- Stable internet connection for cloud-based modules
Immediate Steps After a JustIce Ransomware Attack
Disconnect Immediately
Isolate affected machines and backups from the network to block further spread of encryption threads.
Preserve All Evidence
Retain the ransom note, sample encrypted files, logs, and network data dumps. Avoid renaming or modifying files—they may become permanently unrecoverable.
Avoid Reboot or Format
Shutting down power is safer than rebooting. Restarting or formatting may trigger secondary encryption or overwrite remnants.
Engage a Ransomware Recovery Expert
Avoid DIY decryptors from forums—these often fail or inflict more damage. Early professional involvement increases the odds of fully restoring data.
How to Decrypt JustIce Ransomware and Recover Data?
JustIce emerged as a disruptive cryptovirus that appends .JustIce to files, locks access, changes desktop wallpaper, and displays a ransom demand instructing victims to email dr.sinaway@gmail.com. Our specialized decryptor is crafted to reverse JustIce’s weak encryption logic and restore access without paying ransom.
Decryption and Recovery Options
Free Methods
Generic Free Decryptor
How It Works?
Currently, there is no official free decryptor for JustIce ransomware. Researchers are analyzing encryption samples and the ransom payload, but no public release has been made. If the ransomware’s encryption logic shows flaws or a set of private keys is exposed, a decryptor may surface in future updates.
No Support for New Variants
JustIce’s encryption modules continue to evolve, and variants seen in mid-2025 use strengthened file handling routines and randomized keys, making earlier reverse-engineering strategies ineffective. Generic decryptors from other families (like STOP/Djvu or REvil) will not work here and may further damage encrypted files.
Local Execution Risks
While some victims attempt using legacy decryption utilities in sandbox environments, applying unverified decryptors may overwrite critical file headers or introduce corruption. It’s essential to wait for a JustIce-specific solution before running any tool against live samples.
Backup Restore
How It Works?
Backups stored offline, isolated, or in immutable storage remain the safest and fastest way to recover from a JustIce ransomware infection. If these backups were not encrypted or deleted during the attack, administrators can rebuild the affected infrastructure using clean pre-attack snapshots.
Integrity Verification
Before restoring, each backup should undergo a forensic review or checksum validation. Administrators must ensure that ransomware encryption wasn’t already underway during backup creation. Partial encryption or shadow copying may silently compromise backup integrity.
Immutable Storage Advantage
Technologies like WORM storage, air-gapped backup servers, and cloud snapshots with strict retention and access control offer organizations the best defense. When paired with network segmentation, they dramatically improve the odds of complete and clean recovery without paying a ransom.
Research-Based Methods
Timestamp‑Driven Brute‑Force (Experimental)
Researchers are exploring key recovery by brute-forcing predictable timestamp seeds inserted by JustIce during encryption, similar to ChaCha/RSA hybrid techniques. These tools are Linux-only and GPU-accelerated, requiring CUDA support and source compilation.
Behavioral Reversal on Sample Batches
Some local analysts have crafted scripts reversing JustIce’s key derivation algorithm for older variants where partial plaintext-ciphertext pairs are known.
Paid Methods
Paying the Ransom (Not Recommended)
Victims sometimes decide to pay after all else fails. This leads to:
- Victim ID verification when attackers provide a decryptor tied to the ID in README.txt.
- Risks: Non-functional tools, backdoors, partial recovery, or data corruption.
- Ethical/legal pitfalls: Encourages criminals, may violate local regulations, especially in government or healthcare.
Negotiators & Incident Response
Professional negotiators mediate TOR-based communication, request test decryptions, verify tool legitimacy, and handle ransom logistics. Their fees are high—often a flat rate or percentage—but success rates improve with expert coordination.

What Is JustIce Ransomware?
JustIce is a crypto-ransomware that encrypts almost all user-accessible files, appends .JustIce, changes the wallpaper to a ransom demand, and provides instructions via README.txt urging victims to contact attackers by email. It spreads through malicious email attachments, fake installers, cracked software, P2P networks, and compromised ads or websites. Once executed, it locks files swiftly and often disables system recovery options.

Ransom Note Dissected: What They Say and Why
If you discover a file named README.txt on your desktop or in multiple directories, stop immediately. Your system has likely been compromised by JustIce ransomware, and acting without a recovery plan may result in permanent data loss. The ransom note usually begins with a stark heading designed to intimidate:
———- JustIce Ransomware ———-
Your files have been encrypted using JustIce Ransomware!
They can only be decrypted by paying us a ransom in cryptocurrency.
Encrypted files have the .JustIce extension.
IMPORTANT: Do not modify or rename encrypted files, as they may become unrecoverable.

TTPs and Indicators of Compromise (IOCs)
Initial Access via Phishing, Cracked Tools, and Malvertising
JustIce primarily infiltrates systems through phishing emails that carry malicious attachments or embedded links leading to infected payloads. It also hides in pirated software, license key generators, and malicious ads on cracked download portals—making it a common threat among users seeking unauthorized software.
Execution Using Obfuscated Loaders and Encrypted Scripts
Once delivered, JustIce uses disguised executable files or encrypted scripts to initiate the encryption process. Often these executables are named similarly to common apps, deceiving users into clicking. Some variants may delay execution to evade sandbox detection or use batch files to trigger secondary scripts in memory.
Limited Persistence with Optional Payload Dropping
Unlike advanced threats, JustIce does not establish long-term persistence by default. It’s typically a single-run ransomware, executing its encryption script once. However, certain observed samples have dropped secondary malware such as password stealers or backdoors post-encryption, which continue to operate in the background.
Defense Evasion Through Volume Shadow Copy Deletion
To ensure victims cannot recover their files easily, JustIce disables Windows recovery by running commands that delete Volume Shadow Copies. These are removed silently using utilities like vssadmin, effectively erasing restore points before the user can act—leaving backups inaccessible from the infected device.
High-Impact Data Encryption and Visual Ransom Demand
Once encryption is complete, JustIce renames files with the .JustIce extension and replaces the desktop wallpaper with a branded ransom image. The wallpaper serves as a psychological trigger, while the README.txt ransom note provides communication instructions, typically demanding payment in cryptocurrency via email contact.
IOCs
- Encrypted files named *.JustIce with original extensions preserved.
- Presence of README.txt ransom note referencing dr.sinaway@gmail.com.
- Modified desktop wallpaper reading “JUSTICE RANSOMWARE” demanding payment.
- Disabled shadow copy / restore points in Windows (via vssadmin usage).
- Detection flags: Avast: Win64:Evo‑gen, Kaspersky: HEUR:Trojan‑Ransom.Win64.Generic, Microsoft: Ransom:Win64/PrinceRansom!rfn.
Tools Used by JustIce Ransomware
Here’s what’s known:
File Encryption Engine
JustIce uses a proprietary encryption routine that appends a .JustIce extension to victim files. There’s no public evidence it leverages common tools like ChaCha20 + RSA or known decryptor frameworks yet.
Shadow Copy Deletion
The ransomware disables Windows recovery by invoking commands such as vssadmin delete shadows /all /quiet, ensuring Volume Shadow Copies are removed to block restore functionality.
While detailed tool chains like credential dumpers or persistence frameworks haven’t been tied to JustIce in public analyses, its behavior mimics other crypto‑ransomware tools that are more light‑weight and focused solely on file locking and destruction of recovery mechanisms.
