It is believed hundreds of thousands of crores have been at stake following the attacks.
“They used Ransomware, a type of malicious software designed to block access to a computer system to hack our systems. When we asked for decryption keys, they are demanding huge sums of money”, according to Devaraj, Chief of Cyber Security Forum.
The entire data of seven companies has has been locked by the hackers and demanding more than 2000 crore for giving back the decryption keys, it is learnt.
“They have used the servers located in Turkey, Somalia and Saudi Arabia. We have effectively busted some attacks, but several companies have been experiencing trouble still. We noticed that the cyber attacks have been taking place from Pakistani soil for the last ten days. Ransomware attacks have been on the rise of late” Mr Devaraj stated.
There is no guarantee that they would release all the keys even if the companies pay the ransom.
Some of the IT firms have complained about the attacks to NCSC directly and some have approached the Council through private cyber security institutions.
A total 2500 IT companies have located in Cyberabad area out of which 1300 are bigger ones having off-shore clients. The biggies are registered with NASSCOM.
