  1. I can't decrypt my files in Windows 11 Pro


    I used Windows 10 Pro to encrypt files and I have the certificate and the password.I moved those files *.PFILE to a new computer running Windows 11 Pro, but every time I try to decrypt them through Properties>General Tab>Advanced, I can't see the option of decryption to unselect it, it only shows the option Encrypt contents to secure data unchecked.How can I do it?Thanks

  2. How to Decrypt *.cerber3 files?

    AFAIK it's still not possible to decrypt your files for free...

    In addition to what has been mentioned in the prior posts, you might want to read this:

    And I strongly suggest to read/do:

    Corrupted Win10 Profile, and Can't Decrypt Files

    Hey there, Andre:

    Thank you very much for your quick response. I finally got a chance to try troubleshooting per your suggestions. Here's what I came up with.

    I apologize if I wasn't clearer in my issue originally. The files themselves were never actually ON the same drive as the OS. THE OS was on drive C. My files were on drive F. However, I had somehow encrypted those files with my profile... and now that
    profile is corrupted.

    I tried the suggestions on that you linked, and these are my results:

    • Option 1: Change File Ownership to "Personal" in the context menu results in following error:
      • An unexpected error is keeping you from applying properties to the file. IF you continue to receive this error, you can use the error code to search for help with this problem.
      • Error 0x80071771: The specified file could not be decrypted.

    • Options 2 and 3: Decrypt Folder or File, (respectively), in Advanced Attributes:
      • Trying to remove encryption by deselecting the "Encrypt contents to secure data" checkbox in the Advanced Attributes window yields the following error:
        • An error occurred applying attributes to the file: F:\EXAMPLEFOLDER\EXAMPLEFILENAME: The specified file could not be decrypted.
    • Options 4 and 5: Decrypting Folders and Files in Command Prompt, respectively:
      • When running cmd prompt in Admin mode, and executing the cipher /d and cipher /d/s: commands, the following error is thrown:
      • F:\EXAMPLEFOLDER\EXAMPLEFILENAME\: the system cannot find the path specified.0 file(s) [or directorie(s) were decrypted.
      • This is problematic, because I can click on the folders and files themselves from the windows GUI.

    I still have the corrupted profile on my computer... is there a way to reach into it to extract the cipher?

    Thank you so much for your help! (Didn't expect to take a crash-course in Windows security, but there we are, LOL).

    Best,

    Chris

    How to Decrypt *.cerber3 files?

    Any files that are encrypted with Cerber Ransomware will be renamed with 10 random characters plus the
    .cerber (i.e. 2C1OlcaXdF.cerber, Ku7dYlcvkj.cerber) or .cerber2 extension (see

    here
    ) appended to the end of the encrypted data filename and leave files (ransom notes) named DECRYPT MY FILES#.vbs, DECRYPT MY FILES#.txt, DECRYPT MY FILES#.html.

    The newest variant of Cerber Ransomware will have a .cerber3 extension appended to the end of the encrypted data filename and leave files (ransom notes) named # HELP DECRYPT #.txt, # HELP DECRYPT #.html, and # HELP DECRYPT
    #.url.

    Trend Micro released a
    Ransomware File Decryptor
    for victims of earlier Cerber infections but it has limitations...must be used on the infected machine, may take several hours to complete decryption, some files may be only partially decrypted.
    However, victims of Cerber Ransomware have reported the decryption tool does not work on cerber3 encrypted files.

    In cases where a decryption tool does not work and you do not plan on paying the ransom, the only other alternative is to
    backup/save your data as is and wait for a possible breakthrough...meaning, what seems like an impossibility at the moment (decryption of your data), there is always hope someday there may be a potential solution so save the encrypted data
    and wait until that time. Imaging the drive backs up everything related to the infection including encrypted files, ransom notes and registry entries containing possible information which may be needed if a solution is ever discovered.

    There is an ongoing discussion in this topic where you can ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.
