Cryakl Ransomware - How To Remove?
It seems that the cyber crooks, developing ransomware viruses, never get tired. There is this new Cryakl ransomware scaring the pants off unsuspecting users. Even though it utilizes the strong asymmetric encryption algorithm, cyber security experts have been able to crack it.
About Cryakl Ransomware
The executable of Cryakl cryptomalware is named schvost.exe. Once this file is on your computer’s system, it will begin to pave the way for the encryption procedure. When the system is completely devoured by this virtual piranha, the encryption process is begun. The files, having the following extensions, are targeted:
.dif, .dip, .djv, .djvu, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .dtd, .dwg, .dxf, .eml, .eps, .fdb, .fla, .flv, .frm, .gadget, .gbk, .gbr, .ged, .gif, .gpg, .gpx, .gz, .h, .htm, .html, .hwp, .ibd, .ibooks, .iff, .indd, .jar, .java, .jks, .jpg, .js, .jsp, .key, .kml, .kmz, .lay, .lay6, .ldf, .lua, .m3u, .m4a, .m4v, .max, .mdb, .mdf, .mfd, .mid, .mkv, .mml.
Cryakl file-encrypting virus appends ”.cryakl” extension to the filename extension of every encrypted file. For example, document.doc is changed into document.doc.cryakl. It gives 72 days, that are 3 days to pay the ransom and to get the decryption key to decrypt the corrupted data. The ransom note is very laconic. It reads as follows:
All your files have been
encrypted by Cryakl virus.
All the files were encrypted using
cryptographically strong AES algorithm.
Pay us in Bitcoins to get them back.
You have 72 hours.
The contact e-mail is not known. The size of the ransom either. It can be presumed that the victim will be introduced with the sum of money he/she is supposed to pay after the hackers behind Cryakl crypto malware have been contacted. However, under no means should one get in touch with these cyber criminals. Especially, when there is other means to retrieve your data. This way is completely free and safe.

How is Cryakl Ransomware Spread?
Cryakl crypto-malware is spread via two main methods. The first one involves spambots. These are the programs designed for sending spam. Do not get this wrong, it does not send typical spam e-mails which can hardly come into anybody’s notice. The spambots employed by ransomware viruses send deceptive letters such as ones informing the victim about unpaid taxes, fines and similar stuff. It is a pure social engineering kind of thing. You can even receive a secretive e-mail with no sender or no subject at all. The other method refers to malicious URLs which have malicious strings in their codes active. Their pathway to your computer is often assisted by exploit kits, such as Nuclear, Blackhole, Angler, etc. EKs, which identify the system’s vulnerabilities to injects these malicious codes.
How to Decrypt Files Encrypted by Cryakl Ransomware?
Cryakl Decryptor has been developed by IT experts of Kaspersky Lab. Feel free to use it. It is provided completely free of charge. Just do not fail to remember that the malware must be removed as soon as it is possible. Apply powerful automatic malware removal tools such as Reimage or SpyHunter.

How to recover Cryakl Ransomware encrypted files and remove the virus
Step 1. Restore system into last known good state using system restore
1. Reboot your computer to Safe Mode with Command Prompt:
for Windows 7 / Vista/ XP
- Start → Shutdown → Restart → OK.
- Press F8 key repeatedly until Advanced Boot Options window appears.
- Choose Safe Mode with Command Prompt.
for Windows 8 / 10

- When it loads, select Enable Safe Mode with Command Prompt from the list of Startup Settings.
2.Restore System files and settings.
- When Command Prompt mode loads, enter cd restore and press Enter.
- Then enter rstrui.exe and press Enter again.
- Click “Next” in the windows that appeared.
- Select one of the Restore Points that are available before Cryakl ransomware has infiltrated to your system and then click “Next”.
- To start System restore click “Yes”.

Step 3. Restore Cryakl cryptomalware affected files using Shadow Volume Copies
If you do not use System Restore option on your operating system, there is a chance to use shadow copy snapshots. They store copies of your files that point of time when the system restore snapshot was created. Usually Cryakl crypto-malware tries to delete all possible Shadow Volume Copies, so this methods may not work on all computers. However, it may fail to do so.
Shadow Volume Copies are only available with Windows XP Service Pack 2, Windows Vista, Windows 7, and Windows 8. There are two ways to retrieve your files via Shadow Volume Copy. You can do it using native Windows Previous Versions or via Shadow Explorer.a) Native Windows Previous Versions
Right-click on an encrypted file and select Properties → Previous versions tab. Now you will see all available copies of that particular file and the time when it was stored in a Shadow Volume Copy. Choose the version of the file you want to retrieve and click Copy if you want to save it to some directory of your own, or Restore if you want to replace existing, encrypted file. If you want to see the content of file first, just click Open.
b) Shadow Explorer
It is a program that can be found online for free. You can download either a full or a portable version of Shadow Explorer. Open the program. On the left top corner select the drive where the file you are looking for is a stored. You will see all folders on that drive. To retrieve a whole folder, right-click on it and select “Export”. Then choose where you want it to be stored.
Step 4. Use Data Recovery programs to recover Cryakl crypto malware encrypted files
There are several data recovery programs that might recover encrypted files as well. This does not work in all cases but you can try this:
- We suggest using another PC and connect the infected hard drive as slave. It is still possible to do this on infected PC though.
- Download Data Recovery Pro (commercial)
- Install and scan for recently deleted files.
Note: In many cases it is impossible to restore data files affected by modern ransomware. Thus I recommend using decent cloud backup software as precaution. We recommend checking out Carbonite, BackBlaze, CrashPlan or Mozy Home.
