A new ransomware has emerged. Its name is Crysis, and it sets the extension .CrySiS to encrypted files. RSA algorithm and AES ciphers are combined for the encryption process. The ransom note is set as a picture on the desktop background. To remove this ransomware and see how you can try to restore your files, you should read the article carefully.
UPDATE! Kaspersky malware researchers have released a Shade decryptor which can decode files encoded by the the Shade ransomware variants. Since this includes the .xtbl file extension, we have created instructions on how to decrypt your .xtbl files. The instructions can be found on the link below:

Crysis Ransomware – Delivery
Crysis ransomware can be delivered in several ways. One is through spam emails containing a malicious file attached to it. If the attachment is opened, it automatically injects malware inside your computer. Malicious code could also hide in the body of the email. That means that you can get infected just by opening such an email, no matter if you tamper with the attachment.
Other ways this ransomware gets delivered are with the help of social networks and file sharing services, which could contain malicious attachments or files with the Crysis ransomware’s payload inside. The files could be presented to you as useful or things you need, such as an important update. Browsing unknown websites and clicking on redirect links can also lead to an infection from this malware.
Crysis Ransomware – Technical Information
The Crysis ransomware is classified by researchers as a ransomware. When a computer is infected with the ransomware, it creates an executable file, and it could make new Windows Registry values as a persistence measure.
The executable file could have different names and be randomly generated, but it has been detected in the following directory with the name written below multiple times:
%LOCALAPPDATA%\_Skanda.exe
The modifications in the Windows Registry are generally created in these registry entries:
HKLM/Software/Microsoft/WindowsNT/CurrentVersion/Winlogon/Shell
and
HKLM/Software/Microsoft/Windows/CurrentVersion/Run/
That also includes the ransomware setting itself to start automatically with each boot of the Windows operating system.
Next, the ransomware will create a file with a randomly generated name, which contains the ransom message. The instructions in it, describing how the ransom can be paid are always these:
Attention! Your computer was attacked by virus-encoder.
All your files are encrypted cryptographically strong, without the original key recover is impossible! To get the decoder and the original key, you need to to write us at the email:dalailama2015@protonmail.ch with subject “encryption” stating your id.
Write in the case, do not waste your and our time on empty threats.
Responses to letters only appropriate people are not adequate ignore.P.S. only in case you do not receive a response from the first email address within 48 hours please use this alternative email goldman0@india.com.
The file is a picture which is set as your desktop background after the encryption process is complete.
Two different emails are provided for contacting the developers of the Crysis ransomware. One registered as a domain in the Czech Republic and the other in India, but the origin of the ransomware is unknown. The cyber-criminals state in their ransom note that you should write to them if you want your files decrypted.
Contacting the ransomware creators for intending to pay for the ransom is NOT advised. No guarantee exists that your files are going to be unlocked and restored. Also, paying ransomware makers is almost the same as supporting their actions and encouraging them to make an even tougher variant of the malware.
The Crysis ransomware searches to encrypt various types of files. Files that could be encrypted have the following extensions:
→.odc, .odm, .odp, .ods, .odt, .docm, .docx, .doc, .odb, .mp4, sql, .7z, .m4a, .rar, .wma, .gdb, .tax, .pkpass, .bc6, .bc7, .avi, .wmv, .csv, .d3dbsp, .zip, .sie, .sum, .ibank, .t13, .t12, .qdf, .bkp, .qic, .bkf, .sidn, .sidd, .mddata, .itl, .itdb, .icxs, .hvpl, .hplg, .hkdb, .mdbackup, .syncdb, .gho, .cas, .svg, .map, .wmo, .itm, .sb, .fos, .mov, .vdf, .ztmp, .sis, .sid, .ncf, .menu, .layout, .dmp, .blob, .esm, .vcf, .vtf, .dazip, .fpk, .mlx, .kf, .iwd, .vpk, .tor, .psk, .rim, .w3x, .fsh, .ntl, .arch00, .lvl, .snx, .cfr, .ff, .vpp_pc, .lrf, .m2, .mcmeta, .vfs0, .mpqge, .kdb, .db0, .dba, .rofl, .hkx, .bar, .upk, .das, .iwi, .litemod, .asset, .forge, .ltx, .bsa, .apk, .re4, .sav, .lbf, .slm, .bik, .epk, .rgss3a, .pak, .big, wallet, .wotreplay, .xxx, .desc, .py, .m3u, .flv, .js, .css, .rb, .png, .jpeg, .txt, .p7c, .p7b, .p12, .pfx, .pem, .crt, .cer, .der, .x3f, .srw, .pef, .ptx, .r3d, .rw2, .rwl, .raw, .raf, .orf, .nrw, .mrwref, .mef, .erf, .kdc, .dcr, .cr2, .crw, .bay, .sr2, .srf, .arw, .3fr, .dng, .jpe, .jpg, .cdr, .indd, .ai, .eps, .pdf, .pdd, .psd, .dbf, .mdf, .wb2, .rtf, .wpd, .dxg, .xf, .dwg, .pst, .accdb, .mdb, .pptm, .pptx, .ppt, .xlk, .xlsb, .xlsm, .xlsx, .xls, .wps
After the encryption is fully finished, encrypted files have the .CrySiS extension. The encryption method used is suspected to be an RSA algorithm mixed with AES ciphers, like many other ransomware, because it is considered unbreakable.
The Crysis ransomware is known to encrypt the following file locations:
- %UserProfile%\Local Settings\Application Data
- %localappdata%
- %WINDIR%\System32
- %TEMP%
- %userprofile%\downloads
For the moment, it is unknown if Shadow Volume Copies are deleted from the Windows OS, but probably is the case. After removing the ransomware, you should see the fourth part of the instructions provided bel
