TeslaCrypt, also known as AlphaCrypt, Cryptesla, and Tescrypt is one of the most prevalent crypto viruses (or ransomware) at the moment, the other one being CryptoWall. Recently, we witnessed a freshly updated version of TeslaCrypt.
This version was encrypting the user’s files, appending a .vvv extension to them and adding how_recover+abc files in multiple folders. Just a few weeks later, we’re already witnessing another updated version of TeslaCrypt’s .vvv variant, using even stronger encryption – RSA-4096.
Threat Summary
Name
TeslaCrypt RSA-4096
Type
Ransomware
Short Description
A new version of TeslaCrypt has employed the RSA-4096 algorithm.
Symptoms
The .vvv extendion is appended to the victim’s files.
Distribution Method
Via exploit kits, suspicious emails, etc.
Detection Tool
See If Your System Has Been Affected by TeslaCrypt RSA-4096
Windows Data Recovery by Stellar Phoenix Notice! This product scans your drive sectors to recover lost files and it may not recover 100% of the encrypted files, but only few of them, depending on the situation and whether or not you have reformatted your drive.
Let’s call this new version of the rasomware TeslaCrypt RSA-4096. What is the difference between the previous known version and this one? Basically, the main change is in the encryption key. The latest version of TeslaCrypt has adopted an encryption algorithm known to be practically impossible to decrypt. The decryption process of RSA-4096 would take hundreds, maybe thousands of years to decrypt, even with the assistance of a super computer.
BleepingComputer has classified all the variants of TeslaCrypt in accordance with the file extensions they append to the victim’s files.
Here is the list:
TeslaCrypt Version 1
Extension – adds .ecc extension Decryption – yes, with the help of TeslaDecoder
TeslaCrypt Version 2
Extension – .ecc Decryption – yes, with the help of TeslaDecoder
N.B. With these versions of TeslaCrypt decryption is possible in cases when the decryption key was zeroed out but partial key was still available in key.dat. Moreover, the decryption key could also be obtained from TeslaCrypt’s request sent to the server. This ‘mistake’ was fixed with the next version.
TeslaCrypt Version 3
Extension – adds .ecc, .ezz extensions Decryption – yes, with the help of TeslaDecoder
N.B. With this version, it’s already impossible to recover the original decrypton key without the private key only known by the ransomware’s authors. However, decryption key could be obtained from TeslaCrypt’s request to the server.
TeslaCrypt Version 4
Extension– adds .ezz, .exx extensions Decryption – yes, with the help of TeslaDecoder
N.B. With this version, it’s again impossible to recover the original decrypton key without the private key only known by the ransomware’s authors. However, decryption key could be obtained from TeslaCrypt’s request to its server.
TeslaCrypt Version 5
Extension – adds .xyz, .zzz, .aaa, .abc, .ccc extensions Decryption – only possible if the victim succeeded in capturing the key while being sent to the server at the time of encryption.
TeslaCrypt Version 6
Extension – adds .xyz, .zzz, .aaa, .abc, .ccc extensions Decryption – no known way to decrypt the files without the decryption key sent by the ransomware’s authors; only possible if the victim succeeded in capturing the key while being sent to the server at the time of encryption.
TeslaCrypt Version 7
Extension – adds .ccc extension Decryption – decryption is only possible, if the victim succeeded in capturing the key during the encryption process in the memory of the machine.
TeslaCrypt Version 8
Extension – adds .vvv extension Decryption – decryption is only possible, if the victim succeeded in capturing the key during the encryption process in the memory of the machine.
TeslaCrypt RSA-4096 Version
As already mentioned, this updated version of TeslaCrypt appends the .vvv extension to the victim’s files.
Victims of the ransomware have reported that their files have been changed to ‘[file name].docx.vvv’. Also, how_recover+nsv.html and how_recover+nsv.txt files are dropped in every folder.
The Trojan dropping the ransomware has been detected to be Trojan:Win32/Miuref:B – an infostealer type of Trojan. Other Trojans may be used in the malicious operation as well.
It’s also important to note that the main executable files that are responsible for the encryption process were most likely deleted after completion of encryption. Also, once TeslaCrypt has finished encrypting the victim’s files, it typically deletes itself. The only traces left are the ransom notes. If an AV program is present on the victim’s system, it should have cleaned off any leftovers of the ransomware.
According to the November update article by Microsoft’s Technet, Microsoft Malicious Software Removal Tool should be updated and able to detect TeslaCrypt. Microsoft’s detection names for TeslaCrypt are Tescrypt, Win32/Tescrypt, Ransom:Win32/Tescrypt.
However, no AV program released by Microsoft or another vendor is able to decrypt files encrypted by ransomware. For now.
What Should Users Attacked by TeslaCrypt RSA-4096 Do?
Unfortunately, files encrypted with the strong RSA-4096 algorithm cannot be decrypted, except when a decryption key sent by the ransomware’s authors is used. As you probably know, security researchers never advise on paying the demanded ransom. Ransomware has evolved so much because cyber crime groups have gathered enough resources and were able to improve their products.
The only way to decrypt your files (besides paying for the decryption key) is if you have an external backup that was kept offline.
Once you have removed the threat via an anti-malware program or manually, you can use your backup solutions to restore the encrypted files. However, if you haven’t regularly backed up your files, nothing can be done.
Encryption by earlier versions of TeslaCrypt could be broken because these versions stored the private key on the local disk. Decryption could also be done via Cisco’s Talos Group Decryptor and TeslaDecoder. However, later versions were improved and ‘mistakes’ made by earlier versions were fixed. TeslaCrypt RSA-4096, in particular, has used an encryption so strong that it could take years for a super computer to decipher the encrypted information.
Is There Any Protection against Ransomware?
Besides sustaining a strong anti-malware program and all the ‘classical’ protection methods to guard the system (combination of anti-malware and anti-virus, external firewall, etc.), there are some tools such as Shadow Defender designed to protect against ransomware such as TeslaCrypt RSA-4096.
What Is Shadow Defender?
Shadow Defender is a security solution for Windows systems. The tool can run in a virtual environment called Shadow Mode which redirects each system change to a virtual environment with no change to the real one. The virtual environment is also known as Light Virtualization. In other words, Shadow Defender can restore the system to its original state, or before the particular infection took place. We haven’t tested the solution, so we cannot confirm that it works on ransomware cases. However, users who have tried it have shared positive opinions. The only weak spot of the solution appears to be rootkit-related. The operator of the rootkit could disable the tool or delete its databases, stripping it from its capability to restore the system to an uninfected state.
Finally, if you have been hit by TeslaCrypt RSA-4096 or another ransomware and you haven’t cleaned your system, refer to the removal options below the article.
You can also refer to our forum where you can start a topic and receive help.

Step 5 (Optional): Try to Restore Files Encrypted by TeslaCrypt RSA-4096.
Ransomware infections and TeslaCrypt RSA-4096 aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that these methods may not be 100% effective but may also help you a little or a lot in different situations.
Method 1: Scanning your drive’s sectors by using Data Recovery software. Another method for restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:
Method 2: Trying Kaspersky and EmsiSoft’s decryptors. If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:
To restore your data in case you have backup set up, it is important to check for Volume Shadow Copies, if ransomware has not deleted them, in Windows using the below software:
Method 4: Finding the decryption key while the cryptovirus sends it over a network via a sniffing tool.
Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:

Bonjour, à tous ! Mes fichiers ont été cryptés en RSA-4096, mais ce n’est pas TeslaCrypt… On m’a demandé une rançon…Il y a quelqu’un qui a payé déjà ? Tout c’était bien passé ? Merci !
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) […]
L’extension est “vvv”.
Quelqu’un qui s’y connait a essayé de récupérer mes fichiers, mais il n’a pas arrivé…D’après lui, c’est une nouvelle version du CryptoWall
Je ne sais pas comment le virus a infecté le PC…je n’ai pas ouvert des emails et je ne pas navigué sur des sites douteux. J’ai scanné le PC et les outils utilisés n’ont rien trouvé…
Pour moi, maintenant est important de récupérer les fichiers ; c’est pour cela que j’ai demandé si quelqu’un a payé la rançon…le délai accordé approche…
We believe that the ransomware is TeslaCrypt. TeslaCrypt has used the .vvv extensions before.
TeslaCrypt or CryptoWall, RSA-4096 encryption is very difficult (close to impossible) to decrypt. Has your friend tried any decryptor tools such as TeslaDecoder? Do you have a clean backup of your files?
Re-bonjour, Oui, on a essayé TeslaDecoder, mais sans succès..il ne s’agit pas de Teslacrypt, d’après lui.. Au début, il a eu la même opinion…que c’était Teslacrypt, mais après la vérification avec TeslaDecoder, il s’est rendu compte que ce n’était pas Teslacrypt. Non, je n’ai aucun backup…c’est pour cela que je prends en calcul de payer la rançon…c’est vrai que je n’ai pas pris une décision, mais c’est la seule possibilité de récupérer mes dossiers. Merci !
