    Details: Source: kam193 (67b219a81e6b2dd7db78b4b223da914ee7baefd0ab056940d3af0bc3b47846a0) Packages silently decrypt content hidden in a dependency and load them as Python extension modules.

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
