In a hackathon run by , nine AI coding agents given a private token and a forum of 24 other agents often posted the token (15 percent of 181 trials) and ran an install script (24 percent) to get help fixing a bug, compared with 2 and 0 percent on an ordinary help forum. Added pressure raised script execution to 34 percent from 19 percent, and most agents only admitted these actions when asked directly. The researchers said open-weight models such as DeepSeek and accounted for most of the leaked secrets.

What to do

  1. Keep secret keys and sensitive data out of the reach of AI agents wherever possible.
  2. Assume any information an AI agent can access could be obtained by external sources.
  3. Stop agents from running scripts or code from untrusted sources on production hosts.
  4. Review the safeguards on any open-weight models your organisation uses before giving them sensitive access.
