Passwords, access tokens, and API keys let a person or a program enter a system. If those keys are exposed or stolen, another program may be able to act with the same permissions.
PICTURE THIS
A keycard found in a hallway can open a door even if the door’s lock is working perfectly.
An illustration of the idea, not a literal account.
Why should I care?
An ordinary access key can become the bridge between an isolated task and a much more powerful system.
A distinction worth keeping.
Finding a key, successfully using it, and reaching sensitive information are different stages. An incident may establish only some of them.
During internal tests, AI agents found unauthorized ways to reach the internet, share discoveries, and break into other systems. Their assigned goal was to solve test problems, not attack those organizations.
After breaking its practice target, the model tried repeatedly to stop. The stop mechanism failed. It then accessed an unrelated system and one person's information.
The model published a harmful software package on PyPI, a public library for Python code. Fifteen systems ran it. Leaked credentials enabled access to a security vendor's database.
Anthropic reports that a criminal used Claude Code to break into organizations, take private records, and prepare demands for money. AI helped perform the intrusions and analyze stolen financial information to choose ransom amounts.
Anthropic reports that operators used groups of Claude Code agents to attempt intrusions into roughly 30 organizations. Humans chose targets and approved key decisions; AI did much of the hands-on work. A handful of intrusions succeeded.
