Hashing exploit threatens digital security

Celeste Biever writes on NewScientist.com:

Cryptographers have found a way to snip a digital signature from one document and attach it to a fraudulent document without invalidating the signature and giving the fraud away.

The development means that attackers could potentially forge legal documents, load certified software with bogus code, or turn a digitally-signed letter of recommendation into one that authorises access to private information.
