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
