Bitx ransomware

Bitx ransomware is the persistent threat that launches various processes in the Windows system to keep on running

Bitx ransomwareBitx ransomware is the file-locking virus that also tends to damage system files and creates huge frustration for users when the performance is significantly diminished due to additional background processes. This is the version of Dharma ransomware that was released late November 2019, three years after the first discovery. The recent version is still focusing on making users’ files inaccessible and marking them with an identification number and .bitx appendix, so the payment can be demanded, for the alleged data recovery. Unfortunately, paying the ransom is rarely getting those files back because criminals don’t care for your belongings. Although the primary process of such a virus attack is file locking, ransomware is launching other processes in the background and disabling system features, functions, or even deleting some files to ensure that data recovery and virus termination is barely possible.

Bitx ransomware virus can manage to disable security functions and delete Shadow Volume Copies, so you need to pay for criminals to get files restored. However, an encouraging message that gets delivered to you via FILES ENCRYPTED.txt should be ignored and malware deleted from the machine. Anything leading after the contact held between you and hackers can lead to lost money, data, and corrupted machine or even direct blackmail when threat actors manage to obtain your personal details.

Name Bitx ransomware
Family Dharma/Crysis ransomware
Contact emails [email protected] and [email protected]
Symptoms The threat infects various machines and starts encrypting common types of files found on the machine. All locked files become useless and marked using a unique extension. Additional processes get launched in the background, so the persistence of the threat goes up and it is more difficult to eliminate the cryptovirus. The ransom note appears on the computer with the statement that only paying demanded ransom can recover the data back
File appendix All encoded files get marked using a file marker with the .id.[[email protected]].bitx pattern that includes victims’ ID 
Distribution Infected email attachments and other malware get used to spreading ransomware infections around. File attachments include malicious macros,[1] and often such data gets pre-packed in pirated software packages[2]. The encryption process gets initiated immediately after the infiltration
Ransom note Virus creators deliver the ransom-demanding note, contact information, other details in the text file FILES ENCRYPTED.txt and payment instruction in the pop-up program window that mainly is named Info.hta
Elimination You need to remove Bitx ransomware using the anti-malware program that can clean the whole machine for you, so data recovery is not leading up to permanently lost files
System file repair When the system is ransomware-free, you should focus on improving the performance and tackling virus damage, so files restored using your backups cannot get affected again. Try system repair tools like Reimage Reimage Cleaner that may find and fix affected, corrupted or damaged system data in the registry and other places

Bitx ransomware is the threat that belongs to the cryptovirus category due to the focus on cryptocurrency-extortion. Criminals behind the threat demand victims to pay because data can either be decrypted using the alleged decryption tool or replaced with safe copies from backups, using third-party file recovery software. However, criminals shouldn’t be trusted, especially when malware has been encrypting files and demanding payments for years.

Bitx ransomware is almost identical to other versions in the family of Dharma like KARLS, NWA, Korea, Stun, so the technique to use a particular pattern for file markers, the ransom message file, the payment instructions pop-up, file names, and the note itself are the same. But since each version comes out separately the contact information differs from variant to variant.

The ransom message that Bitx ransomware developers deliver you is short and provides the contact information for malware creators. A program window that appears on the screen directly includes scary claims and payment instructions to make you more eager to pay up. You should ignore both of those files.

FILES ENCRYPTED.txt reads the following:

all your data has been locked us
You want to return?
write email [email protected] or [email protected]

Besides the encryption, Bitx files virus can erase files from the Windows Registry, add new entries there, in other directories, folders on the system. This threat is one of the most dangerous because secondary payloads might be added to your machine without you noticing and run such processes like data-stealing or cryptocurrency mining that uses resources of the computer directly. The more you wait before deleting the virus, the more damaged your machine gets, so react as soon as you receive the ransom message.  Bitx ransomware virus
Bitx ransomware is the blaickmail-based threat that focuses on getting money from victims.
Bitx ransomware was discovered and reported by malware researcher Jakub Kroustek that revealed tons of them throughout the years. He also placed a found sample on the VirusTotal platform[3] that revealed a detection rate for this notorious threat with the following names:

  • TR/Dropper.Gen;
  • Trojan.Ransom.Crysis.E;
  • Win.Trojan.Dharma-6668198-0;
  • Trojan.Ransom.Crysis.E;
  • Ransom-Dharma!502B53C1602B;
  • Trojan.Win32.Ransom.94720.F;
  • Ransom.Crysis.

These names vary for each AV tool because those detection engines base their services on different virus databases. You should note that this virus can be detected with various names and results that show up on the screen for you. Nevertheless, the initial detection rate and results can indicate which anti-malware engine you can choose for the proper Bitx ransomware removal. 

We should note that anti-malware tools are not capable of recovering encoded files or fixing virus damage during the system scan and virus elimination processes. Such software is designed to get rid of the malicious files and core data of the infection. You need additional help in repairing the damage and recovering your files. Unfortunately, Bitx ransomware is not decryptable at the time of writing this guide, so options for file recovery are not that great. 

The best tip from experts[4] is to remove Bitx ransomware using trustworthy anti-malware application and then rely on your file backups stored on cloud services or external devices to replace encoded data with safe copies. Also, third-party data restoring software can help or services that some researchers use. However, don’t trust people online that offer to decrypt your files for a fee because, in most cases, those scammers contact virus developers and try to get your files decrypted by paying the ransom.

You better get rid of the malicious crypto-extortion based virus and lean the system using a PC optimizer. Software like Reimage Reimage Cleaner can possibly check the system for damaged, corrupted, or affected files in the registry, system folders and help you fight Bitx ransomware virus damage this way. If you try to interfere with Windows Registry or other directories, you can get your machine corrupted permanently and lose data completely. Bitx virus
Bitx ransomware is the threat that tends to be persistent and affecting more than encrypted files, so you should get professional AV tools for the proper termination.

The malicious script gets triggered once you open the infectious file

Ransomware is the infection that mainly spreads around with the use of other malware or infected files, dropping the payload directly on the machine. Payload droppers get on the system in the background, and the victim notices the infection when ransomware script is launched, and encryption starts.

Such malicious files can get delivered via social media, fake websites, spam email campaigns, file-sharing services, pirated software distributors, and other methods involving silent file distribution. When the executable is installed it launches the payload immediately. Malicious documents have macro viruses that need to get triggered by enabling additional content. It is done by the user unknowingly, in most cases.

You can avoid this serious malware infiltration if you pay closer attention to the content you visit, pages you surf online, and spam emails you get on a daily basis. Make sure to look for red flags like suspicious senders or names of the company you never use or heard of. Delete any email that is not expected, especially when files or links get attached to the notification.
