mach-o man campaign

The mach-o man campaign tag covers reporting on a Lazarus Group operation targeting cryptocurrency and fintech executives through fake meeting invitations. The campaign, disclosed by CertiK in April 2026, uses convincing Zoom, Microsoft Teams, and Google Meet lures to persuade victims to paste malicious commands into the macOS Terminal. Coverage focuses on the campaign’s social-engineering approach rather than a software vulnerability, showing how attackers can use collaboration platforms and a victim’s own actions to deliver malware. Although the operation is aimed at Apple environments, its use of trusted meeting tools and command-pasting tactics offers a relevant security lesson for Windows teams and enterprise IT administrators.
