More information is needed to determine specifically what infection you are dealing with since there are many variants of crypto malware (file encrypting ransomware) and several which append a random 4, 5, 6, 7, 8 or character extension to the end of all affected filenames. For example, the newest variant of Crypt0L0cker appends a 6 lower alphabetic character extension.

Did you find any ransom notes? These infections are created to alert victims that their data has been encrypted and demand a ransom payment. Check your documents folder for an image the malware typically uses for the background note. Check the C:\ProgramData (or C:\Documents and Settings\All Users\Application Data) for a randomly named .html, .txt, .png, .bmp, .url file. Most ransomware will also drop a ransom note in every directory/affected folder where data has been encrypted.

You can submit samples of encrypted files and ransom notes to ID Ransomware for assistance with identification and confirmation. This is a service that helps identify what ransomware may have encrypted your files and then attempts to direct you to an appropriate support topic where you can seek further assistance. Uploading both encrypted files and ransom notes together provides a more positive match and helps to avoid false detections. If ID Ransomware cannot identify the infection, you can post the case SHA1 it gives you in your next reply for Demonslay335 to manually inspect the files.

Example screenshot:

Samples of any encrypted files, ransom notes or suspicious executable's (installer, malicious files, attachments) that you suspect were involved in causing the infection can be submitted here (https://www.bleepingcomputer.com/submit-malware.php?channel=168) with a link to this topic. Doing that will be helpful with analyzing and investigating by our crypto malware experts.

Is every file a different extension, and does it vary in length? Is the rest of the file renamed? The best way to identify will be with a ransom note.

<6 random characters>.

 

Is there any solution?

Sounds like crypt0l0cker, but without a ransomware note, we can't know for sure what this is.

Is the full filename renamed, or does it retain the original filename and just append the random extension? We need more information from you, and if you can share a zip file containing multiple encrypted files. I do not know what files you uploaded to ID Ransomware.

The file names are unaffected.

Change only the extension.
 

Attached 2 files :

Hmm. I only know of one ransomware right now that leaves the original filename but generates a random extension per file, and it can be 5-15 characters each file. It would have a ransom note "RESTORE_CORUPTED_FILES.HTML" and calls itself "Locked-In".

 

I don't see any common hex pattern between the files. Without a ransom note or malware sample, we can't really do much else to identify at the time.

Did you check for any malicious files so you could provide a sample?

These are some common folder variable locations malicious executables and .dlls hide:
  • %SystemDrive%\ (C:\)
  • %SystemRoot%\ (C:\Windows, %WinDir%\)
  • %Temp%\
  • %AllUserProfile%\
  • %UserProfile%\
  • %AppData%\
  • %LocalAppData%\
  • %ProgramData%\
Check the history logs and quarantine folders for your anti-virus and other security scanning tools to see if they found and removed any malware possibly related to the ransomare.
