## AI overview

This article analyzes a laboratory-generated Atomic macOS (AMOS) stealer infection observed on Aug. 5, 2026. It describes a deceptive macOS toolkit installation page that led users to paste a command into Terminal, retrieving a Zsh script containing an encoded compressed payload and a follow-up script designed to run a Mach-O binary. AMOS targets macOS and can exfiltrate system information, login credentials, and sensitive data from applications including browsers and cryptocurrency wallets.
