Malicious code in fake-usreagant (PyPI)
Details
--- _-= Per source details. Do not edit below this line.=-_ ## Source: kam193 (ef713dc551a4b2eb9b0c94b270f4c214aa90e688076e15bb263b3bb5f3b8484b) 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
