Recently, the FBI and The Department of Homeland Security (DHS) issued alerts to warn people of two types of malicious software or malware that the North Korean hackers are using to attack telecom, media, aviation, and finance industries.
One of the malwares is known as FALLCHILL and has been in use since 2016. It facilitates hackers to get access of and monitor infected computers remotely. The malware spreads when users accidentally download it by visiting infected websites. The DHS and FBI also mentioned that FALLCHILL uses multiple layers of ‘proxy malware’ to conceal its origin and makes it even more difficult to trace the hackers.
Another type of malware introduced by the North Korean hackers, named VOLGMER uses a spear phishing technique to infect computers. It sends a legitimate-looking email with a link that spreads the virus when clicked on. The US authorities say that North Korean computer hackers have been using this malware since 2013.
According to the DHS and FBI identified both the above mentioned malwares to be in association with HIDDEN COBRA, a term used by the US government to refer to the “suspicious & malicious cyber activity by the North Korean government.” In the recent years, North Korea has been linked to a few of the most high-profile, destructive cyber attacks that includes a $101 million theft from Bangladesh’s Central Bank in the year 2016, an attack on movie studio – Sony Pictures in 2014 and several disruptions to its neighbor South Korea’s systems. These hackers also have been accused of being the mind behind Wannacry Ransomware attack in May 2017 that caused a terrible loss to hundreds and thousands of computers across the world.
The North Korean cyber attacks have been making headlines for quite some time. However, the countries that are capable of doing so are constantly tracking, watching and spying on the capabilities of other countries. They usually attack the countries that fall beyond its immediate borders with cyber intrusions or missiles.
