macOS screen-sharing flaw CVE-2026-65400 exploited to plant crypto miners, Apple patches it
Dutch cybersecurity officials warned that attackers are actively exploiting a high-severity macOS vulnerability in the screen sharing feature, gaining root access on exposed systems and installing Monero crypto miners. Apple issued a patch last week for Tahoe, Sequoia, and Sonoma after the flaw, rated 7.1 of 10, was disclosed at the Black Hat security conference; the company credited security firm Bynario with the finding.
