Sext ransomware – new cryptovirus demanding $600 worth of Bitcoins for the decryption tool

Sext ransomwareSext ransomware is a computer infection that renders your files useless until ransom of $600 is paid

Sext ransomware is a newly created cryptovirus that completely locks all personal files on the infected device. This virus encrypts all data with a very strong RSA algorithm[1]. All non-system files are appended with a .sext extension, hence the name of the ransomware. With this cryptovirus, a new lineage of LockDown ransomware family has been started.

After the Sext ransomware has finished encrypting files, it creates ransom notes, named HELP_DECRYPT_YOUR_FILES.txt. Within these notes, cybercriminals are reassuring the victims that they can retrieve their files, for a payment of $600. The ransom must be forwarded to the perpetrators in cryptocurrency Bitcoin to their crypto-wallet – 15zw6QrCbd5r8CD2eySMoTktstuEgD1Dzs. As in most ransomware, like FUSION or Termit, developers of this virus want to prove that they really do have the necessary decoding tool/key, and offer to send them one file for a test decryption. Victims are required to contact the criminals via email – getyourdata@protonmail.com with their unique assigned personal ID.

System fix Use a powerful ReimageIntego tool after the sext virus removal to tune-up your system and avoid hazardous PC behavior

Based on statistics from VirusTotal.com[2], 55 out of 72 anti-virus engines detected this cryptovirus before it infected the computer systems. This shows the importance of reliable anti-malware software like Malwarebytes or SpyHunter 5Combo Cleaner. Use any of these apps to automatically and completely remove Sext ransomware from your contaminated device.

However, Sext ransomware removal won't decrypt your files. Nonetheless, it is still highly inadvisable to get in touch with the cybercriminals or even worse – complying with their demands. People not only lose their data but their money too. Experts[3] advise deleting the virus immediately and fixing any system settings and system file issues with a mighty system tune-up ReimageIntego tool. Only then start restoring your data from backups and fully using your virus-free systems.

The whole criminal ransom note in files HELP_DECRYPT_YOUR_FILES.txt reads:

Oops All Of your important files were encrypted Like document pictures videos etc..

Don't worry, you can return all your files!
All your files, documents, photos, databases and other important files are encrypted by a strond encryption.

How to recover files?
RSA is a asymetric cryptographic algorithm, you need one key for encryption and one key for decryption so you
need private key to recover your files. It's not possible to recover files without private key.
The only method of recovering files is to purchase an unique private key. Only we can give you this key and only

Techniques used by criminals to contaminate computers

Cybercriminals are trying really hard to outsmart everyday computer users, or catch them “sleeping”. They are using the same methods to spread their malicious creations for years now. People should be more careful while doing these things:

  • Opening any emails, especially from the spam folder. During spam campaigns, cybercriminals send out tens of thousands of emails with mischievous hyperlinks and infectious attachments. Never open phony looking hyperlinks. Always scan email attachments with a proper anti-virus app before opening or downloading them.
  • Visiting file-sharing platforms, like The Pirate Bay, BitTorrent, and others. A harmlessly looking crack (aka software illegal activation tool), or some game cheat codes, or anything else on those sites, might actually be malware in disguise. And right after it gets entry to a computer system it starts its dirty deeds.

To stay safe on the internet all users, no matter how tech-savvy, should always have their backs watched by some trustworthy anti-malware software. 

Guidelines for Sext ransomware removal and system restore

As mentioned in the first paragraph, users should focus on this virus' elimination from the infected system.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Sext from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If your files are encrypted by Sext, you can use several methods to restore them:

Make use of Data Recovery Pro

Data Recovery Pro is designed to recover files that were accidentally deleted or lost due to hard drive wipe. However, the program also proved to be useful for some ransomware victims.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Sext ransomware;
  • Restore them.

When attempting to recover from a ransomware attack, try Windows Previous versions

This method might be useful if malware did not delete Shadow Copies, and you had the System Restore feature enabled.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

ShadowExplorer can automate data recovery process

If the virus did not perform its actions correctly, ShadowExplorer should be able to help you.

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

No decryptor is is currently available

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Sext and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

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.
