Immediate Response Steps for Solara Ransomware Victims
If you have discovered .solara files on your system, quick and careful action is critical to avoid further damage.
- Disconnect from Networks – Isolate the infected device to prevent ransomware from spreading across connected drives and systems.
- Preserve Encrypted Files & Notes – Keep read_it.txt and all .solara files intact, as they are essential for recovery attempts.
- Avoid Rebooting or Formatting – Restarting may trigger additional malicious scripts, while formatting can make data recovery impossible.
- Contact Cybersecurity Specialists – Professional recovery increases the chances of successful decryption without paying the ransom.
Solara Ransomware Data Decryption & Recovery Options
Solara ransomware uses a Chaos-based encryption mechanism that makes file recovery difficult without the proper keys. However, several recovery avenues are worth exploring, from free community-developed tools to professional-grade decryptors.
Free Recovery Methods
1. Existing Chaos-Based Decryptors
Since Solara is derived from the Chaos ransomware family, older Chaos decryptors may work on outdated Solara builds.
How It Works: Cybersecurity researchers have released tools that reverse early Chaos encryption flaws, particularly weak key generation. If Solara’s variant matches one of these vulnerable builds, the decryptor can restore .solara files without ransom payment.
Limitations: Modern Solara variants have improved key security, making older Chaos decryptors ineffective. Running an incompatible decryptor could cause partial or corrupted recovery.
2. Backup Restoration
How It Works: Restoring from unaffected offline or cloud backups remains the most reliable recovery method. This involves wiping the infected system, reinstalling the OS, and restoring clean data from backup storage.
Limitations: Backups connected to the infected system during the attack may also be encrypted. Always verify snapshot integrity before restoration.
3. Previous File Versions & Shadow Copies
How It Works: Windows systems often keep backup “shadow copies” of files. If Solara failed to remove them, these can be used to roll back to an earlier state. Tools like “ShadowExplorer” can retrieve these copies.
Limitations: Most Solara builds attempt to delete shadow copies using system commands, so this method only works if the deletion process failed or was interrupted.
4. Data Carving & Partial Recovery Tools
How It Works: Specialized forensic tools can scan disk sectors for recoverable file fragments, bypassing encryption by restoring unencrypted cached data.
Limitations: This method does not produce fully functional files for complex formats and works best for images, videos, and certain text files.
Paid Recovery Methods
1. Paying the Ransom
While this is technically an option, it is strongly discouraged.
How It Works: Victims send payment (Solara requests 50 PLN in Paysafecard or $5 in Bitcoin) to the attacker, who promises to provide a decryption tool linked to the victim’s unique ID in the ransom note.
Risks: There’s no guarantee the attacker will send a working decryptor. Some campaigns are incomplete or experimental, meaning no functioning recovery tool exists. Payment also supports cybercrime and may be illegal in certain jurisdictions.
2. Third-Party Negotiators
How It Works: Professional ransomware negotiators act as intermediaries between victims and attackers, aiming to reduce ransom amounts and verify decryptor legitimacy before payment.
Risks: Negotiators cannot guarantee full recovery and often charge high fees. In some cases, attackers still fail to deliver working keys.
3. Our Specialized Solara Decryptor
After extensive research into the Chaos-based encryption scheme used by Solara, our cybersecurity team developed a proprietary decryptor capable of restoring .solara files under supported conditions.
Steps to Use the Solara Decryptor:
- Collect Required Files – Have at least one .solara encrypted file and the ransom note read_it.txt ready.
- Isolate the Infected System – Disconnect the system from all networks to prevent further encryption.
- Install the Decryptor Tool – Download and install the Solara Decryptor on the affected system or a clean environment.
- Run as Administrator – Launch the tool with administrator privileges to allow full access to file directories.
- Load Encrypted Files – Select the folder containing .solara files for scanning.
- Enter Victim ID – Input the unique identifier from the ransom note for targeted key matching.
- Start the Decryption Process – Click “Start” to begin safe file restoration. Progress will be displayed in real time.
- Verify Recovered Files – After completion, open several restored files to confirm integrity before resuming normal system use.

Paying the Ransom – Risks & Considerations
Solara ransom notes demand Paysafecard payments in Poland (50 PLN) or $5 in Bitcoin. However, paying is not recommended because:
- There’s no guarantee of receiving a working decryptor.
- Some ransomware campaigns are incomplete or experimental, meaning the attacker may have no working recovery tool at all.
- Payments fund cybercrime and may be illegal in certain jurisdictions.
Understanding Solara Ransomware’s Behavior
File Encryption
Solara modifies files by adding the .solara extension, e.g., image.jpg becomes image.jpg.solara. It targets a wide range of file formats including documents, images, archives, and executables.
Ransom Note
The ransom note contains the following message:
Oh uh, your pc was hacked by Solara Ransomware!
How can i recover my files?
Almost no way! You tried to crack our software!How did this happen?
You flagged our anti crack and your HWID wasn’t in our database!Can i actually recover my PC?
Not really, only if you buy the decryption software from xenqxd on discord [he didn’t make this anti crack, he has the decryption software]What methods do you accept?
In poland – paysafecard [50 PLN]
Or 5 dollars in bitcoin
Tactics, Techniques, and Tools Used by Solara Ransomware
Solara ransomware leverages several well-known intrusion and encryption tactics, many of which are inherited from its Chaos ransomware base. Its operational playbook is fairly simple but effective, targeting unprotected systems through opportunistic infection methods.
1. Initial Access Techniques
- Malicious Email Attachments – Phishing emails disguised as invoices, software updates, or security alerts carry infected documents, executables, or archives.
- Trojanized Software Downloads – Cracked software installers and “keygens” often contain Solara payloads.
- Drive-By Downloads – Compromised websites or malicious advertisements automatically deliver the ransomware when visited.
- Peer-to-Peer (P2P) Sharing – Torrent networks and file-sharing sites serve as distribution points for infected archives.
2. Execution & Deployment
Once delivered, Solara executes immediately or after a delay to avoid sandbox detection. Common behaviors include:
- Disabling Security Tools – Attempts to terminate antivirus processes using built-in Windows commands and PowerShell scripts.
- Copying to Multiple Directories – Drops copies of its executable in common startup and temp folders for persistence.
- Trigger-Based Execution – Activates when certain “anti-crack” triggers or HWID (Hardware ID) checks are met, as described in the ransom note.
3. Encryption Process
- File Selection – Scans all available drives for target file extensions, skipping system-critical files.
- Chaos-Based Algorithm – Uses AES/RSA hybrid encryption similar to older Chaos variants.
- File Renaming – Appends .solara to encrypted files (e.g., image.png → image.png.solara).
- Ransom Note Deployment – Creates read_it.txt in multiple folders, including the desktop, with payment instructions.
4. Defense Evasion
- Shadow Copy Deletion – Runs vssadmin delete shadows /all /quiet to prevent file restoration via previous versions.
- Startup Persistence – Creates registry entries under HKCU\Software\Microsoft\Windows\CurrentVersion\Run.
- No Direct C2 Communication – In many observed samples, no live command-and-control server is contacted; the payload is self-contained, indicating offline operation.
5. Tools and Utilities Used
- Built-in Windows Commands (vssadmin, wmic, taskkill) – Used for disabling recovery points and killing processes.
- PowerShell Scripts – Automates payload execution and obfuscation.
- Packers/Crypters – Custom or off-the-shelf obfuscation tools to avoid detection by antivirus software.
- Fake Installers – Modified software setup files to deliver the malicious payload.
