Threats Tagged 'xmrig cryptominer'

This macOS malware campaign uses social engineering via fake CAPTCHA pages to trick users into running malicious AppleScript commands. It deploys a persistent backdoor that leverages EtherHiding by storing command-and-control (C2) addresses in Polygon blockchain smart contracts, complicating detection. The malware maintains persistence through LaunchAgents and delivers multiple payloads including the AMOS stealer, which targets cryptocurrency wallets, browser credentials, and macOS Keychain data, as well as the XMRig cryptominer for ongoing revenue. The campaign employs advanced evasion techniques such as character-ID obfuscation and abuse of legitimate macOS utilities. Blockchain transaction analysis reveals the full history of C2 infrastructure rotation and funding, aiding defenders despite the malware's memory-resident nature.
