Washington, Dec 19: The United States has for the fist time publically blamed North Korea for being “directly responsible” for the WannaCry cyberayttack earlier this year.
The WannaCry virus infected about 200,000 computer systems in 150 countries in mid-May by exploiting vulnerabilities in Microsoft Windows, the most widely used operating system in the world.
The hack forced British hospitals to turn away patients, affected Spanish companies such as Telefonica, and threw other government agencies and businesses into chaos.
“After careful investigation, the US today publicly attributes the massive ‘WannaCry’ cyberattack to North Korea,” White House Homeland Security Adviser Tom Bossert wrote in an opinion piece in the Wall Street Journal newspaper on Tuesday.
“We do not make this allegation lightly. It is based on evidence. We are not alone with our findings, either. Other governments and private companies agree,” Bossert added.
“North Korea has acted especially badly, largely unchecked, for more than a decade, and its malicious behaviour is growing more egregious … WannaCry was indiscriminately reckless.”
Cyber security researchers from Symantec and Kaspersky Lab have said that some code in an earlier version of the WannaCry software had appeared in programmes used by the Lazarus Group, which researchers from many companies have identified as a North Korea-run hacking operation.
“This is the best clue we have seen to date as to the origins of WannaCry,” Kaspersky Lab researcher Kurt Baumgartner told Reuters news agency in May.
Malicious hackers belong in prison, and totalitarian governments should pay a price for their actions, Bossert asserted.
“The rest of us must redouble our efforts to improve our collective defences,” he wrote.
Bossert did not outline the US government’s specific plans to deal with cyberattacks, but officials in Washington said he was expected to do so later on Tuesday.
Marcus Hutchins, a young British computer security researcher credited with derailing the WannaCry attack, was later arrested for allegedly creating and distributing malicious software designed to collect bank-account passwords.
