How to Restore .bitrix Encrypted Files from Bitrix Ransomware Attack?
Our Specialized Bitrix Recovery Solution
Our cybersecurity research team has conducted an in-depth analysis of Bitrix ransomware and developed a custom-built recovery tool. This decryptor is engineered to address the .bitrix file encryption, operating in secure environments to reduce the risk of file corruption. Designed primarily for Windows systems, it has been tested in controlled lab conditions against multiple Bitrix samples.

How the Recovery Process Works?
Our system uses cryptographic pattern analysis, ransom note parsing, and controlled sandbox environments to attempt safe decryption. It maps the unique victim ID from the ransom note to the corresponding encryption batch and verifies file health before making any modifications. When the ransom note is missing, our enhanced mode can attempt partial restoration using encrypted file headers and known variant characteristics.

Requirements Before Starting Recovery
To use the Bitrix recovery tool effectively, you will need:
- The ransom note generated by Bitrix ransomware.
- Access to encrypted files.
- A stable internet connection for secure online processing.
- Administrator privileges on the affected system.
Immediate Response After a Bitrix Attack
Time is critical once you detect a Bitrix infection.
- Disconnect the infected system from the internet and local network to prevent the spread.
- Preserve the ransom note and do not modify encrypted files.
- Avoid rebooting unless directed by a professional.
- Contact a trusted recovery specialist as soon as possible.
Understanding the Bitrix Ransomware Threat
Bitrix is a file-encrypting ransomware that appends the .bitrix extension to targeted files. Victims receive a pop-up ransom note warning them not to attempt manual decryption, claiming that doing so will make recovery impossible. Without the decryption key held by the attackers, restoring files is extremely difficult. Paying the ransom is discouraged due to the high risk of non-delivery of working decryptors.
Decryption Options for Bitrix Ransomware (.bitrix)
When your files are locked by Bitrix ransomware, you essentially have two main avenues to explore: attempting a no-cost recovery or paying the attackers. Each path comes with its own risks, limitations, and potential outcomes. It’s critical to understand them fully before deciding on a course of action.
1. Paid Approach: Ransom Payment
Bitrix’s ransom note directs victims to contact the attackers at Bitrixdec@proton.me for instructions. Typically, they request payment in cryptocurrency (most often Bitcoin) in exchange for a decryption utility and a unique key.
Key considerations before paying:
- There is no guarantee that paying will restore your files. Cybercriminals frequently fail to deliver decryption tools even after receiving payment.
- Payment fuels criminal enterprises, funding more ransomware campaigns and further attacks.
- Decryption tools provided by criminals can sometimes contain backdoors or additional malware.
How payment generally works?
- Victim contacts attacker using the provided email address.
- Attacker responds with the ransom amount and cryptocurrency wallet address.
- Payment is made in Bitcoin or another specified cryptocurrency.
- Attacker may send a decryptor along with instructions for use — or may disappear entirely.
2. Free Methods: Possible Recovery without Paying
Currently, there is no publicly available decryptor for Bitrix ransomware. However, there are legitimate steps victims can try that may allow partial or complete recovery without paying the ransom.
Potential recovery methods:
- Backup restoration: If you have copies of your data stored on external drives, network-attached storage, or cloud backups created before infection, you can restore files after removing the malware.
- Shadow Volume Copies: Some ransomware variants fail to delete Windows’ built-in restore points. Using tools like ShadowExplorer, you may be able to recover earlier versions of files.
- Data recovery software: Programs like Recuva, PhotoRec, or R-Studio can sometimes recover deleted or overwritten files, though success rates vary.
- Public decryptors: Security researchers occasionally release free decryption tools for ransomware families with weak encryption. Checking reputable sources like No More Ransom Project is recommended.
- File carving from system snapshots: Advanced recovery labs can attempt deep forensic recovery from disk sectors, though this is time-intensive and may not be fully successful.

Known Indicators of Compromise (IOCs)
- File Extension: .bitrix
- Ransom Note: Pop-up referencing Bitrix@proton.me
- Registry Changes: Modified Run keys for persistence.
- Dropped Files: Executables in %AppData% or %Temp% directories.
- Detection Names:
- Avast: MalwareX-gen [Ransom]

TTPs of Bitrix Operators
Initial Access – Phishing attachments, malicious downloads, pirated software installers, drive-by attacks.
Execution – Launches ransomware payload, encrypts target file types, injects into legitimate processes.
Persistence – Registry autorun entries, dropped executables in system folders.
Defense Evasion – Terminates security software, deletes shadow copies (vssadmin delete shadows /all /quiet).
Data Encryption – Likely hybrid cryptography (AES + RSA), renames files with .bitrix extension.
Tools Associated with Bitrix Campaigns
- Compression Tools: WinRAR, 7-Zip for packaging stolen data.
- Remote Access Software: AnyDesk, TeamViewer.
- Credential Theft: Possible Mimikatz usage.
- File Transfer: RClone, FTP clients.
- Persistence Scripts: PowerShell autorun scripts.
Infection Methods
Bitrix typically spreads through infected email attachments, malicious ads, pirated software, and trojanized installers. In some cases, it can propagate via removable media or shared network drives. Simply opening a malicious file may be enough to trigger the attack.

The Ransom Note Breakdown
The Bitrix ransom note is delivered via a pop-up and contains the following message:
All your files have been encrypted!
Your personal ID KEY :
–Copy to clipboard
For decryption contact Email: Bitrix@proton.me
DO not try to decrypt it yourself, otherwise recovery will be impossible !!!
Prevention Strategies
Protecting against Bitrix involves a layered security approach:
- Regular backups stored offline and in multiple locations.
- Multi-factor authentication on all accounts.
- Cautious handling of email attachments and links.
- Regular updates for operating systems and applications.
- Strong endpoint protection and regular security audits.
Conclusion
Bitrix ransomware can cause severe data loss and operational downtime. With the right expertise and tools, recovery is possible without paying the ransom.
