What it detects

This rule detects HTTP uploads carrying the pinned axios/1.18.1 user agent to an /upload endpoint which the Contagious Interview RAT uses to exfiltrate stolen data to its controller. The fixed client library version paired with the upload path distinguishes implant traffic from normal browsing. It flags collected developer credentials leaving the host.
