On January 4, 2017, it was reported that India and Pakistan had once again traded cyberattacks. Pakistani group "Alone Injector" hacked the website of India's National Security Guard (NSG) and posted "offensive content" on it. Another Pakistani group, "Kashmir Cheetah," had attacked the official website of Cochin and Thiruvananthapuram airports on December 28. India infected three Pakistani airport websites with ransomware. In response to both attacks, on January 2, Indian hackers claimed to have hacked Islamabad, Peshawar, Multan International and Karachi airport sites and infected them with ransomware, blocking access on the part of the website's administrators. The Indian hackers demanded bitcoin in exchange for unlocking the websites.
The same Indian hacking group had previously attacked Pakistani targets with ransomware, locking the data of hundreds of computers, and had also leaked the personal and banking details of Pakistani army officers.Source: ehackingnews.com, January 4, 2017
