Summary
Malicious code in heimdal-credentials (PyPI)
Details

-= Per source details. Do not edit below this line.=-

Source: kam193 (44b549b64558430b61d35bb2eb2cfcf8ec15d75bacb38af8f34deafe5d6add2c)

During import, only in specific environments, a module containing code disguised as telemetry is imported. This code then exfiltrates sensitive environment variables and cloud tokens to a hardcoded location, as well as starts a job listening for commands to execute. Likely dependency confusion attempts

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2026-02-amigapythonupdater

Reasons (based on the campaign):

  • exfiltration-generic

  • exfiltration-env-variables

  • The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.

  • dependency-confusion
