Ransomware - Malware

Ransomware is a type of malware that compromises computer systems, thereby restricting access to it or making files unusable until the user pays the demanded amount of money to the attacker or to the creator of the malware.

Ransomwares are capable of disrupting the operations of major enterprises or small businesses, as well as potentially wiping out individuals’ personal documents.

The ransomware family has rapidly grown with many new players such as Cryptowall, TeslaCrypt, LinuxEncoder creating havoc in Indian geographic region by gaining control of critical computer systems until a ransom is paid. Predominantly targeted towards gamers, the latest version of these malwares are now effectively being used to target Indian businesses & individuals.

When a victim visits a compromised website or downloads untrusted email attachments, the virus uses vulnerabilities in the browser (usually in plugins) or unpatched software’s/operating system to install Ransomware in the system & encrypts the victim’s files rendering them inaccessible.

It also displays warning indicating that the computer’s files have been encrypted & a set of detailed instructions on ransom payment modes to recover the files. However, there is no guarantee that the victims can recover the files even after making the payment.
