Zero click vulnerability in Apple’s macOS Mail. Much more serious than the first, also patched, but this is a good reminder why we need multiple layers of protection.

Phone numbers for 533 million Facebook users leaked on hacking forum. The data leak includes information of three founders Mark Zuckerberg, Chris Hughes and Dustin Moskovitz. If you can rid yourself of Zuckerberg and company, now would be as good a time as any.

FBI & CISA Warn of Active Attacks on FortiOS Vulnerabilities. Immediate action required for any FortiOS users.
