Some outright rants from a bunch of infosec practitioners.

Pytacle alpha1 released!

Finally it’s here!

pytacle is a tool inspired by tentacle. It automates the task of sniffing GSM frames of the air, extracting the key exchange, feeding kraken with the key material and finally decode/decrypt the voice data. All You need is a USRP (or similar) to capture the GSM band and a kraken instance with the berlin tables (only about 2TB 😉 )

I’ve posted a preview before, take a look at the video to see the tool in action.

The tool is early alpha, so it’s working (for me 😉 ), but it’s neither rock stable nor packaged in any way. But still, I’ll be happy to get bug reports.

BTW, talking about Telco security: There will be another TelcoSecDay on 03/12/2013 at next year’s Troopers! We’ve already some quite interesting talks confirmed.
