ransome-wanna cry

An unprecedented Cyber Attack (Ransomware) has affected more than 2 Lakh users in 150 countries on Friday including US, Britain, Russia amongst the most affected and has also affected computers in India. The initial attack, known as “WannaCry”, paralyzed computers that run Britain’s hospital network, Germany’s national railway and scores of other companies and government agencies worldwide in what was believed to be the biggest online extortion scheme ever recorded. The intensity of attack is likely to increase in coming week.
“The ransomware attack was particularly malicious, because if just one person in an organization clicked on an infected attachment or bad link, all the computers in a network would be infected”, said Vikram Thakur, technical director of Symantec Security Response.
