Delocker Ransomware Decryptor
Delocker ransomware, belonging to the MedusaLocker family, has become a highly malicious threat, infiltrating systems to encrypt crucial files and demanding ransom for decryption keys. This comprehensive guide examines Delocker’s infection methods, its impacts on both VM and Windows environments, and recovery strategies—highlighting a specialized Decryptor tool as a core solution.
Delocker Decryptor Tool Overview
The Delocker Decryptor Tool is a specialized solution designed to rescue files encrypted by Delocker—no ransom required. Harnessing advanced cryptographic techniques and secure server-side processing, it restores access to encrypted data efficiently.
Highlights:
- NAS Compatibility: Supports QNAP and other NAS devices, provided encrypted volumes remain accessible.
- Algorithm-Specific: Tailored to handle .delocker1, .delocker5, .delocker10, .delocker20, and related file extensions.
- Safe & User-Friendly: No data deletion or corruption; accessible to non-technical users.
- Refund Assurance: Offers a money-back guarantee if decryption fails.
Delocker Attack on VMware ESXi
Delocker has a dangerous variant targeting VMware ESXi hypervisors—environments critical to many enterprises.
Modus Operandi:
- ESXi Exploitation: Attackers exploit known vulnerabilities like CVE-2021-21974 in OpenSLP to gain system access.
- Powerful Encryption: A hybrid use of RSA and AES renders entire VMs inaccessible.
- Double-Extortion Tactics: Threats to delete decryption keys or leak data unless ransoms are paid in crypto.
Impact:
- Severe Disruptions: Virtual networks become inaccessible, causing major operational downtime.
- Massive Lost Revenue: Ransoms can reach multi-million USD levels.
- Data Exfiltration Risk: Attackers may steal sensitive VM data before encryption.
Delocker Attack on Windows Servers
Delocker also extensively targets traditional Windows Server environments—often central to business operations.
Attack Strategy:
- Weak Configuration Exploits: Malicious actors use RDP misconfigurations or unpatched vulnerabilities for access.
- Strong Encryption Mechanisms: Files encrypted using AES and secured with RSA-backed keys.
- Pressure Through Ransom Notes: Victims are coerced to pay in Bitcoin or other cryptocurrencies.
Consequences:
- Data Inaccessibility: Without backups or decryption tools, files remain locked.
- Operational Failure: Lack of access stalls business functions and triggers reputational damage.
- Loss of Trust: Stakeholders may lose confidence, and regulatory consequences may follow.
Using the Delocker Decryptor Tool
Follow these steps for data recovery using the decryptor:
- Secure the Tool: Reach out via email or WhatsApp to purchase and receive tool access.
- Run as Admin + Internet Required: Connect online so your tool can communicate with secure servers.
- Enter Your Victim ID: Provided in the ransom note to link files to your specific decryption key.
- Begin Decryption: Start the process—restoring encrypted files to their original state.
- Monitor Integrity: Verify file correctness post-decryption and maintain periodic backups.
Spotting a Delocker Ransomware Infection
Early detection is key. Watch for:
- Unusual File Extensions: Files renamed to .delocker1, .delocker20, etc.

Delocker’s Encryption Mechanisms
Delocker uses a combination of encryption techniques:
- AES (Symmetric): Fast, reliable encryption engine.
- RSA (Asymmetric): Ensures encrypted files can only be decrypted with attacker-held private keys.
Who Is at Risk?
Delocker has affected diverse sectors—healthcare, finance, education—undermining services, finances, and public trust.
Attack Lifecycle of Delocker Ransomware
- Initial Entry: Via phishing, RDP, or software exploits.
- Lateral Movement: Spreads through a compromised network.
- Data Encyption: Locks files on workstations and servers.
- Extortion Delivery: Victims get ransom notes threatening deletion or leakage.
- Final Negotiations: Payment, decryption, or data loss ensues.
Preventive Best Practices
Free & Alternative Recovery Methods
If you’re unable to use the Delocker tool, consider:
- Free Decryptors: Explore resources like NoMoreRansom, Emsisoft, Avast, Kaspersky.
- Restoring from Backup: Use offline or off-site backups.
- Volume Shadow Copies / System Restore: Leverage Windows built-in recovery options.
- Data Recovery Tools: Use programs like Recuva, PhotoRec, etc.
Consequences of a Delocker Attack
Infections can mean:
- Severe downtime and data loss
- Direct and indirect financial costs
- Reputational damage and compliance fallout
- Loss of intellectual property and sensitive data
Verification: Tools and Decryptor Limitations
Remember: free and commercial decryptors vary in coverage. Only certain ransomware versions have known flaws that enable decryption. Always verify compatibility and avoid downloading tools from unverified sources.
Conclusion
Delocker ransomware is a sophisticated and aggressive threat, especially to virtualized and server-based environments. By combining strong defense measures—patched systems, secure access, backups—with prompt detection and a focused recovery plan like the Delocker Decryptor, organizations can neutralize the impact and avoid paying extortion. Stay vigilant and prepared: cybersecurity is your strongest defense.
