Factors Found in 200-Digit RSA Challenge

diodesign writes "The two unique prime factors of a 200-digit number have been discovered by researchers at Bonn University (Germany) and the CWI (Netherlands). The number is the largest integer yet factored with a general purpose algorithm and was one of a series of such numbers issued as a challenge by security company RSA security in March 1991 in order to track the real-world difficulty of factoring such numbers, used in the public-key encryption algorithm RSA. RSA-200 beats the previous record number 11281+1 (176 digits, factored on May 2nd, 2005), and RSA-576 (174 digits, factored on December 3rd, 2003)."

Real Discovery!

I have found a way to crack any code in a matter of minutes. It's simple!!! It works plenty of times!!

Find out where the subject lives that encrypted the data. (1-3 days)

Break into their home. (10 minutes)

Look under their keyboard (1 minute)

Read their private and public key off the notecard taped under the keyboard. (2 minutes.)
Optionally: Steal the notecard and leave a fake one with the wrong key written down.
Laugh maniacally... Done!!!

To date when doing security sweeps at my various clients sites, 80% of staff have their password somewhere in their cube. 50% had their PGP keys under the keyboard, 10% had pen drives marked "Passwords" handing off a thumb tack on their cube wall. Who cares about better encyption, physical security (or perhaps mental security is a better choice) is where we need to focus.

And remember network admins! Have you users spade or neutered :)
