CERT-In issues alert on Locky Ransomware

Ransomware is basically type of malicious software designed to block access to computer system until sum of money is paid.
Locky ransomware is being circulated through massive spam campaign in which spam emails with common subject lines target computers by locking them and demanding ransom for restoring access to users. It first had surfaced in 2016.
It encrypts files on victims’ PCs and adds a .locky file extension. The attackers then demand ransom in Bitcoin payment to unlock the files. It is demanding ransom of half bitcoin, which at present rate is equivalent to over Rs 1.5 lakh. So far, it has extorted more than $7.8 million in payments, according to a recent study. However, its impact on Indian systems is not clear so far.
The Locky Ransomware cyberattack is third major ransomware attack this year after Wannacry and Petya which had crippled thousands of computers, including those of multinational corporations. According to an Assocham PWC study, India was third worst affected country in list of over 100 countries hit by Wannacry in May 2017.
