    Summary: Malicious code in multyproccess (PyPI)

    Details: Source: amazon-inspector (7938a109a642dfe8b161e9568d6373a038c3413c0fd1f2b01702f4f173348553) The package's setup.py overrides the install and develop cmdclass to base64-decode a bundled request/.payload file and launch it via subprocess.Popen([sys.executable, '-c', payload],...) with DETACHED_PROCESS|CREATE_NO_WINDOW at pip install time. The decoded payload is a Windows infostealer that enumerates Chrome/Edge/Brave/Opera/Vivaldi/Firefox profiles (cookies, logins, key4.db, autofill, saved cards), 50+ crypto wallet browser extensions and standalone wallet apps (Electrum, Binance, Ethereum), clipboard contents, email/FTP client credentials, and system fingerprint data, advertising a Chrome v20 ABE bypass. Collected data is exfiltrated to api.telegram.org/bot<TOKEN>/sendMessage and /sendDocument, and to https://recloud-blush.vercel.app; ipinfo.io is queried for geolocation. The payload also installs boot persistence disguised as svchost.exe, performs periodic screenshotting when crypto apps are active, targeted keylogging for passwords/seeds/private keys, and maintains a real-time C2 channel. The package name typosquats 'multiprocessing' while its metadata forges the publisher identity as 'Python Software Foundation' ([email protected], github.com/psf/request) and request/__init__.py re-exports symbols from the real requests library as a cover story. Source: kam193 (93a751dcfb2e5ac6058cbd62220d237288d3ceb4d8fe152b7ef7babb645df660) During installation, package executes an infostealer that e.g. exfiltrates browsers and crypto wallets data, establishes persistence, monitors clipboard. Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-08-multyproccess Reasons (based on the campaign): - typosquatting - infostealer - exfiltration-crypto - exfiltration-browser-data - clones-real-package - The package overrides the install command in setup.py to execute malicious code during installation. - The package contains code to detect if it is running in a sandbox environment. - obfuscation - persistence
