The report warns that Apple’s macOS screen sharing (VNC) implementation contains severe vulnerabilities introduced by Apple’s modifications to the VNC protocol; these flaws are being actively exploited and systems with screen sharing exposed should be considered compromised. It describes weak legacy VNC authentication, macOS firewall caveats, and provides command-line hardening steps plus recommendations to use VPN/SSH/Tailscale for secure VNC access.
