Ransomware

Ransomware is a malware that encrypts a user’s files and demands a ransom payment for the decryption key. It is done so that paying the ransom is far cheaper than the other alternatives.

Eg : WannaCry, Scorpion virus, etc.

Types

• Leakware / Doxware : Steals sensitive data [like private photos, credit card info.] and threatens to publish it unless ransom is paid.
• Wipers : Threatens to destroy data if ransom isn’t paid; sometimes destroys data even if it’s paid; used by nation-state actors or hacktivists.
• Scareware : Poses as an authoritative figure and demands a fine; uses social-engineering to make the user purchase ransomware disguised as antivirus software.
