And now, the group named Shadow Brokers, that had leaked the tools from the USA national security agency's stockpile of cyber weapons, which were used by hackers for the recent attacks has said in a blog that it would be releasing hacking tools every month.
One risky PC malware, which starting May 12 has been proliferating worldwide, of late attacked companies, universities and even government departments within over 100 nations. The software held the victims' computers hostage and threatened to delete their files unless they paid $300. Brad Smith, Microsoft's top lawyer, criticized US intelligence agencies for "stockpiling" software code that can be used by hackers.
Over the weekend, ransomware was activated across unprotected Windows computers located in more than 150 countries around the world. As we detailed thoroughly on Monday, WannaCry is a risky trojan virus that infects Windows computers, encrypting almost all data in the process. Consider this map released by Malwareless.
The ransomware, identified as a malicious program called "WannaCrypt", demanded Bitcoin payments to unlock infected systems.
Microsoft, which on Friday took the unusual step of issuing a custom security update for users whose systems no longer receive regular support, has urged users with older versions of Windows to patch the vulnerability as soon as possible. WannaCry should not have reached disastrous proportions - Microsoft released a patch that could close the vulnerability in March, well before the NSA's tool was decrypted.
The China Daily pointed to the U.S. ban on Chinese telecommunication provider Huawei Technologies Co Ltd, saying the curbs were hypocritical given the NSA leak. "Yeah, we ought to".
Smith said that Friday's attack demonstrated how cyber security was becoming a shared responsibility between customer and supplier.
"It isn't clear that there has been a harm to consumers", he said.
"There are some rules and some policy that can be introduced where everybody knows how the government is going to handle these certain situations", said Greg Martin, CEO of San Francisco cybersecurity firm JASK and a former cybersecurity adviser to the FBI, Secret Service and NASA.
It's hard to blame Microsoft, Litan said, since it issued fixes and generally did what it should.
"The problem with suggesting policy is the answer to problems like this is it suggests that there's an easy answer", Ellis said.
No one is a bigger fan of technology than me-I love to learn about advances and am amazed by all of the innovations being developed by engineers, both from a hardware and software perspective.
The impact of WannaCry ransomware attack has been limited to five or six isolated instances so far and there are no reports of any substantial disruption to India's IT backbone, the government said today.
The attacks have now raised questions about the use of old software by organisations, and why United Kingdom health services were using old versions of Windows without support agreements.
