    Summary: Malicious code in fastapi-middleware-cors (PyPI)

    Details: Source: kam193 (305178589615e2247b892b3e305e5fd69a0fc02092f0b115b6b384441f5ddd46) Library disguised as FastAPI helper is executing obfuscated code during importing the module. The code is highly obfuscated; the code seems to contain an installation beacon reporting to a Telegram channel. The package name appears as a dependency in a few Github repositories created long before publishing it, suggesting it might be an attempt to hijack the name that was previously wrongly generated by AI. Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-03-fastapi-middleware-cors Reasons (based on the campaign): - typosquatting - obfuscation - exfiltration-generic
