The A5/1 encryption algorithm used in (traditional) GSM networks was proven to be breakable by a brute force attack back in 2009/2010.

 

This means that GSM calls can be intercepted, decoded and listened to by anyone with the correct equipment. (SMS / Text messages can also be intercepted but that is a different story).

There are 40 files, roughly 1.6TB’s in size.  Below is a list of files included:

These files are/were available on bittorrent ( berlin tables ); the original source on reflextor.com is now unavailable.

We can supply the A5/1 Rainbow Tables to users via an external hard disk if required to both local and international customers.

The intent with this is to facilitate further research and experimentation in the GSM field.  Please feel free to leave a comment if you are interested in acquiring the A5/1 Rainbow Tables from ourselves.
