On Saturday, about 100 countries, including India were hit by what is being termed as the biggest-ever recorded cyber attack that used “cyber weapons”, reported news agency PTI. While experts from top nations were busy dealing with the virus, it was a 22-year-old boy from England who ‘accidentally’ stopped the attack, reported The Guardian. According to the report, a researcher who identified himself as MalwareTech and works for Kryptos logic stopped the attack.
“I was out having lunch with a friend and got back about 3pm and saw an influx of news articles about the NHS and various UK organisations being hit,” he told the Guardian. “I had a bit of a look into that and then I found a sample of the malware behind it, and saw that it was connecting out to a specific domain, which was not registered. So I picked it up not knowing what it did at the time,” he added. The attack was first reported in Sweden, Britain and France.
A red-coloured ‘critical alert’ has been issued by the Computer Emergency Response Team of India (CERT-In), the nodal agency to combat hacking, phishing and to fortify security- related defences of the Indian Internet domain. “It has been reported that a new ransomware named as Wannacry is spreading widely. Wannacry encrypts the files on infected Windows systems. This ransomware spreads by using a vulnerability in implementations of server message block (SMB) in Windows systems. This is named as ETERNALBLUE,” an advisory issued by the CERT-In, accessed by PTI, said. This virus hacks computers and asks users to pay a ransom to access their files. It demands users pay 300 dollars worth of cryptocurrency Bitcoin to retrieve their files, as per the agency and spreads easily when it encounters unpatched or outdated software.
