MAL-2026-15811
Malicious code in syswatch (PyPI)
Details
--- _-= Per source details. Do not edit below this line.=-_
## Source: kam193 (e01fd8b85a9d6bdfbefb70261f49496f8a6c224d98da6400ef0ca06f18404d27) During import, malicious code is started in the background. On Windows, it downloads and installs a malicious executable, and disguises it as a system utility. After installation, the code attempts to cover its tracks by cleaning logs and removing downloaded files. The installed executable is a heavily obfuscated malware with multiple sandbox evasion techniques, finally running an infostealer identifying itself as "Snow Stealer". It collects at least browser data and modifies cryptowallet applications.
