Summary
Malicious code in asciitoart (PyPI)
Details

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

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
