Locky ransomware definition

Locky ransomware is a serious global threat known for encrypting sensitive data on computers using complex encryption schemes, such as RSA and AES algorithms. This malicious software demands significant ransoms before providing victims with the decryption keys needed to recover their files. First detected in 2016, Locky ransomware has since evolved into several variants, causing widespread data loss across various industries.
