Any files that are encrypted with the Payday (BTCWare) Ransomware variant will have the [<email>]-id-[id].payday extension appended to the end of the encrypted data filename and leave files (ransom notes) named !! RETURN FILES !!.txt. With this version, when a file is encrypted, the ransomware will modify the filename and then append the .payday extension to encrypted file's name (i.e. test.jpg.[Checkzip@india.com]-id-CE4.payday) as explained here.

.payday is based on the latest AES-256 version of the BTCWare Ransomware family which uses a different RSA-1024 key and is not decryptable unless you have the private AES key from the criminals. There is no way to bruteforce the key for this version.

You can submit samples of encrypted files and ransom notes to ID Ransomware for assistance with identification and confirmation.

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...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.

Thanks
