Summary
Malicious code in timermcplib (PyPI)
Details

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

Source: kam193 (999846a0fc964a7818742a15f547ddd0b154f6ca559902c048c3f478a681c64c)

During import, the package automatically downloads and executes code that first acts as an infostealer and then starts code acting as a RAT. It connects with a hardcoded C2 server and waits for commands, supporting e.g. executing remote commands, exfiltrating files, recording the screen, executing GUI actions through PyAutoGUI.

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

Campaign: 2026-04-process-support

Reasons (based on the campaign):

  • exfiltration-generic

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

  • rat

  • spyware-like

  • infostealer

  • persistence

  • exfiltration-browser-data

  • exfiltration-crypto

  • files-exfiltration
