Title: What is CBC-mode and how to protect against such ransomware viruses
Post by: never on July 11, 2016, 10:09:44 am
Cipher Block Chaining(CBC) mode is a special process which includes a unique sequence of bits which are encrypted. They are grouped into a so-called unite or as the name refers - "block". This procedure also uses vectoring  and one of its defining details is that it also has a chaining mechanism which makes 1 of those "blocks" to rely on all of the previously encoded blocks, making them all connected together. This is very volatile, because if you try to decrypt the files, you will unknowingly rearrange those blocks, making the files lost forever. To put this into simple perspective, CBC is like a "dead man switch" and ransomware makers love it. Of course it is not easy to implement, but it is the next stage with such viruses and we will start seeing it more and more often.
