Also known as Gold Burlap,and Cyborg Spider, Mespinoza is a malicious software that encrypts data and blocks access to it unless a ransom is paid. Mespinoza adds the “.locked” extension to each encrypted file. For example, “1.jpg” becomes “1.jpg.locked”, and so on. It also creates a ransom message within the “Readme.README” file. Programs of this type encrypt files with strong encryption algorithms, and thus victims cannot decrypt their files without the correct decryption tools.
