Source: kam193 (d91767b12efcd1ad71b86b8d6770f33ddd3f1bfdec795dc04fd1d743a63a4591)
Through an obscure way, one of the package files got overwritten by a remote obfuscated code, which appears to be an infostealer. After executing the malicious code, the package covers the tracks by overwriting all relevant code files.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
Campaign: 2024-11-asn1tool
Reasons (based on the campaign):
-
obfuscation
-
dependency-confusion
-
typosquatting
-
clones-real-package
-
infostealer
