Getting conflicting reports on which variant we've been hit with. Also unclear of its typical attack vector. There was no website popup, email link, etc.

 

It appears to have maybe been through our RDP server? Ran wild in shares and ownership of all files is the Administrators group...

 

We have an Instruction.txt in every directory and all files end in aes. picture.jpg.aes for example.

 

We are able to restore 90% of our files from backups. Also, it seems that it stopped halfway through encrypting files...

 

Any help would be great, ransomID says it's Vortex, but I'm not Polish and our txt simply says:

 

"hello, all your files are irrevocably encrypted, to restore the data write to me on the mail: diesel@ nuke.africa send your personal ID:[long random string of letter and nukmbers]"

Any files that are encrypted with Vortex Ransomware will have the .aes extension appended to the end of the encrypted data filename and leave files (ransom notes) named ODZSZYFRUJ-DANE.txt, !!!-ODZYSKAJ-DANE-!!!.TXT as explained here.

Any files that are encrypted with Pulpy (Rozlok) Ransomware will have the .aes extension appended to the end of the encrypted data filename and leave files (ransom notes) named Instruction.txt as explained here.

Unfortunately, there is no known method that I am aware of to decrypt files encrypted by Pulpy (Rozlok) Ransomware without paying the ransom. If possible, your best option is to restore from backups, try file recovery software or backup/save your encrypted data as is and wait for a possible solution at a later time.

There is an ongoing discussion in this topic where victims 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.

To avoid unnecessary confusion, this topic is closed.

Thanks
