Infiniti Stealer: A new macOS infostealer using ClickFix and Python/Nuitka


A previously undocumented macOS infostealer has surfaced during our routine threat hunting. Malwarebytes Labs researchers initially tracked it as NukeChain, but shortly before publication, the malware’s operator panel became publicly visible, revealing its real name: Infiniti Stealer.

This malware is designed to steal sensitive data from Macs. It spreads through a fake CAPTCHA page that tricks users into running a command themselves: a technique known as ClickFix. Instead of exploiting a bug, it relies on social engineering. The final payload is written in Python and compiled with Nuitka, producing a native macOS binary. That makes it harder to analyze and detect than typical Python-based malware. To our knowledge, this is the first documented macOS campaign combining ClickFix delivery with a Nuitka-compiled Python stealer.
