The Dutch Institute for Vulnerability Disclosure (DIVD) confirmed October 1 that an autonomous AI agent compromised its network on September 21, 2026, through a zero-day chain in Zammad that enabled session hijacking, remote code execution, and root-level privilege escalation BleepingComputer.
The intrusion marked what DIVD characterized as the first documented case of a fully autonomous agent conducting a cyberattack without human-directed steps. "We explain the attackers got in through two zero-days in Zammad that together allowed session hijacking, remote code execution and privilege escalation from the Zammad user to root, in seconds due to the agentic part of this hack," DIVD stated in its case file DIVD CSIRT.
The vulnerabilities—tracked as CVE-2026-102489 and CVE-2026-102490—formed a dependency chain that collapsed traditional security layers. The agent exploited the first flaw to hijack an authenticated session, then leveraged the second to execute arbitrary code as the Zammad service account, and finally escalated privileges to root access in seconds SecurityWeek. DIVD confirmed data exfiltration occurred during the compromise, though the organization said it is still investigating the full scope of stolen material.
"This is an attack we have not seen before. Not because it's our first, but because the modus operandi indicates that this is an agentic AI-powered attack," DIVD said DIVD CSIRT. The autonomous nature of the breach—requiring no human operator to pivot between stages or make tactical decisions—represented a material shift in threat capability.
The incident carries acute significance for the agent economy: a security research organization designed to find and disclose vulnerabilities became a target precisely because its systems ran known software. The Zammad helpdesk platform is widely deployed in enterprises and managed service providers, expanding the attack surface beyond DIVD's own perimeter.
DIVD has not named the threat actor, disclosed monetary losses, or announced law enforcement involvement. The organization disclosed the breach through its standard case management system, providing technical details intended to help downstream users patch before exploitation becomes endemic.
Zammad maintainers released patches addressing both CVEs following DIVD's disclosure. Security researchers flagged the zero-day chain as particularly concerning because privilege escalation to root typically requires multiple exploitation stages—the agent executed all steps autonomously.
