WannaCry Ransomware Attack: What to Do Now

19 Mai 2017

NY [U.S.], May 14 (ANI): The World's biggest cyber attack which has hit 200,000 victims in at least 150 countries threatens to create more havoc on Monday when people return to work.

More cyber attacks are already reported and you can expect even more problems when people come into work on Monday and turn on their computers, only to realize they've become a victim of the virus, too.

GP practices in the North East of England, which were impacted by Friday's cyber-attack on the NHS, are now able to use their IT systems again.

When the computer virus struck on Friday 47 trusts were affected and seven had to close their doors in A&E to ambulances.

The cyber attack that crippled NHS computer systems is the biggest of its kind ever launched, security chiefs have said. "An equivalent scenario with conventional weapons would be the US military having some of its Tomahawk missiles stolen".

The worm encrypts data on an infected system, and then tells the user that their files have been locked and displays information on how much is to be paid and when - up to roughly $600 in bitcoin. (Note: the "Windows Update" section is also handy for showing you updates that are now being downloaded or applied.) Under "Advanced Options", just make sure the drop down box is set to "Automatic". The payment machines at 262 parking garages across the country didn't work due to the attack, which meant that customers couldn't pay for their parking and that Q-Park had to leave the booms open. However, many organizations - including hospitals - had not appropriately updated their systems.

Darien Huss, a senior security research engineer at Proofpoint, warned that "a new attack" was a major concern following the first cyber assault.

More than 150 countries have been affected, and we're in constant communication with worldwide partners, including Europol, Interpol and the Federal Bureau of Investigation and the collaboration has been strong and effective. "It was clear warnings were given to hospital trusts but this is not something that focused on attacking the NHS here in the United Kingdom".

Ryan Kalember, senior vice president at Proofpoint Inc, said on Sunday that millions of devices could be vulnerable if they haven't applied security patches over the weekend.

As per the advisory issued by CERT-In, the ransomware infects other computers on the same network and is also spreading through malicious attachments to e-mails. On Monday night the government said the ransomware - also known as Wana Decryptor, WannaCrypt and Wana - had affected eight Australian businesses, an increase from the "at least three" figure the government had claimed that morning.
