Types of Ransomware

There are two types of ransomware in circulation:

  1. Encrypting ransomware, which incorporates advanced encryption algorithms. It’s designed to block system files and demand payment to provide the victim with the key that can decrypt the  blocked content. Examples include CryptoLockerLockyCrytpoWall and more.
  2. Locker ransomware, which locks the victim out of the operating system, making it impossible to access the desktop and any apps or files. The files are not encrypted in this case, but the attackers still ask for a ransom to unlock the infected computer. Examples include the police-themed ransomware or Winlocker.

Some locker versions can even infect the Master Boot Record (MBR). The MBR is the section of a PC’s hard drive which enables the operating system to boot up.

B0r0nt0k Ransomware

Technically, ransomware has been prevalent since the 90s, but in the past five years, it has taken off. The main reason behind its immense acknowledgment is owing to the availability of untraceable payment methods such as Bitcoin. Here are some of the major ones –

CryptoLocker –

Launched in 2013 and infecting 500,000 machines, this is a type of Trojan ransomware. It spreads through compromised email attachments or via a botnet. When this ransomware is downloaded and activated, it goes ahead and searches for particular types of files to encrypt.

This encryption is carried out with the help of RSA public key cryptography; then it sends the private key to some distant servers. It further demands the owner of the system to pay ransom to decrypt or recover the affected files. In case the owner fails to do so, he loses the private key.


This ransomware is a file-locking virus. This virus encrypts the files on the linux server and marks them with .rontok file extension. This is, indeed, a serious cyber infection that affects not just your data but it goes one step ahead and makes changes to –

  •      Modified startup settings
  •      Added registry entries
  •      Added files or programs
  •      Disabled functions or applications

TeslaCrypt –

This is also a type of ransomware and mainly targeted gaming files. This one encrypts the files saved on the machine, and a ransom is demanded to attain the decryption key. With the help of decryption key, normal access to the affected files can be gained.

SimpleLocker –

This ransomware, popular in late 2015 and early 2016, attack mainly affected mobile phones. This ransomware also encrypts the files, making it inaccessible without the assistance of the scammer.

WannaCry –

Also known as WannaCrypt, WannaCryptor, and Wanna Decryptor, WannaCry is yet another type of ransomware. This particular ransomware will seal your device (personal computer, tablet, or a smartphone) infect your files and a message will be displayed seeking ransom.

As a victim, you will be asked to pay a ransom via Bitcoin. The files will only be released once the scammer has received the payment, however failing to pay the amount will lead to the destruction of the data. On the negative side, paying the ransom does not ensure recovery of the encrypted data.

NotPetya –

In 2017, just weeks after the outbreak of WannaCry, NotPetya infected thousands of computers in over 100 nations in just a matter of days. This malware also used the same exploit WannaCry used. This particular ransomware is unlike other ransomware where the primary motive was to cause disruption.

Locky –

Released in 2016, this ransomware was discovered by the IT experts. The scammers used to send infected emails appealing for payment via an invoice as a malicious Microsoft Word document that runs infected macros.

As and when the user opens the document, he/she receives a pop up saying “Enable macro if data is incorrect,” which is a standard method to deceit the user and simultaneously affect the system.

A cryptovirus like B0r0nt0k can disable security tools or other functions to keep running without interruption, warns 2-Spyware.com. The B0r0nt0k ransomware can alter more crucial parts of the computer if left untreated.

While it may not be currently clear how the B0r0nt0K ransomware was able to establish a foothold on the affected Linux servers in question, typically it comes back to server misconfigurations or from running out-of-date versions of software with known remote code execution vulnerabilities

Take Backups

Ransomware attacks like B0r0nt0K prey on organizations that lack preparation. You may be in trouble if you don’t have a recent backup and have fallen victim to B0r0nt0k ransomware

Applying the latest security patches to your applications and servers is potentially the single most important step you can take to shore up your defenses, but it is not enough. Combating ransomware requires a multilayer defensive approach, including intrusion prevention services to block application exploits, and advanced malware-detection tools that use machine learning and behavioral detection to identify evasive payloads

What Else to Do

The most active way to prevent B0r0nt0K from entering your Linux server is to close the SSH (secure shell) and the FTP (file transfer protocol) ports,

  • Restore the site from source control or backups;
  • Change all admin passwords;
  • Audit the software stack for known vulnerabilities that could have allowed the attacker in, and patch as appropriate;
  • Audit the site’s configuration for any weak spots;
  • Disable services that are not critical, and close those open ports;
  • Ensure backups are operational; and
  • Conduct a penetration test of the Internet-facing network footprint.
