Hi,

My computer got infected;( I would be very grateful if anyone could help me.

 

I have ASUS (Windows 8.1). There is a .vvv file extension appended to my files. In every folder are also 2 files: how_recover+nsv.html and how_recover+nsv.txt

 

I downloaded Microsoft Safety Scanner from the other PC, and run full system scan in safe mode without internet connection. It detected and removed Trojan:Win32/Miuref:B - when the scan was completed the window popped up with the link to this site http://www.microsoft.com/security/portal/threat/encyclopedia/entry.aspx?name=Trojan%3aWin32%2fMiuref.B#tab=2

 

Jsssssssss from Microsoft forum says it's a newer variant of TeslaCrypt/Alpha Crypt - http://answers.microsoft.com/en-us/protect/forum/protect_defender-protect_scanning/i-have-been-infected-with-a-malware-which-encrypt/77b05496-fb09-4e01-ab36-db92213dd825?auth=1

 

I had no luck with decrypting files:( When I start the computer a notepad pops up with this message:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

NOT YOUR LANGUAGE? USE https://translate.google.com

What happened to your files ?
All of your files were protected by a strong encryption with RSA-4096.
More information about the encryption keys using RSA-4096 can be found here: http://en.wikipedia.org/wiki/RSA_(cryptosystem)

How did this happen ?
!!! Specially for your PC was generated personal RSA-4096 KEY, both public and private.
!!! ALL YOUR FILES were encrypted with the public key, which has been transferred to your computer via the Internet.
Decrypting of your files is only possible with the help of the private key and decrypt program, which is on our secret server.

What do I do ?
So, there are two ways you can choose: wait for a miracle and get your price doubled, or start obtaining BTC NOW, and restore your data easy way.
If You have really valuable data, you better not waste your time, because there is no other way to get your files, except make a payment.

For more specific instructions, please visit your personal home page, there are a few different addresses pointing to your page below:

If for some reasons the addresses are not available, follow these steps:
1. Download and install<Removed>
2. After a successful installation, run the browser and wait for initialization.
3. Type in the address bar:<Removed>
4. Follow the instructions on the site.

I have recently been working with this Tesla, which is apaprently simialar and/or related to CryptoLocker/Wall Virus, same

tactic as ransomware in general.

Welcome to BC

Any files that are encrypted with the newer variant of TeslaCrypt will have the .exx, .xyz, .zzz, .aaa, .abc, .ccc or .vvv extension appended to the end of the filename. The .aaa/.abc/.ccc/.vvv variants leave .html, .txt, files (ransom notes) with names like RECOVERY_FILE_*****.txt, restore_files_*****.txt, recover_file_*****.txt, Howto_RESTORE_FILES_*****.txt, howto_recover_file_*****.txt, _how_recover_*****.txt, how_recover+***.txt (where * are random characters).A repository of all current knowledge regarding TeslaCrypt, Alpha Crypt and newer variants is provided by Grinler (aka Lawrence Abrams), in this topic: TeslaCrypt and Alpha Crypt Ransomware Information Guide and FAQ

Information about and support for decrypting files affected by Alpha Crypt & TeslaCrypt ransomware can be found in this topic:Since v5 there is no way to decrypt the newer TeslaCrypt variants (.xyz, .zzz, .aaa, .abc, .ccc, .vvv) without Tesla's private key or a purchased decryption key. It is no longer possible to get the encryption key from Tesla's request without Tesla's private key...since there is no private key anymore, it can't be used to decrypt files. See here for possible decryption information with each version.

There is an ongoing discussion in this topic 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 that topic discussion. 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
