Cloudflare automates post-quantum secure web connections

Cloudflare says it's rolling out Automatic Key Exchange, a system that learns which encryption method each website prefers and uses that from the start. This cuts handshake time for web connections, lowering retries from 52% to 3.7% and shaving over 150 milliseconds off for most people. Hundreds of thousands of sites now have upgraded post-quantum security by default, with no manual setup needed.

Why it mattersFaster connections mean snappier websites and lower infrastructure costs. The shift to post-quantum encryption reduces risks from hackers storing today's traffic in hopes of breaking it when quantum computers arrive.

BigBear 2.0 phishing campaign hits Microsoft 365 accounts

Researchers at CloudSEK have identified a phishing-as-a-service campaign called BigBear 2.0 that stole over 5,100 Microsoft 365 credentials from users in at least 40 countries.
