Nemucod encrypts files on an infected computer and appends the .crypted file extension to their names. It then demands a ransom, typically requesting payment in Bitcoin, in exchange for decryption.
The affected files are not part of a separate Nemucod application or data format. They are the user's original files in encrypted form, and their contents depend on the files that Nemucod processed.
Emsisoft Decrypter for Nemucod and Trend Micro Ransomware File Decryptor are Microsoft Windows programs associated with recovery of files affected by Nemucod. The .crypted suffix was also used by a different ransomware known as ProposalCrypt in December 2016, so a decryptor must match the ransomware that created the files.
A .crypted file cannot normally be opened in its original application because its contents are encrypted. On Microsoft Windows, try Emsisoft Decrypter for Nemucod or Trend Micro Ransomware File Decryptor to decrypt the affected files.
After successful decryption, open the recovered files with the applications associated with their original file types. A .crypted file created by another ransomware may not work with these Nemucod decryptors.
There is no meaningful direct conversion from a .crypted file to another format. The file must first be decrypted with a compatible ransomware decryptor.
Once the original file has been recovered, it can be opened and exported or converted using an application that supports its original format.
