What is Crystalcrypt Ransomware? And how does it work?
Crystalcrypt ransomware is new cyber infection that encrypts files to make them inaccessible. This ransomware seems to be a different variant of the Lightningcrypt ransomware. Crystalcrypt is a real threat to small businesses and computer users’ data, web servers, databases, etc. It uses an executable file named zSd73pPjhvxBTTMtbRwO.exe to infiltrate your computer system. After that, it scans your computer for different file types listed below:
.3gp, .7z, .apk, .avi, .bmp, .cdr, .cer, .chm, .conf, .css, .csv, .dat, .db, .dbf, .djvu, .dbx, .docm, ,doc, .epub, .docx .fb2, .flv, .gif, .gz, .iso .ibooks,.jpeg, .jpg, .key, .mdb .md2, .mdf, .mht, .mobi .mhtm, .mkv, .mov, .mp3, .mp4, .mpg .mpeg, .pict, .pdf, .pps, .pkg, .png, .ppt .pptx, .ppsx, .psd, .rar, .rtf, .scr, .swf, .sav, .tiff, .tif, .tbl, .torrent, .txt, .vsd, .wmv, .xls, .xlsx, .xps, .xml, .ckp, .zip, .java, .py, .asm, .c, .cpp, .cs, .js, .php, .dacpac, .rbw, .rb, .mrg, .dcx, .db3, .sql, .sqlite3, .sqlite, .sqlitedb, .psd, .psp, .pdb, .dxf, .dwg, .drw, .casb, .ccp, .cal, .cmx, .cr2.
It then encrypts your file by appending the .BLOCKED file extension on the targeted files. It also drops several files in your computer like the CrystalCrypt_Recover_Instructions.png which will replace your desktop background and the Crystalcrypt_uniqueid.txt which contains your unique id that will be used when recovering your files and then the CrystalCrypt_Recover_Instructions.txt that contains the following message:
‘You became a victim of the CrystalCrypt Ransomware!
