Banshee Stealer is a macOS information stealer active from at least 2024. It targets macOS Keychain data, web-browser data, and cryptocurrency wallets, and validates harvested or user-supplied passwords using native macOS directory-service authentication. It incorporates anti-analysis behavior, including checks intended to avoid Russian-language systems, and has been reported as capable of bypassing Apple XProtect. Banshee has been offered through a malware-as-a-service model and distributed while masquerading as legitimate applications, as well as through malicious advertising and trojanized free or cracked software. Its source code was leaked in 2024. Banshee was observed targeting macOS environments at multiple organizations and is part of a broader macOS stealer ecosystem alongside Atomic Stealer and Poseidon.
