Locky, a new strain of ransomware, appears to be borrowing a trick from Dridex banking malware. The malware uses embedded macros to execute malware that goes on to encrypt users files. At one point 3,680 successful Locky infections an hour via a command and control domain he registered, estimated that at its current rate, approximately a quarter of a million of PCs could be infected after just three days. Earlier this week reports surfaced that ransomware managed to cripple a Los Angeles area hospital, Hollywood Presbyterian Medical Center.
