How It Works?
We pair AI‑assisted reverse engineering with validated threat‑intelligence workflows to process your encrypted data securely in the cloud. A victim-specific Decryption ID from your ransom note maps to your encryption batch. If that ID is unavailable, our Universal Key option works with up‑to‑date Mimic variants like ELENOR‑corp v7.5. The decryptor first scans files in read‑only mode to assess which are recoverable, then executes controlled decryption.

How to Decrypt Mimic Ransomware and Recover Your Data?
Mimic (also known as N3ww4v3) is a high‑impact ransomware variant first seen in June–July 2022. It abuses the Everything.exe API for rapid file discovery and encryption, disables backups, and prevents shutdowns. Its aggressive extensions—such as .QUIETPLACE or .HALE‑<ID>—match the embedded Decryption ID with an asterisk. Our decryption tool exploits known cryptographic and behavioral flaws in recent versions, enabling safe recovery across Windows, ESXi, and Linux environments.
Mimic Ransomware Recovery Options: What Works and What Doesn’t
Free Methods
1. Avast Decryptor and Other Free Tools
Free decryptors developed for early Mimic variants—such as the Avast tool—work only on ransomware strains active before August 2023. These legacy versions used weak or static encryption keys, which made decryption technically feasible without paying the ransom.
However, newer versions like ELENOR-corp v7.5 or ELPACO-team v6.3 use a hybrid encryption model that combines ChaCha20 with RSA, rendering most free tools ineffective. Using a legacy decryptor on modern strains may result in failure or data corruption. These tools typically run offline and do not require internet access, making them suitable for sandboxed environments—but only if you’re sure the variant is an older one.
2. Restoring from Backups
Restoring from a clean, offline backup is considered the safest and most reliable method of recovery. This assumes your backup system was not reached or encrypted by the ransomware. Mimic is known to scan connected drives and backup paths, often deleting volume shadow copies or targeting backup servers directly.
For backup recovery to succeed, backups must be verified for integrity using checksums or by mounting them in a test environment. Partial encryption or backup system compromise may result in failed restores or reinfection if overlooked.
3. Virtual Machine Snapshots
In virtualized environments like VMware ESXi or Proxmox, reverting to pre-attack snapshots is often a fast and effective way to restore systems. If snapshots are automated and stored securely, they allow rollback to a clean state within minutes.
The catch is that if the attackers had access to your hypervisor (e.g., vCenter), they may have deleted or tampered with the snapshots. Snapshots should always be unmounted and checked for modification before applying a rollback. Retention policies and frequent snapshot intervals increase the chances of recovery.
Paid Methods
1. Paying the Ransom
This method gives you a chance to recover data using a decryptor provided by the attackers—usually tied to the unique Victim ID in your ransom note. In some cases, it may work as promised, restoring encrypted files effectively.
But this option comes with significant risks. There’s no guarantee the attackers will honor their promise. Even when they do, the decryptor might only work partially or could include backdoors that reopen access to your systems. Paying the ransom may also be illegal in some countries, and doing so can trigger regulatory or compliance violations, especially for healthcare or government organizations.
2. Engaging a Third-Party Negotiator
Professional ransomware negotiators can manage communications with threat actors on your behalf. Their experience helps validate the legitimacy of the ransomware group, reduce the ransom demand, and confirm decryption capabilities before payment.
While this can increase your odds of a successful outcome, it is also expensive and still does not guarantee results. Some attackers may simply take the money and disappear. Negotiators often charge a flat fee or a percentage of the ransom amount, adding financial overhead to an already costly incident.

Step‑by‑Step Mimic Recovery Guide with Our Decryptor
- Step 1: Identify the Infection
Look for ransom notes such as Decrypt_INFO.txt, Decrypt_me.txt, or similar files. Also, check for unusual file extensions like .HALE‑MX…, which indicate that encryption has occurred. - Step 2: Isolate Affected Systems
Immediately disconnect the infected machines from the internet and local networks. This will prevent the ransomware from spreading to other devices, servers, or backups. - Step 3: Freeze Network Activity
Halt any ongoing operations on compromised systems. Avoid restarting or shutting down devices, as this could trigger further encryption or damage. - Step 4: Collect and Submit Samples
Send a sample encrypted file along with the ransom note to our response team. This helps in accurately identifying the Mimic variant affecting your systems. - Step 5: Receive Variant Confirmation
Our experts will analyze the samples and confirm the exact variant and encryption behavior, allowing for tailored decryption. - Step 6: Launch Our Decryptor Tool
Run the decryptor with administrative privileges on the affected system. Ensure that internet access is available for cloud-based analysis and decryption. - Step 7: Input Your Victim ID
Extract the unique victim ID from your ransom note and enter it into the decryptor when prompted. This ID maps to your specific encryption instance. - Step 8: Begin Secure Decryption
Start the decryption process. The tool will scan and safely decrypt files without altering original metadata until decryption is fully complete.

Offline vs Online Decryption Methods
Offline methods suit air‑gapped or highly restricted environments: no need for internet, and recovery happens locally using physical media. Online methods via our tool offer faster turnaround and expert support, using encrypted channels and blockchain‑verified logs for integrity validation.
What is Mimic (N3ww4v3) Ransomware?
Mimic is a stealthy ransomware‑as‑a‑service (RaaS) family traced back to the leaked Conti builder in mid‑2022. Known for combining Everything API abuse with encryption acceleration and defense evasion, it targets entire infrastructures swiftly—especially business, healthcare, and government environments. Examples include ELPACO‑team version 6.3 and ELENOR‑corp version 7.5, which added credential harvesting and data exfiltration pre‑encryption.
Technical Overview: How Mimic Operates
- Initial Access
Attacks often begin via brute‑force against MSSQL servers (RE#TURGENCE campaign), exposed RDP endpoints, or phishing campaigns. Tools like Mimikatz and Clipper malware have been used for credential harvesting. - File Discovery & Encryption
Mimic drops legitimate components such as Everything.exe, Everything DLLs, and svhostss.exe to enumerate files quickly via the Everything API, then encrypts them with hybrid ChaCha20/RSA and deletes shadow copies. - Defense Evasion
Ransomware disables Windows Defender and telemetry, prevents system shutdowns, terminates security processes, and uses registry persistence. - Extortion
Encrypted files carry unique extensions like .HALE‑MX…, matched to a ransom note containing Decryption ID with an asterisk (*). Double extortion tactics are common: leaking stolen data if ransom is unpaid.
Indicators of Compromise (IOCs)
Mimic ransomware infections leave behind a variety of system-level and file-based artifacts that can serve as strong indicators of compromise. Most notably, the encryption appends file extensions like .HALE‑<ID>, which are linked to the victim-specific Decryption ID in the ransom note. These notes are often named Decrypt_INFO.txt, Decrypt_me.txt, or Readme_Mimic.txt, containing unique identifiers and payment instructions.
The ransom note contains the following message for the victims:
Hello my dear friend (Do not scan the files with antivirus in any case. In case of data loss, the consequences are yours)
Your data is encrypted by HALE
Your decryption ID is MXstg3E9VcUadqKdSGo0bsPDR29kp–ysowf5skGAF4*HALE-MXstg3E9VcUadqKdSGo0bsPDR29kp–ysowf5skGAF4

Infected systems may also display hidden or new disk partitions such as \a or \b, along with disabled system functionality—most notably, the shutdown button or task manager may become non-functional.
Artifacts commonly found include:
- mimic_log.txt or debug_log.txt, logging encryption progress
- Session.tmp, possibly recording active session metadata
- Disabled shadow copies and Windows Defender
- Blocked registry editor or recovery tools
- Unusual outbound traffic to file transfer services
These anomalies, especially when combined, point strongly to a Mimic or N3ww4v3 ransomware breach.
Tools Used by Mimic (N3ww4v3) Ransomware
Mimic operators rely on a blend of open-source, legitimate, and malicious utilities to infiltrate, map, and cripple the victim’s infrastructure. Below are the key tools they use, categorized by function:
- Everything.exe
Used to enumerate all files on a system rapidly. Mimic abuses this file search utility via its API to identify data for encryption without triggering security alerts. - Everything32.dll / Everything64.dll
Supporting libraries for Everything.exe. These DLLs are often dropped together with the executable and are used based on the system architecture. - Mimikatz
An open-source tool that extracts plaintext passwords, hashes, PINs, and Kerberos tickets from memory. It’s widely used for credential harvesting. - LaZagne
Another credential stealer focused on extracting stored credentials from browsers, mail clients, and password managers on compromised systems. - AdFind
Used for Active Directory enumeration. This helps attackers map out the network, discover domain controllers, and identify user privileges. - SoftPerfect Network Scanner
A network exploration tool that scans for live hosts, open ports, and available services. It aids in lateral movement within a corporate environment. - Advanced IP Scanner
Another scanning utility used to gather a list of reachable machines and services, especially helpful in large networks with minimal segmentation. - RClone
A command-line tool that syncs files to cloud storage services. It’s used by attackers for exfiltrating stolen data before encryption. - FileZilla
An FTP client used to manually or script transfer stolen files to external servers. - Ngrok
Establishes secure tunnels from the internal network to remote systems. It allows attackers to bypass firewall and NAT restrictions for persistent remote access. - AnyDesk
A legitimate remote desktop utility that Mimic actors install to retain stealth access to systems, even post-encryption. - PowerTool
A known rootkit management utility used to hide processes and services from system monitoring tools, aiding in evasion. - Zemana AntiLogger (Driver Abuse)
Used in BYOVD (Bring Your Own Vulnerable Driver) attacks. Mimic drops and exploits this outdated software to disable or circumvent antivirus and EDR protections.
