Isn't this article missing a step?
I don't remember reading that encrypting the victim's files was part of the process - just curious! I'm sure we are not talking about fake ransomware here, but just the threat of data exposure is enough - if the victim already had the data encrypted, that would solve that wouldn't it? I simple restore from backup would work, because there is no malware resident in the files.
Yeah - I know - if the victim is that clueless, they aren't going to practice simple countermeasures or protections anyway - maybe they don't deserve to be in business then! Kind of like Darwin's rules here!
