Nordkorea-kopplad grupp undersöks av it-företag

Lazarus Group is a cybercrime group made up of an unknown number of individuals. While not much is known about the Lazarus Group, researchers have attributed many cyber attacks to them over the last decade. The earliest known attack that the group is responsible for is known as "Operation Troy", which took place from 2009-2012. This was a cyber-espionage campaign that utilized unsophisticated DDoS techniques to target the Seoul government of South Korea. They are also responsible for attacks in 2011 and 2013. It is possible that they were also behind a 2007 attack targeting South Korea, but that still isn't certain. A notable attack that the group is known for is the 2014 attack on Sony Pictures. The Sony attack used more sophisticated techniques and highlighted how advanced the group has become over time. The most recent attack attributed to the group is recent 2016 bank heist which included an attack on a Bangladesh bank, successfully stealing $81m. Symantec and white hat hacker Matthieu Suiche have found similarities between code found in the recent Wanna Cryptor attack and code found in previous Lazerus Group malware possibly linking the WannaCry outbreak to the group.
