Ransomware is a class of malicious software that holds victim data hostage until an extortion payment is made. This activity typically involves encrypting private files, exfiltrating data with threats of public release, or both. Payment is usually demanded in cryptocurrency or prepaid store cards to complicate law enforcement tracking. [4]

Victims can sometimes recover encrypted files without paying extortion demands. Successful decryption without payment can occur through flaws in the malware code, leaked cryptographic keys, or instances where the software fails to properly encrypt the targeted systems. [4]
