Hello, I need help with ransomware that can`t be determined - https://id-ransomware.malwarehunterteam.com/

I tried to upload  encrypted file and got

Unable to determine ransomware.

with link on this forum and SHA1: 24fc33244b44c31cc411e2a4875697c0105ded51

So, what is known about this ransomware:

- creates file %encryptedfilename%.id-6313903031165247-bitcoinrush@aol.com

- adds {72F6FU42-3SKE-218D-7215-9YAH5897321Y}.id-6313903031165247-bitcoinrush@aol.com in the beginning of file

- encrypts .doc, .zip, .rtf, and much more formats of files

- don`t creates ransom txt files

Now i don`t know where was this ransomware was taken... URL or mail...

I tried decrypt_hydracrypt with not encypted original file and his bitcoinrush@aol.com another file, tried Kaspersky`s rakhnidecryptor and rannohdecryptor - no success.

This looks like one of those "@" ransomwares, but has a bit of an anomaly. I've seen this before where, if you noticed by opening that XLS file with a hex editor or Notepad, the data is basically gone, and replaced by nul bytes basically. I'm not aware of a way of decrypting this one I'm afraid, or really why the file ends up blank (really concerns me).

 

You might try the usual recovery methods of trying ShadowExplorer, Recuva, and PhotoRec, you could get lucky.

What you have most likely seen is a file that has a second counterpart with the encrypted data. That's what these id-number-email ransomwares do lately. A part of the original file is encrypted and written into a second file. This encrypted part is zeroed out in the original and the email of the attacker is placed right in the beginning. If the file was large enough, there will be the non-encrypted part in the end of the zero bytes.

Ah, that makes more sense. Thanks for the explanation. I've only personally seen it with one other case so far.

There are going discussions in these related topics where you can ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions, comments or requests for assistance in one of the above topic discussions. Doing that will also ensure you receive proper assistance from our crypto malware experts since they may not see this thread. To avoid unnecessary confusion...this topic is closed.

Thanks
