Summary
Malicious code in pafex (PyPI)
Details

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

Source: kam193 (8ad1f51a6f081ac9e46b3d3ffa2d0b9b150b1600caf826d940f4e3d1992cda16)

In this campaign, the main package (resion) has an embeded pickle disguised as a config. A related dependency (pafex) contains code to load the pickle. During unpickling, malicious code embeded in the pickle file is automatically executed. It then establishes persistence via a PTH file and downloads the next stage payload. During analysis, the final remote payload was just a stub

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

Campaign: 2026-10-webreader

Reasons (based on the campaign):

  • files-exfiltration

  • obfuscation

  • The malicious code is intentionally included in a dependency of the package

  • Downloads and executes a remote malicious script.

  • The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.

  • rat

  • persistence

  • abuses-pth
