Btix Ransomware – a ransom-demanding threat that is a sibling of Dharma virus

Btix ransomware virus
Btix ransomware is a file-locking virus that belongs to the Dharma and Crysis malware families

Btix Ransomware is a dangerous form of malware that appears to belongs to the Dharma and CrySiS ransomware family. The threat was first spotted by a cybersecurity researcher named Jakub Kroustek.[1] The computer specialist discovered that the file-locking infection brings a malicious executable named payload.exe to the targeted system and takes 92.5 KB of space. Btix virus uses unique encryption algorithms to forcefully lock all files that are located on the infected machine. Once this happens, files end up with the .btix appendix. For example, your table.docx document is modified to table.docx.btix and you are no longer able to access this file unless you get a decryption tool. As a solution, cybercriminals offer to buy a decryption tool from them. Such thing is claimed by displaying a ransom message in the “FILES ENCRYPTED.txt” text file. The victims are urged to obtain Bitcoins via the LocalBitcoins[2] website and contact the criminals by sending a message to encrypt11@cock.li email address.

Btix Ransomware has the same operating principle as other Dharma family members. SHA-256[3] algorithm is the secret code that is used to lock files on the targeted machine and leave them with .btix extensions. After encryption, both encryption and decryption tools are stored on remote servers and kept out of reach for anyone except the owners themselves.

Ransomware threats are one of the most dangerous cyber beasts that have been lurking out in the cyberspace for years. Btix Ransomware and similar viruses are capable of stealthily entering the targeted computer system and modifying various components and processes in it. The malware can place suspicious entries in the Windows Registry and force malware-laden processes to run via the Task Manager section.

The ransom price includes no particular details in the “FILES ENCRYPTED.txt” message, however, crooks are likely to urge for prices between $500 and $100. Of course, this amount usually needs to be paid in Bitcoin, Ethereum, or other popular cryptocurrencies as such processes ensure safety and anonymity. Take a look at the entire ransom note:

Btix ransomware is a damaging cyber threat that might bring other unwanted consequences to the user's computer system. Some ransomware viruses are capable not only to lock up files but this malware might also:

  • Delete Shadow Volume Copies of your files.
  • Manipulate your system's files and components.
  • Avoid the detection of some types of antivirus tools.
  • Inject other malware, e.g. trojans.
  • Relate in data theft.

We guess that we have already provided enough reasons for you to run and complete the Btix ransomware removal right away. Note that, some computer security tools such as AVG or Avast detect this ransomware as Win32:Malware-gen. However, other possible names are Trojan.Ransom.Crysis.E, Ransom.Crysis.Generic, Ransom.Crysis, W32.Ransom.Gen, GenericRXEA-WW!A1CFDDC7308E, Ransom:Win32/Wadhrama.C, etc.[4]

Also, before you remove Btix ransomware, you can try to scan your computer system with a tool such as Reimage and detect all malicious components. The elimination needs to be performed in all infected areas of the machine, otherwise, the ransomware might renew itself automatically within the upcoming computer reboot.

You might notice that the cybercriminals are trying to scare you in different ways and to prove that files can be recovered only with their help. They are claiming in the note that data which has been locked by Btix virus cannot be restored or modified with the help of other tools or it will be permanently lost. However, this is only a trick to force you to pay the crooks. After you get rid of the threat, you can definitely give a try to the tools that we have provided at the end of this page.

File-locking malware appears after opening suspicious email attachments

Ransom-demanding and file-locking viruses are a common occurrence which distributes via suspicious email messages and infectious executables that come attached to the emails. According to security experts,[5] the ransomware-related payload is usually provided in a specific attached file or inserted in an infected hyperlink that is given in the email letter.

We strongly recommend identifying each email message before opening it. If you were not expecting to receive something important recently, better delete all rogue emails that fall in your inbox and spam sections.[6] Another good idea is to scan files by using antivirus tools as these programs will notify you if something malicious is hiding behind them.

Continuously, ransomware payload can be found in peer-to-peer networks and indirect downloading links. This type of malware is popularly distributed in third-party websites such as Torrents or The Pirate Bay.

Btix ransomware removal guidance on Windows devices and file restoring

If you are looking for ways to remove Btix ransomware on your own, do not waste your time as this process needs to be performed only with reputable anti-malware tools. Additionally, your system requires a full scan for malware which can be easily carried out with specific programs such as Reimage, SpyHunterCombo Cleaner, or Malwarebytes Malwarebytes.

Btix ransomware removal is a responsible process to perform as the human eye might not spot all suspicious content and accidentally leave some malware-laden objects lurking in the machine system. If this happens, the ransomware might easily renew itself and its malicious activities the next time when you start your computer.

However, after you get rid o Btix virus, make sure to take precautionary measures that are needed to keep important files safe from similar infections in the future. Our experts recommend storing copies of valuable information on portable devices such as USB Flash Drives or keeping them on remote servers such as iCloud.
