The Indian Computer Emergency Response Team (CERT-In) on 2 September 2017 stated that the Locky Ransomware is spreading through massive spam campaign.

As per the reports, more than 23 million messages have been sent in this campaign. The messages contain common subjects like "please print", "documents", "photo", "Images", "scans" and "pictures". However the subject texts may change in targeted spear phishing campaigns.

The messages contain "zip" attachments with Visual Basic Scripts (VBS) embedded in a secondary zip file.

It is also reported that a spam campaign showing links to fake dropbox sites is being used to spread Locky variants.

If the pages are viewed in Chrome or Firefox, they show a fake notification stating “you don't have the HoeflerText font”. These fake notifications had an "update" button that returns a malicious JavaScript (.js) file.

The CERT-In advised the users to exercise caution while opening emails. The CERT-In also advised the organizations to deploy anti spam solutions and update spam block lists.

The ransomware is known to scramble contents of a computer or server and demands payment to unlock it "usually by anonymous decentralised virtual currency Bitcoins".
