Security researchers recently discovered Locky Ransomware being spread on Facebook and LinkedIn. The malware is distributed by infected image and graphic files. Users are prompted to download a codec allowing them to view the file in question.
Once users download and open the malicious file they receive – all the files on their personal device are automatically encrypted and they can only gain access to them after a ransom is paid. The industry estimation is that the campaign is still raging and accumulates new victims every day.
Present anti-virus software does not detect the problem although, hopefully, that capability will be added soon.
