Any files that are encrypted with Nemucod Ransomware
will have the .crypted
extension appended to the end of the encrypted data filename and leave files (ransom notes) named DECRYPT.TXT.
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.Fabian Wosar
released a decryptor solution
for this type of infection.
Note: In some cases Nemucod will skip encrypting files despite appending the extension...it adds the extension first, then encrypts in a different manner so renaming the file and removing the .crypted extension should retore the file. Emsisoft's Decrypter for Nemucod has been updated to handle the files that are not really encrypted and only need to be renamed.Trend Micro
- Decryptor Released for the Nemucod Trojan's .CRYPTED Ransomware
In order to find your decryption key, you need to drag an encrypted file and unencrypted version of the same file onto the decrypt_nemucod.exe icon at the same time. To do this, you would select both the encrypted and unencrypted version of a file and then drag them both onto the decryptor.
- Emsisoft Decrypter for Nemucod
To use the decrypter you will require an encrypted file of at least 144 bytes in size as well as its unencrypted version. To start the decrypter select both the encrypted and unencrypted file and drag and drop them onto the decrypter executable.
has a Ransomware File Decryptor for victims of Nemucod infections
has a NemucodFR python script
with information on how to extract the key and use it to recover encrypted files by Nemucod Ransomware.
Unfortunately, there is no known way
at this time to decrypt files encrypted by the version of Nemucod which uses 7-zip
to encrypt the files without paying the ransom.
There is an ongoing discussion in this topic where you can post comments, ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.
Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. To avoid unnecessary confusion, this topic is closed.
