The Lazarus group is currently one of the most active and prolific APT actors. In 2018, Kaspersky published a report on one of their campaigns, named Operation AppleJeus. Notably, this operation marked the first time Lazarus had targeted macOS users, with the group inventing a fake company in order to deliver their manipulated application and exploit the hig

After we wrote our private report on the OilRig leak, we decided to scan our archives with our YARA rule, to hunt for new and older samples.

In April 2019, we discovered new malware that compromises encrypted web communications in an impressive way. Analysis of the malware allowed us to confirm that the operators have some control over the target’s network channel and could replace legitimate installers with infected ones on the fly. That places the actor in a very exclusive club, with capa
