Aircrack-ptw for the 770/N800

Since I compiled and tested Aircrack-ptw for my N800 for Erik as a benchmark anyway I now made a Maemo 770/N800 package for it.

Just add the right repository from my Maemo page and install it.

If you also want Aircrack-ng for your 770/N800 you can get it here: Aircrack-ng_0.5-1mad_armel.deb

Aircrack-ptw cracks WEP in 19 Seconds on my N800

I just benchmarked Aircrack-ptw on my Nokia N800 (ARMv6 320Mhz) and it finished in 19 seconds. Sadly enough the wireless packet injection doesn't work on the N800/770. 19 Seconds is quite impressive.

Breaking 104 bit WEP in less then 60 Seconds

Erik Tews with the help of two others published a new attack on WEP called: Breaking 104 bit WEP in less then 60 Seconds.

Like the older attacks on WEP this attack uses sniffed IVs in order to break/compute/crack the WEP key. The nice thing about this attack is that it only needs between 40.000 and 85.000 unique IVs (older attacks needed between 250.000 and 1.000.000 in order to succeed). This already reduces the overall attack time since one needs to capture less packages. But the attack also uses a new/other attack on RC4 which further improves the speed. The paper gives an average of 3 seconds on 1.7Ghz Pentium-M. The attack even works with 5000 keys.
