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
