BeFirst Ransomware Decryptor
BeFirst ransomware is a recently emerged variant from the well-known MedusaLocker family. This strain has gained notoriety for its sophisticated encryption routines and dual-extortion tactics that target both corporate networks and individual systems.
Our cybersecurity engineers have successfully reverse-engineered BeFirst samples and designed a dedicated BeFirst Decryptor, purpose-built to restore encrypted data across Windows-based infrastructures.
Developed through months of algorithmic and cryptographic research, this decryptor integrates AI-driven file mapping and blockchain verification systems to safely restore files without altering their structure or metadata. It offers exceptional accuracy, reliability, and compatibility for both on-premise and hybrid environments.
How the BeFirst Decryptor Operates
AI & Blockchain Verification: Every encrypted file is securely processed within a cloud environment where blockchain validation ensures the authenticity and safety of the decryption process.
Victim ID Correlation: Each ransom note contains a personal identifier that our system uses to align your data with the corresponding encryption keys.
Universal Recovery Module: If the ransom note has been deleted or lost, our advanced universal algorithm can analyze file headers to identify and process multiple BeFirst variants.
Read-Only File Analysis: Before initiating recovery, the tool performs a non-destructive scan to evaluate the integrity of encrypted files and confirm their suitability for restoration.
Immediate Actions Following a BeFirst Infection
BeFirst ransomware acts quickly once executed — encrypting accessible data and adding the “.befirst1” extension to affected files. Your response in the first few moments determines the success of your recovery.
Disconnect Infected Systems
Immediately sever all affected devices from your network. This halts the ransomware’s ability to spread to shared resources, servers, or connected storage drives.
Preserve Digital Evidence
Do not delete any ransom note files (“READ_NOTE.html”) or encrypted data. Preserve event logs, temporary files, and memory captures — they are crucial for forensic investigation and variant identification.
Avoid System Reboots and File Alterations
Restarting the system or modifying encrypted files can activate hidden encryption scripts or destroy temporary decryption keys held in memory. Leave all affected data untouched until professional analysis is complete.
Contact Certified Recovery Experts
Avoid using random decryptors or online “quick fix” tools, as many are malicious or incorrectly configured. Instead, consult verified cybersecurity recovery teams who can conduct a structured evaluation and ensure safe file restoration.
Free BeFirst Ransomware Recovery Methods
Restore from Backups
If you maintain clean, offline backups, this remains the safest recovery route. Confirm the integrity of each backup using checksum or hash validation before reintroducing files to avoid reinfection or incomplete recovery.
Recover Using Shadow Copies
Although BeFirst often deletes Windows shadow copies, certain configurations may retain residual restore points. Software such as ShadowExplorer can sometimes access these hidden recovery snapshots if the deletion process was incomplete.
Paid BeFirst Ransomware Recovery Options
Negotiation with Threat Actors (Discouraged)
Some victims attempt to engage directly with the attackers to purchase a decryptor. This approach, however, carries serious risks — cybercriminals frequently fail to provide functional tools even after payment, and in some cases, re-extort victims. Additionally, ransom payments may contravene regional laws and further finance illicit activity.
Third-Party Negotiators and Incident Response Teams
Independent negotiators or forensic specialists may act as secure intermediaries between victims and attackers. They are capable of validating proof of decryption, verifying authenticity, and sometimes lowering ransom demands. However, these services often come with high retainers or success-based fees.
The Advanced BeFirst Decryptor
Our proprietary BeFirst Decryptor is a secure and legitimate solution that avoids paying the ransom entirely. Built through extensive research into MedusaLocker’s encryption methodology, it utilizes a combination of login ID recognition and AI-based blockchain analytics to restore data safely.
The recovery is performed within sandboxed cloud environments, ensuring transparency, traceability, and absolute safety from reinfection. Once you provide a few encrypted samples and the ransom note, our experts deliver a tailored recovery roadmap and estimated restoration timeline.
Detailed BeFirst Recovery Workflow with Our Decryptor
Evaluate the Infection
Begin by identifying all affected files. BeFirst encrypts and renames data using extensions such as .befirst1, .befirst2, or other numeric variations. Confirm that the “READ_NOTE.html” ransom note is present — this document contains your unique Victim ID, required for accurate key mapping.
Secure and Stabilize the Network
Isolate compromised endpoints and servers immediately. Disconnect from shared drives and network storage, ensuring that any automated synchronization processes are suspended. Verify that no residual encryption scripts are running before proceeding.
Submit Samples for Verification
Send several encrypted files and the ransom note to our response team for inspection. This allows us to identify the precise BeFirst variant and encryption structure, after which we can provide an analysis and recovery estimate tailored to your environment.
Deploy the BeFirst Decryptor
Once validation is complete, download the decryptor and run it as an administrator to enable full system access. A stable network connection is required, as the tool communicates securely with our blockchain-backed servers for decryption key verification.
Victim ID Input:
Extract the Victim ID from your ransom note and enter it when prompted. This allows our system to accurately match your encrypted files to the correct encryption pattern.
Initiate Decryption:
After configuration, start the process. The BeFirst Decryptor will restore your data to its original condition while preserving file integrity, timestamps, and structure.
Offline and Online Decryption Modes
Offline Recovery Mode:
Best suited for high-security or air-gapped systems, this method allows decryption without internet access. Encrypted files can be safely transferred via an external drive to a clean recovery workstation.
Online Recovery Mode:
For rapid and monitored restoration, this option connects directly to our secure blockchain servers. It offers continuous progress tracking, integrity checks, and access to live support.
Our decryptor supports both methods, delivering flexible and efficient solutions for enterprises, government networks, and industrial systems alike.
BeFirst Ransomware: Technical Behavior and Overview
BeFirst ransomware employs a hybrid encryption algorithm utilizing AES for file encryption and RSA for key protection. Once the payload executes, it encrypts all accessible user files, appending the extension “.befirst1” (or a numeric variant).
It then modifies the desktop wallpaper and leaves behind a ransom note titled “READ_NOTE.html.” Victims are instructed to reach out to the attackers via Tor or encrypted email channels within 72 hours, after which ransom amounts are raised. If ignored, the criminals threaten to leak or sell the exfiltrated data.
Examination of the Ransom Note
The message left by BeFirst mirrors the tone and layout of traditional MedusaLocker notes. It claims the network has been compromised, warns users against tampering with encrypted data, and offers to decrypt two or three files as proof of authenticity.
Excerpt from BeFirst Ransom Note:
Your personal ID:
–
YOUR COMPANY NETWORK HAS BEEN PENETRATED

Encryption and Behavioral Analysis
BeFirst encrypts a wide variety of file formats — from personal documents to business-critical databases. It intentionally excludes operating system directories to maintain boot functionality while ensuring maximum data disruption.
The malware deletes Windows shadow copies to prevent quick recovery, then sets up registry entries for persistence. Each file’s header is altered, making standard recovery tools ineffective.
Infection Vectors and Distribution Methods
BeFirst’s infection pathways are consistent with most ransomware campaigns. Common entry methods include:
- Malicious email attachments (e.g., disguised invoices or HR documents).
- Archive files (ZIP, RAR) containing executable payloads.
- Drive-by downloads from compromised or fraudulent websites.
- Exploitation of unsecured RDP (Remote Desktop Protocol) connections.
- Fake software updates, pirated content, or illegal activation tools.
After infiltration, BeFirst contacts its command-and-control (C2) infrastructure to exchange encryption keys and begin the encryption cycle.
Tactics, Techniques, and Procedures (TTPs)
BeFirst’s operational methods align closely with MITRE ATT&CK tactics:
| MITRE Tactic | Technique ID | Purpose |
| Initial Access | T1566.001 | Phishing with malicious attachments |
| Execution | T1204 | Launching user-initiated payloads |
| Persistence | T1547 | Registry modification for startup persistence |
| Defense Evasion | T1562 | Disabling security tools and deleting backups |
| Credential Access | T1003 | Stealing stored credentials via memory scraping |
| Exfiltration | T1048 | Transferring data over encrypted channels |
| Impact | T1486 | File encryption through AES + RSA |
Tools and Utilities Employed by BeFirst Operators
