Severity

High

Analysis Summary

Lazarus APT is one of North Korea’s most sophisticated threat actors, operating since at least 2009. Initially, they concentrated on South Korea. It has recently shifted its focus to worldwide targets and began initiating assaults for monetary gain. This actor has been linked to attacks in South Korea, the United States, Japan, and a number of other nations. Lazarus APT is suspected of being behind a number of diverse efforts, including cyberespionage, attacks on financial institutions, government agencies, and the military.

This group is said to be behind the wiper attack on Sony Pictures Entertainment in November 2014 as part of Novetta’s Operation Blockbuster campaign. Lazarus Group’s malware is linked to other known campaigns such as Operation Flame, Operation Troy, DarkSeoul, Operation 1Mission, and Ten Days of Rain. The Lazarus group uses trojanized malicious Windows and macOS applications to attack cryptocurrency firms. These programs are used to steal private keys and exploit security flaws in order to carry out fraudulent bitcoin transactions. In the last several years, these hackers have stolen at least $1.7 billion in cryptocurrencies. To manipulate their victims, Lazarus employs specific toolkits. The group tries to conceal its behavior, making malware detection and analysis more difficult.
