Eric Lu factored an 862-bit RSA key for $400K using GPUs, putting RSA-1024 cracking costs at $30M and accelerating post-quantum crypto timelines.

Encryption at rest protects your files when your device is lost or stolen. Encryption in transit protects your data as it moves across the internet. You need ...

RSA-896, a 270-digit encryption benchmark, was factored on September 19, 2026, by Anthropic engineer Stephen Weis using ...

Cryptographers have been chipping away at RSA factoring records for decades, but the pace just got uncomfortably fast. On September 19, 2026, researcher Stephen A. Weis factored RSA-896, a 270-decimal ...

Hackers physically compromised a Flock camera and found an encryption key, 27,000 clips, and 1.6 million images generated in 21 days.

WTF?! It seems that Flock just can't stop making headlines these days – none of them good, of course. The latest report illustrating why so many cities are dropping the license plate readers involves ...

Project Phoenix doesn’t quite look like smart glasses, but it’s much smaller than Meta’s other headsets. Project Phoenix doesn’t quite look like smart glasses, but it’s much smaller than Meta’s ...

A researcher’s social media post revealing how to break part of a popular encryption protocol has gone viral. But did he really do it with just “good old pencil and paper”?
