The point: AI agents automate complete attack chains without requiring zero-days, instead systematically exploiting known vulnerabilities and misconfigurations at machine speed.
Threat actors are increasingly deploying AI agents to automate all phases of cyberattacks — from lateral movement to compromise of cloud environments. The resulting attack velocity overwhelms classical defense mechanisms.
Security researchers from Sygnia recently documented an attack on a cloud environment in which threat actors, with AI support, chained together dozens of known vulnerabilities: from web application flaws through AWS misconfigurations to compromised secrets in version control systems and CI/CD pipelines. Automation enabled attackers to establish credential discovery, secret harvesting, cloud enumeration, data exfiltration and multiple persistence points within hours — operations that would have taken weeks or months manually.
A second case, documented by security firm Sysdig as “JadePuffer,” shows that AI agents do not need zero-day exploits: the attack exploited CVE-2025-3248, a vulnerability over a year old in Langflow, a tool for building AI agents. The autonomous agent performed credential harvesting, service mapping and persistence establishment independently. Researchers at the University of Toronto additionally demonstrated that AI-driven, self-replicating worms are capable of autonomously compromising dozens of simulated systems.
The central implication for CISOs: the classical assumption that breaches fail against advanced techniques no longer holds. Gidi Cohen, CEO of Bonfy.ai, states it clearly: “Most breaches do not fail due to lack of AI defenses, but due to unpatched systems, exposed services and weak identity controls.” AI merely accelerates the exploitation of these foundational gaps.
For incident response, this means a structural shift: the complexity of attacks is not the differentiating factor, but rather the speed and scale of exploitation. Organizations must recalibrate their defenses to operate in an environment where attackers work at machine speed, while traditional manual security processes lose relevance.
