Ransom.Locky

Short bio

The Locky ransomware was first discovered at the beginning of 2016 and immediately became one of the major threats in the wild.

It is distributed through the use of both exploit kits and malspam. The Neutrino, RIG, and Nuclear exploit kits have all distributed Locky sporadically in the past.

Currently, the Necurs botnet is the main perpetrator behind the malspam resulting in Locky infections, usually as a result of a malicious Microsoft Office file or a ZIP attachment containing a malicious script.
