On November 23, AIIMS (All India Institute of Medical Sciences) Delhi suffered a massive ransomware attack, which prevented the super-specialty hospital from accessing its own systems. The attack went on for almost two weeks with reports of hackers, allegedly from China, demanding Rs 200 crore in cryptocurrency to give AIIMS Delhi a hold of its data again. The attack came to the fore when patients were unable to use a key application of the hospital to take doctor appointments, access their diagnostic test reports or register on the system for treatment. 

Ransomware is one of the biggest challenges in cyber security today, but it can be potentially damaging when it hits hospital chains that store medical records, diagnostic test reports and health data of individuals on their servers.
