Details

During installation, package exfiltrates some basic info to a GitHub issue comment, and then attempt to set up a persistent infostealer focused on exfiltrating crypto wallets and browsers data. Likely continuation of 2026-05-py-requests

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

Campaign: 2025-06-alembic-util

Reasons (based on the campaign):

  • infostealer

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

  • crypto-related

  • Downloads and executes a remote malicious script.

  • exfiltration-browser-data

  • exfiltration-crypto

  • persistence

  • typosquatting
