Summary
Malicious code in k8s-node-health (PyPI)

Source: kam193 (9358111fecbdb3180b8f4c0c6543abff3024c59deaf488cf3a34089820e96172)

During import, the code download and starts remote executable that later connects to a C2 server, likely establishing a reverse tunnel. After executing the remote binary, the code performs covering-tracks actions by removing the binary from disk, and - depending on version - modifying the package code. The dropper code is either a Python script, or a compiled binary with obfuscated location of the remote binary and config for it.


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

Campaign: 2026-03-kube-health-tools

Reasons (based on the campaign):

  • Downloads and executes a remote executable.

  • backdoor

  • obfuscation

  • covering-tracks
