There are a new crypto ransomware variant that rename the file with:   WP_20151023_003.jpg.id-3660246556_email_info@cryptedfiles.biz


There are not any adding files about ransom info. The only things is a desktop background image 



Seems really similar to  fud@india.com
I tried rakhnidecryptor from karspesky, a week ago, and after a couple of hour working on a jpeg it claim to found the key, and next try to decrypt all HD. When finished I find the decrypted images and documents, but still be unusable.
Doing the same with a XLS, after two days doesn't found the key.
HEX comparing the ciphered and unciphered I see that the ciphered part is the first 100000 bytes also append to the EOF many other bytes. 
Here an example of one file ciphered and plain useful fo testing:
Some other have got this kind of the new ransomware ?
Thanks in advance for who can help us.

Yes it is a ransomware similar to fud@india.com, helpme@freespeechmail.org and several other *****@******.com variants.

It is believed these infections are part of a ransomware kit that different affiliates utilize with their own payment email addresses which explains all the "@" ransomwares which have been reported. In some cases encrypted files will have the {CRYPTENDBLACKDC} extension appended to the end of the filename.

There are going discussions in these related topics where you can ask questions and seek further assistance.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.
