Hi,

 

Some PC from my workplace were hit by this kind of ransomware - Trojan-Ransom.Win32.Rakhni, wich I think I get rid of it but my office files and pdf's are now encrypted. I run the Rakhni Decryptor from Kaspersky twice 3-4 days each time and gived me nothing - Found: 0; Decrypted: 0.

 

What should I do to recover/decrypt  my files?

 

 

P.S.:  I couldn't  attach the encrypted file with the name and extension it was renamed by ransomware, not even in a rar archive. The Rakhni ransomware  it gived to this file the name:

 

programa pentru simularea din decembrie 2015 la BAC la geografie.pdf.id-4775085215_helpme@freespeechmail.org     <<< modified by Rakhni Ransomware

 

In the attachment you will find the original name +extension of the file, the same as was created by author but the file is ecrypted by  Rakhni.

 

Please help.

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.

Kaspersky Lab has a utility called RakhniDecryptor that is able to brute force the decryption key for the helpme@freespeechmail.org ransomware and other <filename>.<original_extension>.<"@" variants.

For more information and instructions for using RakhniDecryptor, please refer to this BC news article...There are going discussions in these related topics.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
