Malicious

MAL-2024-12270

Ecosystem

pypi

Summary

Package imitates the legitimate fake-useragent, however it has a few suspicious additions: fake.py L149 calls a function from 'urllib2' module, which contains a code attempting to JSON-deserialize encoded code. This is a pickle executing os.system(id), which of course isn't executed by json.loads, but would be by pickle. Also: action is suspicious, not really malicious, but the package is a clear typosquatting attempt. --- Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities. Campaign: 2024-10-old-fake-usreagant Reasons (based on the campaign): - action-hidden-in-lib-usage - clones-real-package - typosquatting - dependency-confusion
