How Our Recovery Decryptor Works?

The Charon recovery tool integrates several protective and analytical layers. It is not just a brute-force decryptor but a comprehensive restoration system:

• Encryption Mapping via Victim ID: Every ransom note dropped by Charon contains a victim-specific identifier. Our decryptor uses this unique marker to align the decryption batch with the infected system.
  
• AI-Powered Cloud Analysis: Encrypted files are securely processed through a sandboxed cloud engine that examines Charon’s key structure while ensuring no secondary payloads remain active.
  
• Blockchain Verification Layer: The decrypted output is checked against blockchain-based integrity validators, ensuring no tampering occurs during the process.
  
• Optional Universal Decryption Module: In situations where ransom notes are missing or partial, we provide an enhanced universal tool designed to tackle the latest Charon builds.

Essential Requirements Before Decryption

Before launching the decryptor, certain prerequisites must be fulfilled. This ensures accuracy and prevents data loss:

• A copy of the ransom note (“How To Restore Your Files.txt”).
  
• Access to encrypted files with the “.Charon” extension.
  
• Administrator privileges on the compromised system.
  
• A stable internet connection for secure server-side analysis.
  

Immediate Actions After a Charon Attack

The first hours after discovering a Charon infection are critical. Correct handling of the system greatly increases recovery chances.

• Cut Off Network Connectivity: Disconnect the affected device from LAN and Wi-Fi immediately to stop the spread across drives and servers.
  
• Preserve Every Artifact: Do not delete ransom notes, logs, or encrypted files. These items are essential for both forensic analysis and successful decryption.
  
• Do Not Reboot: Restarting the compromised machines may trigger additional scripts, worsening the situation.
  
• Seek Professional Support: Avoid unverified decryptors from forums or dark web sources. Instead, consult with trusted recovery experts to evaluate the infection and initiate safe restoration.
  

Understanding Charon’s Tactics

Charon ransomware uses DLL side-loading to enter systems, exploiting legitimate executables such as “Edge.exe” to introduce its malicious library “msedge.dll”. Once inside, it disables running services, terminates security tools, and removes shadow copies to eliminate recovery options. Its encryption covers both local drives and network-shared folders. In most cases, it demands ransoms around $500,000 USD in Bitcoin, threatening permanent loss of access and public data leaks if demands are ignored.

File Decryption and Recovery Approaches

There are several pathways to recovering files locked by Charon ransomware. The effectiveness of each depends on the infection variant and environment.

Free Alternatives

Backup Restoration: If secure offline or off-site backups exist, they provide the cleanest route to full recovery. Validation checks such as checksums must be run to ensure the backups weren’t corrupted during the attack.
Shadow Copies (Rarely Available): While Charon typically deletes shadow copies, in some cases partial recovery may still be possible if the deletion process was incomplete.

Professional Solutions

Custom Charon Decryptor: Our engineered solution is designed to bypass Charon’s encryption through structural weaknesses identified during reverse-engineering. It has been successfully deployed in real-world recovery scenarios.
Cloud-Assisted Recovery: Files can be analyzed and decrypted within a secure cloud environment, returning clean and verified copies.

Paid Options (Not Recommended)

Paying the ransom may sometimes result in a decryptor from the attackers, but there are no guarantees. Many victims have reported receiving either corrupted recovery tools or no key at all. Additionally, payment encourages further criminal activity.

Step-by-Step Recovery Using Our Decryptor

1. Collect sample encrypted files and the ransom note.
   
2. Disconnect compromised systems from all networks.
   
3. Submit files to our secure portal for analysis.
   
4. Run the Charon Decryptor with administrator rights.
   
5. Enter the victim ID from the ransom note.

Tools, Tactics & Indicators of Charon Ransomware

Charon ransomware operators rely heavily on a blend of publicly available tools, custom malware scripts, and administrative utilities to compromise systems, evade detection, and encrypt valuable data. Their playbook aligns closely with MITRE ATT&CK techniques, making them a persistent and highly adaptable threat.

Credential Access and Harvesting

One of the earliest objectives of Charon attackers is credential theft. By gaining administrative access, they ensure deep penetration into the victim’s environment.

Common tools include:

• Mimikatz – Extracts Windows credentials directly from memory and the LSASS process.
  
• LaZagne – Collects stored passwords from browsers, email clients, and system stores.
  

---

Reconnaissance and Network Mapping

Before launching full-scale encryption, attackers conduct wide scans to understand the network layout and identify valuable assets.

Frequently used tools:

• SoftPerfect Network Scanner – Detects active hosts, open ports, and shared folders.
  
• Advanced IP Scanner – Provides visibility of connected devices and accessible services.
  

---

Defense Evasion and Persistence

Charon uses legitimate software to bypass defenses, blending in with normal system processes.

• Zemana AntiMalware Loader – Exploited to load vulnerable drivers, bypassing endpoint security.
  
• PowerTool & PCHunter64 – Utilities that manipulate system internals, processes, and kernel structures to evade antivirus detection.
  

---

Data Exfiltration

Before encryption begins, data theft is performed to strengthen extortion attempts. Stolen data is later used for double extortion, where attackers threaten public leaks.

Exfiltration tools include:

• FileZilla / WinSCP – For manual FTP or SCP transfers.
  
• RClone & MegaSync – To push large volumes of stolen data to cloud storage providers.
  
• Ngrok & AnyDesk – To maintain persistence and exfiltrate data over hidden tunnels.
  

---

Encryption & Destruction

The final stage of the Charon attack involves paralyzing systems and locking files.

• ChaCha20 + RSA Hybrid Encryption – Files are encrypted rapidly with ChaCha20, while RSA protects encryption keys, ensuring decryption is impossible without the attacker’s key.
  
• Shadow Copy Removal – Commands like vssadmin delete shadows /all /quiet are executed to remove Windows Volume Shadow Copies.
  
• File Extensions – Encrypted files are renamed with “.charon” extensions, confirming compromise.
  

---

Indicators of Compromise (IOCs)

Charon ransomware leaves several footprints that can be used for detection and prevention.

• File Extensions: .charon on all encrypted files.
  
• Ransom Note: A text file often named charon_readme.txt, containing payment instructions and victim ID.
  
• Suspicious Processes: Execution of tools like mimikatz.exe, ngrok.exe, rclone.exe.
  
• Outbound Traffic: Connections to cloud storage services such as mega.nz, TOR nodes, and Ngrok tunnels.
  
• Registry & Services: Unusual driver loads or registry modifications from Zemana or PowerTool usage.
