Details

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

Source: kam193 (9441463f029726ea263225e9b0092d82b049e2d7a4e059becd24f5e23c70a906)

Series of packages mostly with an obfuscated infostealer attempting to collect Chrome data. While discord webhook is usually set to an example, there are other, correct uploading URLs

Some of related packages only test partial malicious code, like webhooks from overwritten setup.py


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

Campaign: 2025-07-0x9xnx

Reasons (based on the campaign):

  • infostealer

  • obfuscation

  • exfiltration-browser-data

  • exfiltration-crypto

  • The package overrides the install command in setup.py to execute malicious code during installation.
