How It Works?
AI + Blockchain Analysis: A secure cloud-based platform evaluates encrypted files, while blockchain ensures integrity of the recovery chain.
Login ID-Based Mapping: Each ransom note includes a unique victim ID (e.g., YyGv93gHIaY58kPdF1jJ1mvsP3WXJ3GOZZf3SNciGFQ*7ga9lt4bur7). Our engine uses this to align files with their encryption batch.
Universal Key (Optional): For variants where ransom notes are missing, our premium decryptor handles random extension-based Mimic strains.
Secure Execution: The process begins with read-only scans to analyze file states, ensuring no accidental corruption before attempting recovery.

Requirements
- A copy of the ransom note (Decrypt_files.txt)
- Access to encrypted files with extensions like .7ga9lt4bur7, .giapk33vw, .GREEDYFATHER, etc.
- Internet connection for cloud-assisted processing
- Administrator rights (local or domain)
Immediate Steps to Take After a Mimic/Pay2Key Ransomware Attack
Disconnect Immediately
Isolate infected systems from the network to prevent lateral spread across shared drives, servers, and backups.
Preserve Everything
Do not delete ransom notes or encrypted files. Preserve logs, event dumps, and forensic artifacts, as attackers often clear Windows Event Viewer to hide traces.
Immediately Shut Down Compromised Systems
Avoid reboots that may re-trigger encryption scripts. Never format encrypted disks before proper evaluation.
Contact a Ransomware Recovery Expert
Do not attempt DIY decryption from shady forums. Trusted professionals can assess your exact variant and improve chances of recovery.
How to Decrypt Mimic/Pay2Key Ransomware and Recover Your Data?
Mimic (aka Pay2Key) is a destructive double-extortion ransomware group known for rapid encryption and large-scale corporate compromises. If you’re affected, our engineered Mimic Decryptor and forensic approach can restore files safely without ransom payment.
Mimic/Pay2Key Decryption and Recovery Options
Free Methods
Backups Restore
The cleanest path remains restoring from offline/offsite backups. Always validate snapshots before rollback to avoid partial corruption.
VM Snapshots
VMware ESXi and Proxmox snapshots can help revert systems to pre-attack states. Verify logs, since attackers sometimes delete snapshots if they gain vCenter access.
Researcher Tools
While there is no universal decryptor, researchers recommend hunting for artifacts with YARA rules and using forensic utilities to check for partial unencrypted remnants. Utilities like Everything.exe (ironically abused by attackers) can also help administrators map affected file trees.
Paid Methods
Paying the Ransom
Attackers demand contact via email addresses such as mikazeg@onionmail.org or cabasetra2030@onionmail.org. Payment theoretically delivers a decryptor tied to the victim’s personal ID. Risks include partial recovery, corrupted files, or hidden backdoors.
Third-Party Negotiators
Negotiators may lower ransom demands and validate decryptors with test files. However, fees are high and results uncertain.

What is Mimic/Pay2Key Ransomware?
Mimic (often linked to Pay2Key) is a Ransomware-as-a-Service (RaaS) strain. It encrypts files quickly across corporate networks, while threatening to leak stolen data if ransoms go unpaid. Victims report simultaneous multi-host infections within minutes.
Notable Traits
- Extensions: Random strings or identifiers, e.g., .7ga9lt4bur7, .giapk33vw, .GREEDYFATHER.
- Ransom Notes: Always Decrypt_files.txt. IDs contain long alphanumeric strings followed by *<extension>.
- Double Extortion: Attackers claim to exfiltrate employee data, financial records, and network maps.
- Event Log Clearing: Victims report Event Viewer logs wiped post-encryption.
Link to Pay2Key & Affiliations
- Shares ransom-note structure, victim ID formatting, and contact patterns with Pay2Key.
- Uses known lateral-movement tools (PsExec, Process Hacker, IObit Unlocker, Everything).
- Known to exfiltrate data to Mega.nz, Ngrok.io, and private I2P leak sites.
How Mimic/Pay2Key Works: The Inside Look
Initial Access Vectors
- RDP brute force / credential theft
- Exploiting VPN gateways (unpatched appliances)
- Phishing for credentials
Tools, TTPs & MITRE ATT&CK Mapping
- Credential Harvesting: Mimikatz, LaZagne.
- Reconnaissance: Advanced IP Scanner, SoftPerfect Scanner.
- Defense Evasion: Process Hacker, Zemana, IObit Unlocker.
- Data Exfiltration: FileZilla, RClone, Mega, Ngrok, AnyDesk.
- Encryption & Anti-Recovery: ChaCha20/AES + RSA/ECC hybrid. Shadow copies deleted via vssadmin delete shadows /all /quiet.
Known Mimic/Pay2Key Indicators of Compromise (IOCs)
File Extensions
- .7ga9lt4bur7
Ransom Note
- Always named Decrypt_files.txt

- cabasetra2030@onionmail.org
Other Known Mimic/Pay2Key File Extensions and Variants
While the .7ga9lt4bur7 extension is a confirmed marker of Mimic/Pay2Key ransomware, multiple other extensions have been observed in the wild. These unique identifiers appear in the ransom note after the victim ID and are also appended to encrypted files.
Extracted Extensions from Ransom Note Samples
- .9niOpX
- .giapk33vw
- .ul8dlsj86v
- .ELPACO-team
- .datastore@cyberfear.com
- .GREEDYFATHER
- .dataland
- .decryptboss@gmail.com.terminator
Pattern Observations
- Alphanumeric tokens: Short or long random strings (e.g., .9niOpX, .ul8dlsj86v).
- Named identifiers: Custom group tags or keywords (e.g., .GREEDYFATHER, .ELPACO-team).
- Email-based extensions: Some IDs use attacker emails directly (e.g., .datastore@cyberfear.com, .decryptboss@gmail.com.terminator).
- ID separator: Always follows an asterisk * in the ransom note’s personal ID field (e.g., YyGv93gHIaY58kPdF1j…*7ga9lt4bur7).
Why It Matters?
These extensions serve dual purposes:
- Victim Identification — They help attackers track victims uniquely across campaigns.
- Decryption Key Mapping — The extension token corresponds with the victim’s encryption batch, ensuring only the matching decryptor can unlock the files.
Mitigations and Best Practices
- Secure Remote Access — MFA on VPN and RDP. Disable unused services.
- Patch and Update — Fix known VPN and firewall CVEs.
- Prevent BYOVD Attacks — Block unsigned driver installs.
- Network Segmentation — Separate critical servers from user endpoints.
- Continuous Monitoring — SOC/MDR should detect PsExec, Process Hacker, and outbound traffic to Mega.nz/Ngrok.

What are the dangers of leaking your company’s data.
First of all, you will receive fines from the government such as the GDRP and many others, you can be sued by customers of your firm for leaking information that was confidential. Your leaked data will be used by all the hackers on the planet for various unpleasant things. For example, social engineering, your employees’ personal data can be used to re-infiltrate your company. Bank details and passports can be used to create bank accounts and online wallets through which criminal money will be laundered. On another vacation trip, you will have to explain to the FBI where you got millions of dollars worth of stolen cryptocurrency transferred through your accounts on cryptocurrency exchanges. Your personal information could be used to make loans or buy appliances. You would later have to prove in court that it wasn’t you who took out the loan and pay off someone else’s loan. Your competitors may use the stolen information to steal technology or to improve their processes, your working methods, suppliers, investors, sponsors, employees, it will all be in the public domain. You won’t be happy if your competitors lure your employees to other firms offering better wages, will you? Your competitors will use your information against you. For example, look for tax violations in the financial documents or any other violations, so you have to close your firm. According to statistics, two thirds of small and medium-sized companies close within half a year after a data breach. You will have to find and fix the vulnerabilities in your network, work with the customers affected by data leaks. All of these are very costly procedures that can exceed the cost of a ransomware buyout by a factor of hundreds. It’s much easier, cheaper and faster to pay us the ransom. Well and most importantly, you will suffer a reputational loss, you have been building your company for many years, and now your reputation will be destroyed.
Do not go to the police or FBI for help and do not tell anyone that we attacked you.
They won’t help and will only make your situation worse. In 7 years not a single member of our group has been caught by the police, we are top-notch hackers and never leave a trace of crime. The police will try to stop you from paying the ransom in any way they can. The first thing they will tell you is that there is no guarantee to decrypt your files and delete the stolen files, this is not true, we can do a test decryption before payment and your data will be guaranteed to be deleted because it is a matter of our reputation, we make hundreds of millions of dollars and we are not going to lose income because of your files. It is very beneficial for the police and the FBI to let everyone on the planet know about the leak of your data, because then your state will receive fines under GDPR and other similar laws. The fines will go to fund the police and FBI. The police and FBI will not be able to stop lawsuits from your customers for leaking personal and private information. The police and FBI will not protect you from repeat attacks. Paying us a ransom is much cheaper and more profitable than paying fines and legal fees.
If you do not pay the ransom, we will attack your company again in the future.
Conclusion: Restore Your Data, Reclaim Your Network
Mimic/Pay2Key ransomware is fast-moving, destructive, and extortion-driven. But with the right recovery steps, data restoration is achievable. Avoid unverified tools and fake decryptors. Trusted decryption and IR specialists improve recovery chances and minimize downtime.
