yaga observes the target environment, interprets responses, forms hypotheses, and replans attack paths in real time while maintaining memory and state across findings. The system relies on a proprietary harness that coordinates advanced AI models, security tools, contextual data, and ongoing decision logic rather than depending on a large language model alone. Yaga already achieves more than 98 percent effectiveness and supports continuous testing that matches the rapid change cycles of modern applications. CEO Andrew Martinez noted that periodic manual pentests can no longer keep pace with AI-accelerated attacks, requiring an AI-native model capable of operating at the same speed as the systems it protects. The platform allows human specialists to monitor and validate results while the agent conducts the investigation independently.

HackerSec has introduced an autonomous penetration testing platform driven by its Yaga AI agent, representing a fundamental change in how organizations can evaluate their defensive posture.

Traditional automated scanners execute fixed sequences of checks. In contrast, an autonomous agent continuously observes the target environment, interprets responses, generates hypotheses, and adjusts its strategy as new evidence appears. This ability to decide and replan during an engagement distinguishes true autonomy from sophisticated automation.

The key differentiator lies in system architecture. A single discovery in a real pentest can redirect the entire investigation. The agent must retain memory and state, correlate findings made at different times, select appropriate tools, and construct new attack paths. While advanced AI models are essential, they do not by themselves convert a tool into an autonomous pentester.

HackerSec built its platform around a proprietary harness specifically designed for offensive operations. This harness coordinates AI models, security tools, contextual information, memory, and decision-making throughout the engagement. The goal is to let the agent investigate an environment continuously while human specialists review and validate discovered issues.

Yaga currently achieves more than 98 percent effectiveness and signals HackerSec’s transition to an AI-native offensive security model. Rather than simply automating known tests, the platform enables the AI to lead the investigation, adapt its approach, and advance as it gains deeper understanding of the target.

“We are entering a reality where applications change every day and attacks are accelerating with AI,” said Andrew Martinez, CEO of HackerSec. “Conducting pentests two or three times a year is no longer sufficient. Offensive security must evolve into a continuous, autonomous model that tests systems at the same speed they change.”
