Submission + - Cracking Passwords with Amazon EC2 GPU Instances (stacksmashing.net) 1

suraj.sun writes: As of Nov-15, 2010, Amazon EC2 is providing what they call "Cluster GPU Instances": An instance in the Amazon cloud that provides you with the power of two NVIDIA Tesla “Fermi” M2050 GPUs. The exact specifications look like this:

        22 GB of memory
        33.5 EC2 Compute Units (2 x Intel Xeon X5570, quad-core “Nehalem” architecture)
        2 x NVIDIA Tesla “Fermi” M2050 GPUs
        1690 GB of instance storage
        64-bit platform
        I/O Performance: Very High (10 Gigabit Ethernet)
        API name: cg1.4xlarge

GPUs are known to be the best hardware accelerator for cracking passwords, so I decided to give it a try: How fast can this instance type be used to crack SHA1 hashes?

Using the CUDA-Multiforce, I was able to crack all hashes from this file with a password length from 1-6 in only 49 Minutes (1 hour costs 2.10$ by the way.). This just shows one more time that SHA1 is deprecated — You really don't want to use it anymore!

Submission + - Working shotgun built from Lego by 15-year-old (wired.co.uk) 2

Lanxon writes: A mildly terrifying young Brit named Jack Streat has managed to build a series of working guns, including a Lee Enfield bolt-action sniper rifle, entirely out of Lego and rubber bands, reports Wired. Streat, who lists himself as 15 years old on his profile, has constructed an enormous and diverse armoury of weaponry that fire either rubber bands or Lego bricks. Most are based on real-life guns, including a Steyr AUG, a Tommygun, an AK-47, a belt-fed M429 PARA, an Arctic Warfare sniper rifle, a Glock 17, a pair of semi-automatic TEC-9s, a SPAS 12 pump-action shotgun and a minigun that he calls the Obliterator.
