GSM A5/1 rainbow tables in Oslo, Norway

Posted on 2013-08-08 by Lasse Karstensen

The A5/1 encryption algorithm used in (traditional) GSM networks were proven to be breakable by brute force back in 2009/2010. This means that GSM calls can be intercepted, decoded and listened to by anyone. (SMS also, but that is a different story)

To do this easily you need a 1600 GB big rainbow table.

These files are/were available on bittorrent; a mirror of the torrents is available. The original source on reflextor.com is unavailable.

I’m offering the files for sale on disk or as paid download.

The intent with this is to facilitate further research and experimentation. Drop me an email and we’ll figure out the details.

Updated 2013-10-23: Clarified language.

Update 2016-05-10: Too much hassle shipping disk drives from outside the EU. From this point on I’m offering access to the files on FTP only.

Update 2024-04-23: Some interest still, 11 years after the original post. FTP server is still running. I’ve set up a small digital-products-store on https://payhip.com/b/k2hW3  to simplify the process.

    Is it not true that many GSM carriers now employ frequency hopping which makes the prior methods of capturing GSM calls obsolete?

    Hi,
    Due to b/w restrictions and speed in South Africa it would take me about 115 days to get the tables, are you still selling them? I’d love to get a copy!

    Hi Lasse,
    I have a few questions:
    1. http://hyse.org/a51torrents/ – it’s all tables? or do you have more?
    2. Why such a weird tables numbering?
    3. Which cover (from 2^64) the tables?
    Thanks in advance

      Hi Edgaras.

      This is the 40 .dlt files you can get over bittorrent. (“Berlin set”)
      I’m not familiar with any recent efforts in expanding it further. (better hitrate)

    Hi Lasse,

    I am interested in the disk version of the RTs. Are the RTs only the A51 or does it include the other RTs such as NTLM/SHA1/etc?

    Thanks in advance!
