How to remove BQTLOCK Ransomware and Decrypt .BQTLOCK Files?
Advanced Decryptor for BQTLOCK
BQTLOCK ransomware has quickly emerged as a disruptive cyber threat, encrypting files with the “.BQTLOCK” extension and leaving victims locked out of their systems. Our security team has analyzed its encryption techniques and engineered a professional decryptor capable of restoring encrypted files across Windows, Linux, and VMware environments. Unlike random online tools, our decryptor is built on real-world research of BQTLOCK’s hybrid encryption and is designed for stability and precision.

How the Recovery Mechanism Works?
The recovery process blends cryptographic analysis with automated workflows to ensure safe decryption.
- Unique ID Matching: Each ransom note (e.g., READ_ME-NOW_2526968.txt) contains a victim ID, which is mapped to a specific encryption batch.
- Hybrid Key Handling: BQTLOCK uses AES-256 for file encryption and RSA-4096 to secure keys. Our tool replicates this structure and leverages ID-based mapping to retrieve decryption pathways.
- Cloud-Synced Verification: A secure sandbox validates integrity before actual restoration begins, preventing further file damage.
- Universal Support Option: Even in cases where ransom notes are missing, our premium decryptor can handle the most recent variants of BQTLOCK.

What You Need for the Process?
To maximize the success rate, victims must prepare the following:
- A copy of the ransom note (READ_ME-NOW_*.txt).
- Samples of encrypted files with the “.BQTLOCK” extension.
- Stable internet connection for encrypted session handling.
- Administrator access to run the decryption utilities properly.
First Response After a BQTLOCK Attack
When dealing with ransomware, time and decisions matter.
- Isolate Immediately: Disconnect the infected system from the network to stop further encryption.
- Preserve Evidence: Do not delete ransom notes, logs, or encrypted files. These are crucial for recovery and forensic validation.
- Avoid Rebooting: Restarting infected systems could trigger additional encryption scripts.
- Seek Professional Help: DIY recovery attempts or unverified tools often cause permanent data loss.
Steps to Recover .BQTLOCK Encrypted Files
BQTLOCK spreads aggressively across networks, encrypting documents, images, databases, and backups. Our decryptor provides a controlled and verifiable recovery path. Victims should submit encrypted samples along with the ransom note for an initial evaluation. Once confirmed, the tool runs decryption with real-time monitoring to restore files safely.
Free Recovery Alternatives
Some recovery methods do not involve payment but come with restrictions.
Backup Restoration: Victims with offline or immutable backups can restore systems by wiping infected devices and reloading clean copies. This remains the safest free solution if backups are intact.
VM Snapshots: For virtualized systems, rolling back to earlier snapshots may recover functionality. However, BQTLOCK is known to delete shadow copies, so availability must be verified before attempting this method.
Paid Recovery Options
When free options are not viable, enterprises often explore paid methods.
Negotiation with Attackers: Victims are instructed to contact threat actors through Telegram or Twitter (@ZeroDayX1). Payments are demanded in Monero (XMR), ranging from 13 XMR to over 500 XMR, depending on the victim’s ID wave. However, paying offers no guarantee of full recovery, and often results in secondary attacks.
Third-Party Negotiators: Some companies use intermediaries to reduce ransom demands or verify attacker decryptors. While sometimes successful, these services are costly and carry legal and ethical concerns.
Our Custom Decryptor: We offer a dedicated BQTLOCK decryptor, reverse-engineered to exploit weaknesses in its encryption logic. Our tool requires victim IDs and encrypted samples but provides a safer, more transparent recovery path than ransom payments.
Step-by-Step BQTLOCK Recovery Guide with Our Decryptor
Assess the Infection
Check the encrypted files for the “.BQTLOCK” extension and confirm the presence of the ransom note (READ_ME-NOW_.txt*).
Secure the Environment
Disconnect compromised systems from your network to make sure encryption scripts cannot spread further.
Engage Our Recovery Team
Send us sample encrypted files along with the ransom note. Our specialists will confirm the variant and prepare the recovery plan.
Run Our Decryptor
Launch the BQTLOCK Decryptor tool with administrator privileges. The tool requires an internet connection to securely communicate with our servers.
Enter Your Victim ID
Use the ID provided in the ransom note to match your files with the correct encryption batch.
Start the Decryptor
Begin the process. The tool will restore your files to their original, usable state while maintaining integrity checks throughout.
Offline vs. Online Options
- Offline Mode: Designed for air-gapped systems. Decryption is handled via external drive transfer and a clean boot environment.
- Online Mode: Provides faster turnaround with live monitoring and expert support. Files are decrypted through a secure encrypted channel.
Our decryptor supports both modes, ensuring recovery flexibility for enterprises, governments, and industrial systems.

Technical Profile of BQTLOCK
BQTLOCK is a crypto-ransomware strain first observed in July 2025, operated as Ransomware-as-a-Service (RaaS). Originating from Lebanon, it is linked to threat actor Karim Fayad (ZeroDayX). The ransomware encrypts data using a hybrid model (AES-256 + RSA-4096) and appends the “.BQTLOCK” extension to locked files.
Attack Vectors and Distribution
BQTLOCK primarily spreads through phishing campaigns, malicious attachments, pirated software, exploit kits, and deceptive advertisements. Once executed, it establishes persistence and rapidly encrypts local files and network-shared drives. Known infection methods also include fake software cracks, torrent files, and drive-by downloads.
Attacker Tools and TTPs
Analysis reveals that BQTLOCK operators follow well-documented intrusion patterns:
- Initial Access: Delivered via infected emails, malicious Office macros, or cracked software.
- Reconnaissance: Attackers map networks to identify valuable systems before triggering encryption.
- Credential Theft: Password-stealing trojans are sometimes bundled to harvest credentials for deeper infiltration.
- Defense Evasion: The malware disables recovery mechanisms such as shadow copies and system restore points.
- Exfiltration & Extortion: While primary focus remains encryption, some victims report stolen data threats, aligning with double extortion trends.
Tools often associated with BQTLOCK include remote access software, network scanners, and customized encryption executables.
Indicators of Compromise (IOCs)
Victims can identify BQTLOCK infections through the following IOCs:
- File Extensions: Documents renamed to “filename.extension.BQTLOCK”.
- Ransom Note: READ_ME-NOW_<7-8 digits>.txt dropped in affected directories.
- Malware File: “bqt_icon.ico” appears as part of the payload.
- Wallets: Monero (XMR) wallets linked to operators (e.g., 89RQN2EUmiX6vL7nTv3viqUAgbDpN4ab…).
- Samples: SHA-256 hash 324eabc27a25f524c94bb62573986b3335ab5181ddc6825d959d16aaaccdc7aa confirmed in VirusTotal.
BQTLOCK Ransom Note (READ_ME-NOW_2526968.txt) Overview
The ransom note contains the following message:
ALL YOUR FILES HAVE BEEN ENCRYPTED BY BQTLOCK!
Your entire network has been penetrated, and all data is now encrypted using military-grade AES-256 and RSA-4096 algorithms. Decryption is impossible without our unique private key.
Do NOT attempt to recover your files using third-party tools or backups. Any such action will result in the irreversible loss of your data.
