● Ransomware is a type of malicious software, used by cyber criminals, to infect a computer system by blocking access to the stored data by encrypting the files.
● A ransom is then demanded from the owner in exchange for the decryption key.
● While it is not yet clear as to how exactly the AIIMS computer systems were targeted, the malware may usually be injected remotely by tricking the user into downloading it upon clicking an ostensibly safe web link sent via email or other means, including hacking.
● It can spread throughout the network by exploiting existing vulnerabilities.
● Ransomware attacks can also be accompanied by theft of sensitive data for other sinister motives.
