Malware researchers at FireEye security firm have spotted a new Locky ransomware campaign mainly  targeting the healthcare sector. Security experts from FireEye have spotted a Locky ransomware campaign mainly targeting the healthcare sector, Telecom and Transportation industries. Attackers launched  a massive phishing campaign to deliver the threat. The campaign bit organizations worldwide, mostly in the US, Japan, South Korea. Threat actors behind this Locky campaign leveraged on DOCM FORMAT email attachments to deliver the ransomware, instead Javascript based downloaders. “From our trend analysis, Locky ransomware started being delivered via DOCM format email attachments more extensively beginning in August. This marks a change from the large campaigns we observed in March, where a JavaScript based downloader was generally being used to infect systems.” reads the report published by FireEye. “These detection spikes and change in tactics suggest that the cybercriminals are investing more to infect systems and maximize their profits. Additionally, we have observed that the delivery of Dridex via this distribution channel seems to have stopped, or nearly so, which could explain why we are seeing the Locky uptick.” The researchers believe crooks are investing to compromise systems maximizing their efforts. Another interesting trend reported by FireEye is the pause in the distribution of the Dridex banking Trojan through the same channel. Experts noticed many similarities in the macro code used by Attackers in three distinct Locky campaigns running on Aug. 9, Aug. 11 and Aug. 15.
