Crypto-Blocker ransomware is blackmailing people and threatening to damage their computers

Crypto-Blocker is a new file-encrypting virus that uses AES[1] ciphers to make files on the targeted computer inaccessible. Malware appends .corrupted file extension to encrypted files and delivers a ransom note on the lock screen. The ransom-demanding message informs about necessity to pay 10 euros, dollars or pounds within 5 hours. Otherwise, affected computer might crash. However, if you see this threatening message, you should not panic and focus on Crypto-Blocker removal. Cyber criminals often use psychological terror to make people pay the ransom. Though, they usually are unable to damage the device or delete encrypted files. However, you should not waste your time and employ professional malware removal program. We suggest scanning your device with Reimage and remove Crypto-Blocker with the help of it.

Ransom note delivered by Crypto-Blocker

In the ransom note, developers of the Crypto-Blocker ransomware presents themselves as the “hacker company.” These shady people use a vivid language to scare victims. The threatening message informs that if users want to keep their computers “alive” they need to pay 10 euros, dollars or pounds. However, hackers are understanding and allow victims to choose other currency if they need to pay the ransom. Indeed, it’s unusual behavior because crooks often are strict about ransoms. However, they give a short amount of time to make the payment – only 5 hours. Once victims transfer the money, they receive a code that they need to enter into the box at the bottom of the lock screen. Then, all their files should be decrypted, and Crypto-Blocker deleted from the system. Otherwise, people might face even more problems. According to the crooks, if they will not receive a ransom on time, the affected computer might crash or become “unusable.” Undoubtedly, the payment is small, and you might feel that it’s worth to take the risk. However, we do not recommend spending such money and sponsoring further cyber crimes. Even one dollar is a motivation for cyber criminals to work harder and create bigger illegal projects, and your files might be still left encrypted.

Ransomware distribution and infiltration strategies

It’s unknown what specific technique is used for the circulation of Crypto-Blocker virus. Probably, cyber criminals use traditional ways to spread it, for instance, malicious spam emails, malvertising,[2] fake updates, and exploit kits. Thus, if you want to avoid ransomware, you should take precautions, make data backups and be careful when browsing the Web. First of all, do not rush opening attachments or clicking links (or buttons) provided in the unknown email. Crooks might send emails where they pretend to be from banks, online shops and other reputable companies or organizations, and easily trick you into opening an infected content. Crypto-Blocker might be installed on the device as soon as you click on obfuscated word or pdf document, amazing shopping offer or any online ad. Bear in mind that this content might look legitimate and safe, so you should be critical and do not take any harsh actions. Finally, you should keep your software updated and strengthen your computer’s security with professional security program.

Deleting Crypto-Blocker ransomware virus from the computer

We recommend victims to remove Crypto-Blocker as soon as they receive a ransom demanding message. Virus elimination is completed using a powerful malware removal programs, such as Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware. However, you might not be able to install such programs easily. Malware might prevent you from simply downloading it.
