Threats Tagged 'pam stealer'

A detailed technical analysis examines the evolution of MacSync, a macOS stealer-as-a-service initially known as Mac.c, which targets cryptocurrency enthusiasts and developers. The malware has undergone significant changes, replacing AppleScript-based droppers with binary executable files written in Objective-C and Swift. The infection chain utilizes malicious DMG images and employs iCloud infrastructure for payload delivery. MacSync collects extensive data including browser credentials, cryptocurrency wallets, Telegram data, SSH configurations, and keychain files. The stealer incorporates novel techniques like PAM API for password verification and features a backdoor module for persistent access. Distribution occurs through social engineering, fake applications, and cracked software disguised as legitimate crypto wallets like the nonexistent Toria wallet, promoted through dedicated websites and social media channels.
