Our security team has engineered a decryptor specifically for Proton/Shinra ransomware. This tool was built after reverse-engineering the encryption routines used in variants like .OkoR991eGf.OhpWdBwm. It has been tested on Windows servers, VMware ESXi, and business environments, delivering consistent results for recovering files without corruption.
The decryptor combines intelligence-driven mapping and secure execution. It uses the unique identifier found inside ransom notes to align decryption keys with encrypted files. For victims without a ransom note, we offer a premium universal option that relies on advanced key simulation models. Before running, the decryptor performs a read-only scan to ensure files are recoverable without introducing new risks.
To ensure successful decryption, the following are needed:
Access to the ransom note (usually HELPME.txt or Recovery.txt)
Encrypted files with the .OkoR991eGf.OhpWdBwm extension
Administrative privileges on the system
A stable internet connection for secure key mapping
Immediate Steps After a Proton/Shinra Attack
If your infrastructure has been compromised, speed and precision are crucial. Disconnect all affected systems immediately to stop ransomware spread. Do not delete ransom notes or modify encrypted files. Shutting down compromised systems without rebooting them helps preserve volatile evidence. Finally, contact professional recovery experts before attempting any manual fixes that could damage files further.
Free Recovery Options for Victims
Some options exist for limited recovery without paying ransom:
Backup Restoration
If offline or off-site backups are available, wiping infected machines and restoring clean images is the safest option. Backup integrity should be verified to ensure data was not partially encrypted.
Snapshot Reversions
For environments running VMware or similar hypervisors, pre-infection snapshots can be used to roll back systems to a safe state. However, verify logs to ensure ransomware did not delete these snapshots.
Paid Recovery Paths
If free methods fail, paid methods may be considered.
Paying the Attackers
Victims may be tempted to pay the ransom, but risks include non-functional decryptors, hidden backdoors, or refusal by attackers to deliver keys. This also raises legal and ethical issues depending on jurisdiction.
Third-Party Negotiation
Professional negotiators can reduce ransom amounts and validate whether attackers actually provide working decryptors. However, this service is costly and time-consuming.
Our Enterprise Decryptor
Our decryptor is designed to handle variants like .OkoR991eGf.OhpWdBwm safely. It uses ID-based mapping to align with unique encryption batches and supports both online and offline decryption modes. This ensures recovery even if no ransom note is available. Unlike attacker-provided tools, our solution operates in a secure, sandboxed environment with blockchain verification of recovery integrity.

Proton/Shinra is a notorious family of ransomware operating in Ransomware-as-a-Service (RaaS) mode. The .OkoR991eGf.OhpWdBwm variant represents a V3 style of Shinra where file extensions are randomized strings, making identification difficult. It typically drops ransom notes under names such as HELPME.txt or Recovery.txt and instructs victims to email the operators with a unique ID.
Behavior and Impact of This Variant
This ransomware encrypts critical business data using hybrid cryptographic methods, making files unreadable. It deletes Windows shadow copies to block recovery and clears event logs with wevtutil to cover its tracks. Victims often find their desktop wallpaper replaced with a ransom message while legal notices are added to Windows registry policies.
Tools and Techniques Observed in Attacks
Shinra is aggressive in disabling business operations. It terminates processes linked to SQL databases, QuickBooks, VMware, and productivity apps. Security solutions are also targeted, with AV and EDR processes forcibly killed. This ensures uninterrupted encryption. Known forensic traces include registry edits, file placement in startup folders, and attempts to overwrite wallpapers and notices.
Sample ID Ransomware SHA-1: b0a3bdc32c006b4d2986115971b07d7be137fb1d
Registry changes: wallpaper path in HKCU\Control Panel\Desktop, and legal notice text in HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System
Proton/Shinra’s tactics align with enterprise-targeted ransomware operations. It gains initial access through compromised credentials, phishing, or exploiting vulnerabilities. Once inside, it establishes persistence by copying executables into startup folders. It evades defenses by disabling AV tools and erasing event logs. For impact, it encrypts user data, deletes backups, and presents ransom notes. Exfiltration of data before encryption has also been reported, making it a double-extortion threat.
Ransom Note Breakdown
The ransom note file contains the following message:
Your files have been encrypted
To recover them, please contact us via email:
Write the ID in the email subject : 4EAD8DB0E976F0D8187DD8707633D99B
Email 1: data.recovery@onionmail.org
Email 2: revival.recovery@2mail.co
To ensure decryption you can send 1-2 files (less than 1MB) we will decrypt it for free
Data and Victim Analysis
Proton/Shinra has been observed worldwide, particularly in industries such as finance, healthcare, education, and managed service providers. Many victims report disruption of SQL databases and virtualized infrastructures.

What is Proton/Shinra Ransomware and Why It Matters?
This ransomware is not just about file encryption; it’s about halting entire infrastructures. With randomized extensions like .OkoR991eGf.OhpWdBwm, strong hybrid encryption, and data exfiltration practices, Shinra represents a major threat to enterprises. Unlike older ransomware that hit isolated machines, Proton/Shinra is designed for network-wide disruption.
Conclusion: Path to Safe Data Restoration
Proton/Shinra ransomware poses a serious risk with its advanced features, but recovery is still possible. Victims should prioritize safe containment, preserve all forensic evidence, and explore both free recovery methods like backups and professional decryptors. Our decryptor has already restored files for multiple organizations hit by Proton/Shinra. Whether through offline or cloud-assisted modes, recovery without ransom payment is achievable.
Frequently Asked Questions
Currently, no. Free decryptors exist for older ransomware, but Proton/Shinra has no public solution yet.
Yes, unless using our universal decryptor, which can recover data without it.
Not recommended. Even if you pay, there’s no guarantee of working keys, and legal risks apply.
