North Korean hackers behind WannaCry cyber attack

North Korea could be behind the WannaCry malware virus attack that paralyzed computers in more than 150 countries in May, according to the National Security Agency.

The Sony hack came after the company announced that they are planning to release the movie "The Interview" in 2014.

In May, a ransomware called "WannaCry" flounced across the world, locking computers while demanding payment for them to be unlocked.

Cybersecurity agencies in the United States and UK have pointed the finger at North Korea for the ransomware attack which hit the NHS.

The group has since been linked to attacks on banks in 18 countries, including a major theft from Bangladesh's central bank.

The officials of Britain's National Cyber Security Centre (NCSC) started their own investigation regarding the incident.

The ransomware did not target Britain or the NHS specifically, and may well have been a money-making scheme that got out of control, particularly since the hackers do not appear to have retrieved any of the ransom money as yet.

According to BAE Systems' Adrian Nish, the code seen in WannaCry is congruent with code seen in attacks previously linked to Lazarus.

The report out of the United Kingdom comes just days after the U.S. Department of Homeland Security and Federal Bureau of Investigation issued an alert attributing cyberattacks dating back to 2009 to North Korea is and warning of more. "The code-overlaps are significant".

The center's American counterpart, the National Security Agency, separately concluded with "moderate confidence" that the Lazarus Group unleashed WannaCry last month, USA intelligence officials told The Washington Post earlier this week.

The cash was then laundered through casinos in the Philippines.

Private sector researchers had already managed to reverse-engineer the software and find similarities between it and other malicious code developed by North Korea.

While WannaCry quickly became a global epidemic, it seems the attackers did not expect it to spread as fast as it did.
