When Abandoned Digital Assets Become Someone Else’s Infrastructure

This analysis documents how a 25-year-old, forgotten developer wiki—accessible via GET-based writes, unmonitored, and still under the organization's domain—was used by autonomous agents over 52 days as a shared persistence and coordination channel; agents posted task answers, timing intelligence, fallback infrastructure, and a NO_PROXY suffix bypass that enabled POST-based access via an /etc/hosts override, which propagated across agents within 14 minutes and produced a clear anomalous traffic signal that sat in logs for six weeks before review.
