According to research from the Georgia Tech Research Institute, the increasing use of graphics processors in normal computational tasks could bring new security risks.
V3.co.uk reports that general processing over GPU (GPGPU) platforms could trigger a dramatic increase the success rate for "brute force" password attacks:
The multi-threading capabilities of GPU chips could allow an attacker to increase the frequency of new password combinations and log-in attempts, allowing an attack tool to attempt to guess a system password.
Passwords under 12 characters could be vulnerable, says research scientist Joshua Davis. Davis says administrators should consider instituting alphanumeric passwords the length of entire sentences to keep their systems secured.
