What happened
Microsoft Defender Experts linked 30+ rotating domains to MacSync Stealer, a macOS infostealer that exfiltrates Keychain data, browser credentials, SSH keys, AWS credentials, Kubernetes configs, and Apple Notes. Infection starts via ClickFix social engineering in a zsh Terminal session, followed by curl retrieving payload from attacker-controlled /curl/ paths, with data staged in /tmp/sync* and uploaded via chunked HTTP PUT requests.
Why it matters
Mac-using developers and founders should recognize the ClickFix social-engineering pattern (fake prompts instructing users to paste commands into Terminal) as the entry vector, and should treat unsolicited Terminal/curl instructions with suspicion. The stealer specifically targets AWS credentials, SSH keys, and Kubernetes configs, so anyone developing on macOS should audit whether sensitive credentials are stored in plaintext or browser sessions that this malware is known to collect.
Discussion angle
How ClickFix social engineering bypasses traditional security by tricking developers into running commands themselves—and whether your team has any guardrails for when AI-generated or copy-pasted terminal commands touch production credentials.
