.enc / .iv / .salt Ransomware Decryptor
Our cybersecurity specialists have crafted a tailor-made decryptor capable of handling ransomware strains that append .enc, .iv, and .salt extensions to encrypted data. This malicious software is known for targeting Windows, Linux, and VMware ESXi servers. The tool is optimized for both speed and reliability, ensuring corrupted files are avoided and maximum recovery is achieved.
How the Recovery Mechanism Works
The decryption process blends AI-driven algorithms with blockchain-based validation, ensuring file integrity throughout every stage of recovery. Each compromised environment typically contains a ransom note with a unique login ID, which our decryptor references to align with the encryption keys used by the attackers. Even in scenarios where the ransom note is missing, we provide an upgraded recovery module capable of addressing the most recent ransomware variations. To guarantee safety, our solution first scans encrypted data in read-only mode before initiating recovery.
Requirements Before Starting the Decryption
To begin the recovery process, the following elements must be available:
- A copy of the ransom demand note named Instruction-For Decrypt-READ-ME.txt
- A small batch of encrypted files for testing
- Administrator privileges on the infected system
- An active internet connection to perform secure verification
First Response After Infection
Once ransomware activity is detected, swift containment is essential. Disconnect the impacted systems from the broader network to stop further spread. Encrypted files, ransom notes, and forensic evidence such as logs or traffic captures should be preserved. Victims should avoid rebooting, as restarting may trigger further encryption scripts. Above all, organizations should avoid random online “free decryptors” from untrusted forums, as these frequently result in irreversible damage.
Available Recovery Paths and Decryption Methods
Free Alternatives
Community Tools for Old Variants
Earlier ransomware samples that used only .enc extensions were occasionally vulnerable to weaknesses in cryptography. Researchers created community-made decryptors for these strains. However, with the introduction of accompanying .iv and .salt metadata files, these loopholes have been patched, leaving modern variants immune to those free tools.
Restoration via Backups
Organizations that routinely maintain offline or offsite backups have the safest option. These should be checked carefully before use, as some attackers attempt to tamper with stored backups. Technologies like immutable storage or snapshot-based recovery provide strong resilience.
Virtualized Environment Rollbacks
In VMware or Hyper-V infrastructures, pre-attack snapshots can be reverted to restore functionality. As with backups, validation is necessary to confirm that attackers have not corrupted or erased these snapshots.
Paid Solutions
Paying Cybercriminals Directly
When victims comply with ransom demands, the attackers typically send back a decryptor tool tied to the victim’s ransom note ID. Unfortunately, this method carries high risk — there is no guarantee that the attackers will provide a working tool, and sometimes their decryptors contain backdoors or incomplete recovery capabilities.
Negotiating Through Specialists
Professional negotiators occasionally handle ransom discussions. These experts may succeed in lowering ransom amounts or confirming whether attackers hold genuine decryption keys. However, the service is often costly and can delay recovery.
Our Proprietary Decryptor
Unlike relying on criminals, our engineered decryptor leverages reverse-engineering breakthroughs and operates inside a controlled sandbox. Every recovery session is logged, ensuring transparency. This guarantees safe recovery while avoiding scams or hidden malware inside attacker-supplied tools.
Structured Guide to File Recovery
- Verify infection by checking file extensions (.enc, .iv, .salt) and confirming the ransom note’s presence.
- Isolate infected machines and halt encryption scripts.
- Submit sample files and ransom notes to our experts for an evaluation.
- Launch the decryptor with admin rights once instructions are provided.
- Input victim ID codes from the ransom note to align decryption keys.
- Recovery initiates, with files restored to their original state.
Recovery Options: Online vs. Offline
For environments that cannot connect to the internet, offline decryption is available, where encrypted files are transferred for recovery in a secure manner. Online recovery, on the other hand, provides faster turnaround with end-to-end encryption ensuring full confidentiality. Both pathways are compatible with our decryptor.
Technical Breakdown of the Malware
This ransomware family employs a multi-layer encryption approach. File contents are renamed with .enc, initialization vectors are stored separately as .iv, and salts are maintained in distinct .salt files. This structure significantly raises the difficulty of brute-force decryption. Victims also find ransom notes named Instruction-For Decrypt-READ-ME.txt, which typically direct them to anonymous TOR-based communication channels.
Attack Vectors and Tools Employed
Threat actors infiltrate targets by exploiting unpatched vulnerabilities, brute-forcing weak remote access credentials, and spreading phishing emails. VPN flaws and exposed RDP endpoints are common entry points. Once inside, attackers deploy a wide toolkit:
- Mimikatz – Extracts plaintext credentials, password hashes, and Kerberos tickets to aid lateral movement.
- LaZagne – Retrieves stored credentials from browsers and applications.
- SoftPerfect Network Scanner – Maps live hosts and shared resources in the environment.
- Advanced IP Scanner – Locates accessible devices and shared admin resources.
- RClone – Syncs stolen files with cloud storage, avoiding detection.
- Mega.nz – Provides encrypted cloud storage for exfiltrated data.
- Ngrok – Creates hidden tunnels for remote command-and-control.
- AnyDesk – Ensures persistent remote desktop access while masquerading as legitimate IT usage.
- AdFind – Collects Active Directory data for privilege escalation.
- PCHunter64 – Offers low-level control over processes and security features.
- Zemana (BYOVD misuse) – Exploited for kernel-level access to bypass defenses.
- PowerTool – Functions as a rootkit, concealing attacker activity.
Collectively, these utilities enable attackers to conduct credential theft, reconnaissance, persistence, exfiltration, and stealth, making their campaigns extremely difficult to contain.
Encryption and Ransom Tactics
The ransomware applies hybrid cryptography, typically pairing ChaCha20 or AES for file-level encryption with RSA for key protection. Local shadow copies and backups are erased to block easy recovery. Beyond encryption, adversaries practice double extortion, threatening to leak sensitive data if the ransom is not paid.
Indicators of Compromise (IOCs)
- File extensions .enc, .iv, .salt appearing throughout systems
- Connections to Ngrok, AnyDesk, or Mega.nz services
- Ransom notes titled Instruction-For Decrypt-READ-ME.txt
- Malware often running from temporary directories
- System artifacts related to process tampering and shadow copy deletion
Strengthening Defenses
Enterprises can limit exposure by enabling multi-factor authentication on VPNs, patching software promptly, and segmenting networks. Monitoring unusual traffic, disabling unnecessary remote services, and applying kernel-level protection are also crucial. Long-term security requires real-time monitoring and continuous threat detection.
Victim Impact and Trends
This ransomware disproportionately targets manufacturing, finance, healthcare, education, and government organizations. The most heavily impacted nations include the United States, Germany, Canada, and India.
