removal by Julie Splinters - - | Type: Ransomware

TBlocker – ransomware virus that locks the affected computer

Ransom note by TBlocker ransomware

TBlocker is a crypto-virus that can encrypt files and lock the computer. Malware displays a threatening lock-screen message where victims are demanded to pay $250 in Bitcoins in 24 hours. Criminals use psychological terror to scare victims by telling that their files will be published online and the computer gets locked forever.

TBlocker ransomware has been spotted spreading in February 2018. Developers of ransomware seem to be using malspam as the main way to infect devices. The TBlocker.exe file is dropped on the system as soon as a user gets tricked by clever social engineering[1] scheme and opens the attached file. Once inside, it starts acting as a regular file-encrypting virus:

  • alters Windows registry in order to boot with system startup;
  • inject malicious codes into important system processes;
  • install many executables to perform various tasks on the system;
  • encrypt files;
  • might delete Shadow Volume Copies[2] to make data recovery nearly impossible.

Once TBlocker virus finishes all above mentioned tasks, it delivers a ransom note in lock screen window. The message tells:

Ooooops!!
Device blocked by TBlocker

All your files have been encrypted with a key that we only have.
If you want to retrieve the files pay by bitcoin to:
[bitcoin wallet address redacted] the sum of $ 250.
The system has been compromised, it is not possible to exit.

Time Left: [Timer counts down the time]

At the expiration of time all your files will be made public on the internet
and the PC will be permanently locked.

However, you should not be threatened by TBlocker ransomware virus. It’s possible to get back access to your device, and you should do it immediately by cleaning your PC with Reimage or another malware removal tool.

Unfortunately, data decryption might be complicated or even impossible unless you have data backups. Security programs can only remove TBlocker from the system, but they cannot recover damaged files. For that, you can try third-party tools we offered below the article.

Keep in mind that TBlocker removal should be completed first. While ransomware resides on the system, you won’t be able to use your PC normally and safely. You can find more information about virus elimination at the end of virus description.

Watch our for dangerous emails

The biggest chances to catch a ransomware virus is to open a malicious email attachment. Malware might be included in any Word, Excel, PDF or similar safe-looking file. Hence, you have to make sure that you can actually trust the sender and the added document is real first.

However, researchers from LosVirus.es[3] tell that authors of ransomware might be using other methods to spread their malicious program, such as:

  • malvertising,
  • fake software downloads or updates;
  • drive-by downloads;
  • brute-force attacks.

Hence, you should follow general cyber security tips, install a reputable antivirus program and be prepared for ransomware attack by creating data backups.
