Encrypted Ransomware Decryptor
The ransomware infection identified in this case modifies victim files by adding the .encrypted extension and leaves behind a ransom note titled readme.txt. The wording of this message mirrors language used in earlier “I hacked your email/device” scam campaigns, suggesting either code reuse or deliberate imitation. The note contains the threat actor’s contact email — [email protected] — along with a unique victim identification code: 2536412875215263336584.
The following digital fingerprints were submitted for one of the infected samples:
- SHA256: 9471D196908FA2750BE46F89E0B19880DE8B6EDF741BAB5EA53DF577B8D18A9D
- SHA1: 6A0BD8E2F689B53882A2C28B3EED31F50F8AF947
- MD5: 9894313C2E91939EBAFADE7598CF4BE8
The encrypted file’s header includes an encoded or base64-like string, while the victim confirmed isolating the infected device, producing read-only file copies, and uploading samples to ID-Ransomware, which returned “no known identification.”
Initial Recovery Avenues — Free Solutions
Free or public decryption methods can occasionally restore files if the attacker used an old or misconfigured encryption implementation. These should be attempted first, with exact forensic copies preserved.
1. Compare File Headers for Pattern Recognition
Check for recurring patterns or markers at the beginning of encrypted files. If uniform, researchers might generate a targeted decryptor. Submit samples with full metadata to NoMoreRansom, ID-Ransomware, or reputable antivirus vendors for renewed analysis.
2. Search for Legitimate Public Decryptors
Consult the official security portals of ESET, Avast, Kaspersky, and NoMoreRansom to see if any tools exist for .encrypted extensions. Avoid unverified decryptors from unofficial websites or anonymous forums.
3. Backup Restoration
Inspect offline and cloud backups. Always verify backup integrity using checksum validation or mount testing before restoring files. This prevents reintroducing hidden payloads or corrupted data.
4. Snapshot Rollback for Virtualized Systems
If you manage ESXi, Hyper-V, or similar virtual platforms, revert to a pre-attack snapshot—only after confirming that it wasn’t altered or deleted by the threat actor.
5. Advanced Forensic Key Recovery
Under controlled lab conditions, analysts can sometimes reconstruct keys by examining weak initialization vectors or captured encryption sessions. Only professionals should attempt this, as improper handling can permanently corrupt encrypted data.
Paid Recovery Options & Verified Decryptor Services
When public tools fail, organizations often pursue verified professional recovery methods. Below are the options—each with its benefits and potential risks.
Third-Party Negotiation Services
Specialized negotiators interact directly with attackers, validate proof-of-decryption samples, and sometimes reduce ransom amounts. While this path may restore operations faster, it often incurs high fees, and success rates vary depending on the threat actor’s reliability.
Direct Ransom Payment (Not Recommended)
Sending payment directly to criminals—such as to [email protected]—is strongly discouraged. Such actions can violate regional cybercrime laws, reinforce criminal funding, and carry no assurance that files will actually be decrypted.
Our Dedicated .encrypted Ransomware Decryptor
After extensive cryptographic investigation and live malware testing, our cybersecurity engineering team developed a specialized .encrypted Ransomware Decryptor. This tool is purpose-built for the strain associated with ransom emails from [email protected] and the victim ID 2536412875215263336584.
Our decryptor uses AI-driven key pattern modeling integrated with blockchain validation to recover data accurately and safely. Designed for individuals and corporate users alike, it operates inside a tightly controlled recovery framework to prevent reinfection and preserve forensic integrity.
Internal Design & Operational Workflow
1. Engineered via Reverse Analysis
Experts deconstructed the sample (SHA256: 9471D196908FA2750BE46F89E0B19880DE8B6EDF741BAB5EA53DF577B8D18A9D) to trace its encryption sequence and key generation logic. By analyzing file headers and matching victim IDs, they built an algorithm that reconstructs the encrypted key relationships unique to each infection.
2. Secure Cloud and Blockchain Verification
Encrypted files are processed in a quarantined, cloud-based sandbox. AI models test cryptographic permutations, while blockchain timestamping ensures every recovery step is immutable and verifiable.
3. Fraud Avoidance & Validation
Unverified “miracle” decryptors often rename or damage data. Our decryptor undergoes continuous external testing and begins with read-only scans before attempting any modifications. Every recovery session provides hash-based validation logs and digital recovery certificates.
Guided Recovery Process with the .encrypted Decryptor
Step 1 — Identify the Infection Scope
Ensure that all impacted files display the .encrypted extension and that each directory contains the ransom note readme.txt. Record:
- Contact Address: [email protected]
- Victim ID: 2536412875215263336584
Do not delete or alter these notes, as they are crucial for matching encryption batches.
Step 2 — Contain and Preserve Evidence
Disconnect affected systems immediately from both the internet and local networks. Retain encrypted samples, ransom notes, and logs on secure, write-protected storage. Avoid rebooting or reformatting devices.
Step 3 — Coordinate with Our Incident Response Team
Submit representative encrypted files (≤5 MB each), the ransom note, and the approximate time of compromise via our encrypted intake portal. The team confirms if the infection matches the identified .encrypted variant and provides a recovery schedule—typically within 24 hours.
Step 4 — Execute Controlled Decryption
Once verified, the decryptor can be safely deployed:
- Run the decryptor as Administrator for full directory access.
- Input the Victim ID (2536412875215263336584) to map to your encryption batch.
- Start the recovery process; logs and file checksums will generate automatically.
- Review restored data against original hash lists to confirm full integrity.
Security Controls & Validation Practices
The decryptor enforces strict operational safeguards:
- Read-only initial scanning prevents overwriting sectors.
- Immutable audit trails document every decrypted file.
- Blockchain proof-of-recovery guarantees authenticity.
- Automated quarantining isolates any residual trojans or malicious payloads.
Analysis of the Ransom Note & Threat Actor Profile
The ransom message emphasizes password theft, spyware installation, and data exposure, implying long-term system compromise. It demands payment within 72 hours and mimics social-engineering tone from previous global scams.
Below is the message as recovered from the victim system:
[Hello!
I’m a hacker who hacked your email and device a few months ago.
You entered a password on one of the sites you visited, and I captured it.
Of course, you can change it, or you already have.
But that’s okay, my malware updates it every time.
Don’t try to contact me or find me because I sent you an email from your account; it’s impossible.
I installed malicious code on your operating system through your email.
I recorded all your contact information with friends, colleagues, and relatives, as well as a complete history of your online visits.
I also installed a Trojan horse on your device and spied on you for a long time.
You’re not the only victim; I usually lock computers and demand ransom.
I expect payment from you to get your files back.
Pay with Bitcoin.
If you don’t know how, just Google “how to transfer money to a Bitcoin wallet.” It’s not difficult. After you receive the specified amount, all your data will be automatically deleted. My virus will also be deleted from your operating system.
My Trojan has an automatic warning; I’ll know about it after reading this email!
I’ll give you 3 days (72 hours) to pay.
If you don’t, all your connections and data will be lost!
And your device will be blocked (even after 72 hours) so you can’t block it.
Don’t be ridiculous!
The police or your friends will definitely not help you…
Note: I can offer you some advice for the future. Don’t enter your passwords on unsafe sites.
Contact: [email protected]
ID No: 2536412875215263336584
I hope you’ll be careful.
Farewell.]
The reuse of this wording suggests the threat actor adapted phishing or scam templates to appear more intimidating, possibly combining a trojan loader with basic file encryption.
