Got leftover GPUs? Why not crack some passwords?
Researcher Jeremi Gosney has used five servers, 25 Radeon GPUs, Infiniband and Virtual OpenCL to crack passwords at a scary rate.
What do you do with five 4U servers, 25 Radeon GPUs and Virtual Open Computing Language? Crack passwords, naturally.
As reported by The Security Ledger, researcher Jeremi Gosney created the cracking monster that's able to brute force a Windows XP (LM) password in six minutes.
While other password hashes take longer to crack, it's proof that the password, by itself, is not secure. Using the current set-up, the system should be scalable to "at least 128 AMD GPUs".
Bandwidth isn't an issue, with brute force methods "consistently [using]
