What is .Lisp Ransomware? What it does?

.Lisp Ransomware is very notorious file virus and computer infection that is belongs to “STOP/DVJU Ransomware” family. Like other DJVU/STOP Ransomware’s variants, this nasty file virus operates by encrypting/locking all types/formats of files including images, audios, videos, games, pdf, ppt, xlx, css, html, text, documents, databases and other formats of files stored in your computer hard drive. It renames each file by appending .lisp File Extension and after encryption process is finished, “_readme.txt” text files as ransom notes are dropped in each folder of your computer that contain locked files.

.Lisp Ransomware is made using AES-256 encryption algorithm techniques by cybercriminals. If your files got locked with a specific encryption algorithm, which is completely unique and there are no other copies. So it is hard to recover files locked by this ransomware without the unique key available. However, “_readme.txt” ransom note states that all files of your computer have been locked and requires paying $490 – $980 amount of extortion money in Bitcoin cryptocurrency to decrypt your files. It claims that the only way to recover your files is to purchase & use its decryption keys, and in order to renames locked files manually or uses third parties’ decryption software, you will lose your all personal files & folders permanently.

After free decryption test successful, they force you to pay demanded ransom money to decrypt rest of the files. But it is bogus at all. You should never trust on them at any cases and avoid paying any amount of extortion money to them. If your System is already infected with this type of ransomware, then you should try to remove .Lisp Ransomware and all the related components from machine as soon as possible.
