Exported functions hide the malicious functionality. 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.
