North Korea Might Behind The Unprecedented Cyber-Attacks In The World

So far, the attacker behind WannaCry has made more than $49,000 (£37,900).

As some expert cyber security researchers from the USA said, there have been before also that Sony was hack due to the movie they were portraying the North Korean leader Kim Jong-un, but that was in 2014, and only affected one company.

More than 200,000 computers were crippled worldwide, the paper said, citing the European Police Office.

That's how most ransomware finds its way onto victims' computers. But similarities in lines of malware have been traced to earlier Lazarus attacks at least as far back as 2013, when South Korean media companies were targeted.

But the puzzle is how the first person in each network was infected with the worm. "We are not aware of payments that have led to any data recovery", White House Homeland Security adviser Tom Bossert said at a daily briefing on Monday.

It's hard to pin down who, exactly, is behind the WannaCry ransomware attack that kicked off last week.

The spread of the WannaCry attack - which encrypts a user's data and demands a "ransom" be paid electronically to free it up again - slowed to a trickle on Tuesday, with few, isolated examples being reported.

However, not everyone agrees that the North is behind the attacks.

Top South Korean government officials' smartphones were also hacked in 2016, according to the country's spy agency. The group is also thought to have been responsible for the Sony hack in 2014.

"We have not got any reports of widespread infection". "It requires a certain level of social interaction and file storage, outside of those with other hacking groups, that DPRK hackers and cyberwar units would not engage". He did not reveal the film's title, but said Disney would not pay up. In the past, this has included hot lines in various languages.

"They really aren't set up well to handle their bitcoin payments", Levin said.

"Neel Mehta's discovery is the most significant clue to date regarding the origins of WannaCry", said Russian security firm Kaspersky, but noted that more information was needed.

Although North Korea denied allegations that it was behind those events, Simon Choi, a senior researcher who has done extensive investigations into North Korea's hacking programs said the WannaCry program is "similar to North Korea's backdoor malicious codes".

The Lazarus hackers have however been more brazen in their pursuit of financial gain than others, and have been blamed for the theft of $81 million from the Bangladesh central bank, according to some cybersecurity firms.

In a blog post on Sunday, Brad Smith, Microsoft's chief counsel, stated that blame for the cyber-attack is on government agencies that hoard software and keep it secret. "However, the analysis of the February sample and comparison to WannaCry samples used in recent attacks shows that the code which points at the Lazarus group was removed from the WannaCry malware used in the attacks started last Friday".

By bundling a tool farmed from the leaked NSA files with their own ransomware, "they achieved better distribution than anything they could have achieved in a traditional way" he said.
