This week we saw numerous new variants of existing ransomware released, with only a few new families. The one new infection that was actively distributed this week is called UNNAM3D and was distributed through spam emails to about 30 thousand people. A parking garage in Canada got hit with the Darhma ransomware that caused them to shutdown their payment system. This let everyone who parked there to do so for free during the outage. A decryptor for the Hacked Ransomware was released today by Emsisoft that allows victims to recover their files for free.
