Runaway AI hacking agent behind WorkOS breach after escaping sandbox
WorkOS says an AI-powered hacking agent that breached its internal sales application and accessed customer information was operated by a security researcher who claims the tool escaped its testing environment and unintentionally attacked the company.
WorkOS says an AI-powered hacking agent that breached its internal sales application and accessed customer information was operated by a security researcher who claims the tool escaped its testing environment and unintentionally attacked the company.
The developer platform disclosed the breach earlier this week, saying an attacker used the ARTEX AI offensive security framework to automate reconnaissance and exploitation attempts against its systems.
However, in a new security update published Friday, WorkOS founder Michael Grinich revealed that the person responsible had come forward and claimed the incident was accidental.
The researcher reportedly was conducting cybersecurity benchmark evaluations using ARTEX when the agent operated outside its intended environment and began interacting with WorkOS systems.
WorkOS says its security team and an independent forensic investigator matched request details, timestamps, and other technical artifacts provided by the researcher against the company's logs, confirming with high confidence that the individual was responsible for the unauthorized activity.
WorkOS says the investigation also identified four security weaknesses that allowed the autonomous agent to access its internal sales application and extract customer information.
The affected application ran on a legacy internal tools platform that lacked the security protections used on the company's newer systems.
According to WorkOS, permissive access controls left the application's API endpoints exposed to the internet, allowing the agent to discover and interact with them.
This allowed the agent to authenticate after discovering the exposed endpoint.
The API also accepted a predictable credential intended for local development that had mistakenly been left deployed in production, and once authenticated, the agent abused the lack of rate limiting to rapidly retrieve records from the exposed application.
ARTEX is an AI-powered offensive security framework previously linked to cyberattacks against South Korean banks and the Dutch Institute for Vulnerability Disclosure (DIVD) .
The exposed information included business contact details, customer account histories, product usage information, and summaries or excerpts from sales calls, support discussions, and customer Slack conversations.
WorkOS says its investigation, validated by an independent forensic firm, determined that the incident was limited to data stored in its sales and customer support systems.
