TeslaCrypt 4.0 Removal Guide

What is TeslaCrypt 4.0?

TeslaCrypt 4.0 virus is yet another version of well-known file locking ransomware

TeslaCrypt 4.0 virus is another version of TeslaCrypt ransomware. Like most threats of this kind, this ransomware encrypts confidential information and delivers a note requiring to pay the ransom in exchange for the encrypted data. It has been reported that the malware came with some updated features and fixes. Therefore, we are here to inform you about them and the options that you have after being infected with this threat.

As we have already mentioned, TeslaCrypt 4.0 ransomware is a renewed version of TeslaCrypt, which was noticed more than a few years ago. However, it seems that the creators of this virus decided to make things worse by fixing a bug that was noticed in previous versions.

TeslaCrypt 4.0 no longer attaches an extension to the encrypted files, so you can not even know that your files are locked. Moreover, earlier the virus had a bug that corrupted files bigger than 4 GB, however, now this bug is fixed and the virus is able to encrypt all files without corrupting them. When it finishes the encryption process, it leaves these files on your system:

  • Desktop: RECOVER[5_chars].html
  • Desktop: RECOVER[5_chars].png
  • Desktop: RECOVER[5_chars].txt
  • Documents: recover_file.txt
  • Documents: [random].exe

Additionally, it seems that the latest version of TeslaCrypt uses a different encryption algorithm – RSA 4096, contrary to widely used RSA 2048 code.

If this virus has already affected your files and you are looking for the decryption software, do not rush to search for your credit card. It is possible to decrypt TeslaCrypt without paying the ransom. Look for decryption software at the bottom of this article.

Ransomware spreads in different ways

Though it is known that there are new features added to this ransomware, the main principle remains the same. You can get infected with this ransomware via spam containing a malicious attachment. Once you open it, the virus starts encrypting your files. Further on, it generates two keys for the encrypted data – a private and public key. The public key enables anyone to decrypt the files in other systems, but, in order to access it again, a unique private key is created. Thus, you need to acquire two different keys to retrieve your valuable information.

What is more, cybercriminals try to make a victim lose his or her temper by providing seemingly simple solutions. Certainly, all of them are seeking the same goal – trick users into thinking that paying the ransom is the only choice to retrieve the data. Nonetheless, do not behave according to their expectations and think about virus removal instead.

If you have too much money, you might try to make a transaction and hope that cybercriminals will have mercy on you. However, it is unlikely. Furthermore, beware that the virus targets computers via exploit kits, alternatively known as trojans. These files have the ability to pass themselves off as ordinary system files. Thus, when they infiltrate a system, they set free ominous ransomware.

As you can see, the consequences are significantly damaging. If you are one of the unlucky ones who have been affected by ransomware, check below to know more about its removal.

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
