Summary
Malicious code in asynhttp (PyPI)
Details
-= Per source details. Do not edit below this line.=-
Source: kam193 (058c3bab076ccb770a3ecaefbdb301df88bd935a79f154cdeb329c51c4a1eef5)
Packages silently decrypt content hidden in a dependency and load them as Python extension modules.
In the first wave, those are copies of legitimate aiohttp and aiohappyeyeballs packages. In the second wave, malicious packages created good-looking forks of legitimate rich and pigments packages.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
Campaign: 2025-10-asynhttp
Reasons (based on the campaign):
-
typosquatting
-
exfiltration-generic
-
obfuscation
-
clones-real-package
-
native-extension
