WannaCry Ransomware Attack: Here Everything you need to Know

19 May 2017, 09:42 | Megan Pierce

Some security researchers have said that it was possible for the North Korea-linked Lazarus Group to be behind the attack, but added that they would have to do more research. The cybercriminal will later demand a ransom for releasing the encrypted files. Recovery from backups is one of them.

"For Microsoft to say that governments should stop developing exploits to Microsoft products is naive", said Mr Brian Lord, a managing director at PGI Cyber and former deputy director at the Government Communications Headquarters, one of the UK's intelligence agencies.

What versions of Windows are affected?

The only real security from ransomware is backups and solid security best practices.

You should make multiple backups-to cloud services and physical disk drives, at regular and frequent intervals. Immediately disconnect your computer from the office/ home network.

The attacks exploited the computers because they were running outdated versions of Microsoft's Windows operating system.

The hack used a technique purportedly stolen from the US National Security Agency to target Microsoft's market-leading Windows operating system. Updating software will take care of some vulnerability. "I hope that if another attack occurs, the damage will be a lot less". "The options have good antivirus software and good malware software".

Vu Ngoc Son, deputy head of the anti-malware department of Bkav Corporation, the largest internet security firm in Vietnam, said that the WannaCry ransomware's behaviour is "not new", but he believes that the use of this ransomware will not really ease up as "it can directly earn large profits for hackers". Parts of the website may not work as expected without them.

How can we limit the virus from spreading?

.

Some organizations disconnect computers as a precautionary measure. "The objective of ransomware is to shut down critical information in networks and prevent access to this data". Normally, ransomware is spread by sending e-mails that have links attached to it.

The cyber criminals have demanded a fee of about Dollars 300 in crypto-currencies like Bitcoin for unlocking the device. There's also no guarantee all files will be restored.

ATM operators, however, say that there is no threat to customer data on money.

"Anyone forced to pay the ransom is guilty of dereliction of duty", Goldstuck said. "But at the same time, I also know that if you're someone who's been affected and you've lost all your children's photographs or you've lost all your data or you lost your thesis, sometimes $300 is worth it, you know?"
