Zibri has done it again! He went ahead and cracked the "new crypto algo" on 258f! Luckily, we have been once more given the source to his methods. Once again, Zibri is taking a page out of Master Hacker Richard Stallman's book, and using the one of his secret hacker tools (the source of which is here) he managed to decrypt the new firmware files. We are told that he has given this tool the name of zcat (it rhymes with scat) which is to be expected, given the naming of his other products.

We have also been given details on the cryptography behind the new so-called IMG3 crypto that Zibri has so masterfully cracked. The encryption is symmetric, in that the same secret is used both for encryption and decryption, and is elegant as it uses the exact same mathematical function in both directions. This function maps bijectively from nonnegative integers modulo 256 to the nonnegative integers modulo 256, such that the image of every value x in the domain is x. Another way of looking at it is as a stream cipher whose keystream is the set of values of the function f(x) = sin(x*pi) where x is the block index.

In older news, Zibri's secret is finally revealed! An anonymous contributor has provided me with the source to Zibri's most prized hacking tool, which is apparently called ztringz. Judging from the source, it was written by the superhacker Richard Stallman, so it's no surprise that Zibri is able to do such amazing feats with it. It is rumored to be so powerful that master hacker Zibri uses nothing but this tool to do his work, needing to know nothing else.
