Why TeslaCrypt is considered one of the most dangerous ransomware out there?

TeslaCrypt is a malicious computer program, which is a ransomware type malware. This virus spreads every day, and although the TeslaCrypt decrypt tools for some versions of it were already released, users who are unaware of that still pay the ransoms to the cyber criminals. Frauds who spread Tesla Crypt aim to attack small businesses and online companies. It has already increased its distribution rate from 200 to almost 2000 infected PC systems per day, so be sure that you are careful when browsing the Internet. Also, make sure that you have a reputable anti-spyware installed on your computer and keep it up-to-date to prevent TeslaCrypt ransomware.

Similarly to its predecessors Cryptowall, Cryptolocker, Simplelocker and Threat Finder, TeslaCrypt arrives at the system with the help of spam. Once it drops its files onto the target computer, it checks it for sensitive information, such as specific files, business documents, videos, pictures, and similar data. Beware that Tesla Crypt virus can also try to encrypt your games and their files. It is known that it has already affected PC users who were playing World of Tanks, World of Warcraft, StarCraft, MineCraft, Dragon Age, RPG Maker, and Steam. It is known that for disabling its victims from the use of their data, this ransomware uses a strong algorithm known as AES encryption. As a result, all extensions of affected files are changed to .vvv, .ccc and similar extensions.

For letting its victim know that he or she was affected by TeslaCrypt ransomware, it creates a file called howto_recover_file.txt. If you are infected, you should be capable of finding it on your computer's desktop. Typically, this notification claims that the user has to pay a fine of $500 or even $1000 in exchange for the decryption key that is needed to unblock the affected information. This payment should be sent via PayPal My Cash cards using TOR browser. That's how the developers of Tesla Crypt virus that are still unknown for governmental authorities are trying to hide. Victims can pay their ransoms in a form of Bitcoins and PayPal. However, for those who are using this payment system, the ransom is increased twice.

Warning messages that are caused by TeslaCrypt ransomware

TeslaCrypt virus distribution techniques:

According to the latest reports, you can get infected with TeslaCrypt virus with the help of misleading email messages that have an attachment called invoice_2h04qd.js. Such emails claim that you were approved for special prices, just as you requested. The subject line claims 'Required your attention'. Please, do NOT open such message and do NOT download this attachment to your computer. No matter how tempting it looks, all what it seeks is to infect your computer with TeslaCrypt. Of course, there is no guarantee that you won't run into other campaign used for distributing this ransomware. That's why you should always check the sender and, if you don't know it well, remove such email message from your inbox.

Other TeslaCrypt versions:

TeslaCrypt 2.0 is a dangerous ransomware-type application capable of encrypting files on the infected PC system. It does that with the help of an ECHD algorithm that creates a different master key for each of infected computers. All extensions of files encrypted by TeslaCrypt 2.0 are changed to .VVV. The text of a warning message is the same as the one that is used by CryptoWall virus, so it claims that the victim has to pay 500 USD or euros for decrypting encrypted files. Unfortunately, but there is no guarantee that this will help you to get your files back. It would be wiser to remove TeslaCrypt 2.0 and restore affected files with the help of their extra copies.

  • .vvv File Extension virus. After infecting the system and encrypting useful files, it changes their extensions to .vvv and drops HOW_RECOVER.HTML, HELP_RESTORE.HTML, HOW_RECOVER.TXT or HELP_RESTORE.TXT document on the desktop. According to it, the victim has to pay the ransom for getting an ability to use his/hers files again. Please, do NOT pay it because you can lose your money.

The initial and the second version of TeslaCrypt use the same key to encrypt and also to decrypt the files, and after the decryption process, these viruses leave specific traces that can help the user to find the decryption key. Besides, using the flaw in the program code of these viruses, some security experts have already invented some TeslaCrypt and TeslaCrypt 2.0 decryption tools that can help you to decrypt your files.

TeslaCrypt 3.0 version has its flaw patched and after the virus encrypts the files, it deletes the decryption key from the computer. As a result, it becomes much harder to recover the lost data. TeslaCrypt third edition demands more than 400 USD dollars in exchange for a decryption key.

  • .ccc File Extension virus is also known as a seriously dangerous application that seeks to disable its victim from opening his/hers files. It does that by encrypting them with an advanced encryption technology. As a result, all extensions of important files are turned into .ccc. If you can't open your files and you can see such extensions, there is a huge possibility that you are infected with .ccc File Extension ransomware. In this case, you should remove infected files of .ccc File Extension virus to prevent the further loss of your files.
  • .xxx File Extension virus - this version of TeslaCrypt 3 also makes victim's files inaccessible and embeds .xxx extension to the filenames of affected victim's records. If you see that these extensions were added to your files, it is a sign that you cannot access them anymore. The price for a .xxx File Extension virus decryption tool is around 400 dollars as well. Unfortunately, we do not recommend you to pay up because you might not receive the decryption tool at all.
  • .ttt File Extension virus - the appearance of .ttt file extensions unexpectedly added to the filenames on your computer reveals the existence of the third version of TeslaCrypt virus. Just like other variants of TeslaCrypt 3.0 (.xxx, .micro, .ccc file extension viruses), .ttt File Extension virus commands to pay for the decryption key. Unfortunately, there is no guarantee that cybercriminals will give you the decryption key if you pay up.
  • .micro File Extension virus is a version of third TeslaCrypt variant. After encrypting victim's files, it adds .micro file extension to their filenames. The ransom demanded by cybercriminals is also equal to approximately 400 USD. It acts the same as any other TeslaCrypt 3.0 variant.

TeslaCrypt 4.0 is regarded as the most advanced variant of that virus. This virus no longer adds additional file extensions to the filenames. It also uses a complex encryption algorithm - RSA-4096. TeslaCrypt 4.0 drops ransom notes titled as RECOVER[5 random symbols].html. Unfortunately, the encryption algorithm this malware uses is nearly unbreakable, so you must take precautions and secure your files in case your computer gets affected by this virus. You should read this article - Why do I need backup and what options do I have for that?

TeslaCrypt 4.1b is currently the latest version of the TeslaCrypt virus. The researchers are still finding out new features which have been added to this newest edition. So far, it seems that the encryption process and the amount of ransom demanded in exchange to the encrypted files has not undergone any changes. Yet, new gateways were added to the list of websites where the victims can issue payments for their files. It was also found that this virus uses WMIC (Windows Management Instrumentation Command-line) to delete the shadow copies of the files on the PC so that it would be impossible for the user to restore these files from the system backup. In general, the differenced of this program in comparison to its predecessors are slight.

How to remove TeslaCrypt virus and decrypt your files?

If you can see this warning message when trying to open your files, you are infected:

Your files have been safely encrypted on this PC: photos, videos, documents, etc. Click "Show encrypted files" Button to view a complete list of encrypted files, and you can personally verify this.
Encryption was produced using a unique public key RSA-2048 generated for this computer. To decrypt files you need to obtain the private key.
The only copy of the private key, which allow you to decrypt your files, is located on a secret server in the Internet; the server will eliminate the key after a time period specified in this window.
Once this has been done, nobody will ever be able to restore files...
At the time of research, the TeslaCrypt virus distribution method was unknown, however, following successful infiltration on computer systems, the software scans all drives and encrypts certain file types using AES encryption. Encrypted files will have the .ecc extension applied to the filename.

If this threat has already infected your computer and encrypted your data, you need to perform the following tasks:

  • Disconnect your computer from the Internet;
  • Run a full system scan with Reimage and remove infected files from your computer;
  • UPDATE. TeslaCrypt project was shut down in May, 2016. Cyber criminals have revealed master key that allows victims decrypt their files for free. If your files are encrypted by Teslacrypt, use this TeslaCrypt decryption tool to recover them.
