What is TeslaCrypt 4.2?

TeslaCrypt 4.2 virus: updated and more aggressive

If you haven’t heard about the newest version of TeslaCrypt – TeslaCrypt 4.2 virus – then we are glad to enlighten about this new sample of ransomware. This particular threat is programmed for a hideous task – to encrypt personal data and require a ransom in exchange for it. This family of viruses has already built up enough experience of hijacking computers, since hackers restlessly create new versions. It is not expected that this virus will be less treacherous or less damaging. Cyber criminals only introduced minor new features. One of them is the changed design of ransom note. If you happen to get in to the victim list, then it is crucial to remove TeslaCrypt 4.2 virus as soon as possible.

If we take a look at general history of the malware, the virus started off as a relatively minor ransomware version infecting gamers’ computers. The decryption key might have been found in the system. Thus, it didn’t cause major problems. Within time, cyber criminals have improved significantly. The previous version TeslaCrypt 4.0 version uses an elaborate encryption algorithm. Moreover, it didn’t attach any extensions to the encrypted files. Thus, detecting the virus itself became a challenge. Speaking of current version, TeslaCrypt 4.2 ransomware, leaves these files:

Moreover, the size of the file with recovery instructions has been changed from 256B to 272 bytes. The virus also injects C:\Windows\System32\vssadmin.exe. In comparison with older versions, the current malware deletes copies of the locked files as well.

The distribution ways of TeslaCrypt 4.2 malware

The virus disperses the same way as previous versions. It can infect computers via spam email attachments. In relation, cyber criminals are especially crafty at this. They convince victims into opening an infected email by deceiving them with false invoice notifications, alerts which look like to be sent from governmental institutions. Thus, once users open it, the virus extracts itself.

Moreover, it seems that hackers didn’t try to leave an impression in creating a dramatic design of the ransom note. The file which is entitled as -!recover!-!file!-.txt looks like an ordinary Notepad text file informing of the locked files and providing instructions to recover the encrypted files. Hackers deliver the links to access Tor browser to remit the payment. If your computer was targeted as well, do not foster any hopes to get the data back. From the beginning when the first version was released, cyber criminals have managed to collect a terrific amount of money. However, in May 2016, authors of TeslaCrypt virus shut down the project and released the decryption key, so now you can recover your files for free. Go to page 2 to find out how to recover your files.

Furthermore, you should be aware that TeslaCrypt 4.2 might attack PCs via exploit kits as well. They might come in a different forms: trojans, worms, Java script files. Particularly trojans have an ability to slip into the system without getting stopped by anti-virus software. Thus, it is crucial to have a powerful anti-spyware program. Now let us proceed to TeslaCrypt 4.2 removal. You can use FortectIntego for that.

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.
