Package mentions being a research PoC, probably for dependency confusion, but the code is obfuscated making verification of the claim impossible.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
Campaign: GENERIC-questionable-pentest
Reasons (based on the campaign):
-
exfiltration-env-variables
-
exfiltration-generic
-
The package overrides the install command in setup.py to execute malicious code during installation.
-
typosquatting
