It was mostly small variants released this week. We did have a new Cryptomix variant released, a wiper called UselessDisk disguised as a ransomware, and a strange report that Boeing had been infected with WannaCry. Overall, though, it has been a slow week.
Today MalwareHunterTeam discovered a new variant of the Cryptomix Ransomware that appends the .MOLE66 extension to encrypted files, changes the contact email, and slightly changes the ransom note's name. In the past, we used to see new variants a few times a month, but this time it has been almost 2 months since the previous variant.
