Technology giant Microsoft is
blaming the National Security Agency for the cyber extortion that hit hundreds of thousands of computer networks worldwide.
Tom Bossert, White House assistant to the president for homeland security and terrorism, said the ransomware infected more than 300,000 computers in 150 nations. "The good news is the infection rates have slowed over the weekend," he told reporters.
The ransomware extortion scheme is one of the largest computer attacks recorded.The attack involved remote break-ins of computers that scrambled key data inside infected systems, followed by offers from the attacker to unscramble the data if victims pay $300 in Bitcoin, the digital currency.
The ransomware used in the hack exploited
a vulnerability purportedly from NSA called EternalBlue, according to cyber security experts. Microsoft issued the patch shortly after the vulnerability was made public.
Bossert said the hackers have been paid less than $70,000 by victims so far.
Attacks by WannaCry, also called WannaCrypt, WCry, and Wanna Decryptor, were reported in China, Russia, Taiwan, France, and Japan, according to an FBI notice sent Saturday. The malware has been identified using 27 different languages.
Authorities are investigating who is behind the attacks, but
a Russian cyber criminal group is suspected.
Some cyber security investigators think North Korean hackers may have conducted the attack.
"
We don't know," Bossert said when asked who conducted the attack. "Attribution can be difficult here. I don't want to say we have no clues."
The FBI said the hacker or hacking group behind the ransomware
gained access to servers either by compromising Windows' Remote Desktop Protocol or by exploiting a critical flaw in its Server Message Block, a computer file-sharing system.
Microsoft issued a security update for the vulnerability on March 14, 2017.
