According to a report published by the Department of Homeland Security of the United States and the FBI, North Korea has a cyber army of thousands of hackers. They claim that this army has organized many attacks against other countries and companies for years.
Tension between the United States and North Korea has increased due to the missile tests of the North Korea. Now the US suggests that North Korea has a hacker army to organize regular attacks on other countries and companies. According to the claim made by the US Department of Homeland Security and the FBI, North Korea has launched many attacks with its hacker army since 2009. The last of these attacks is WannaCry software that appeared in the last months.
According to the report, North Korea has a hacker army called Hidden Cobra which consists of thousands of hackers. This army has many silos suitable for attacking cyber-attacks such as DDoS botnets, key loggers, remote access tools and various malwares and tools. The report calls this army Hidden Cobra, however it is underlined that the hacker army is well known as the names of the Peacekeepers and Lazarus in the media.
Namely, North Korea’s hacker army is the well-known Lazarus who hacked Sony and Bank of Bangladesh and seized millions of dollars. WannaCry could be Lazarus’ action. In fact, this point is well suited to the statements made by the security companies before, because it was known that Lazarus was supported by the North Korean government. In addition, for the WannaCry software, which infected 300,000 computers around the world last month, including hospitals, schools, banks and factories, many security companies, especially Symantec and Kaspersky, stated that this attack looked like the attacks of Lazarus and that the attack might have spread from North Korea.
According to the report, hackers are targeting computers with legacy Windows platforms, especially XP. While both Adobe and Microsoft said they shut down exploits on legacy platforms early last year, Microsoft Silverlight and Adobe Flash are still the number one way for hackers to infect computers and organize cyber-attacks. Because of that it is advised to keep the computers of the users always up to date while it is better to not use them if possible, since Silverlight and Flash will not be fully protected even if they are kept up to date.
On the other hand, North Korea rejects all these claims. It is also stated in the report that the South Korean institutions need to double their security. With these claims it is thought that the struggle between the North Korea and the US will shift to cyberspace.
