First Actions After a Pear Attack
- Disconnect compromised systems immediately to inhibit further propagation.
- Preserve the ransom note, encrypted data, logs, and forensic captures in unaltered form.
- Do not reboot or reformat—these actions can eliminate recovery options.
- Engage expert responders without delay to maximize recovery chances.
Free Recovery Approaches
1. Backup Restoration
If secure backups exist, restoring from these offers the safest route to full operational recovery.
How it works?
Offline, air-gapped, or cloud-based backups should be verified using integrity checks such as SHA-256 before restoration. Administrators can wipe the infected system and reinstall using the latest clean image.
Challenges:
Pear is known to delete or corrupt backups. Partial encryption of backup folders or slow responses by internal SOCs can render this option risky if not detected early.
Tip:
Use immutable backups stored in write-once-read-many (WORM) systems, and regularly test restore points to confirm validity.
2. Shadow Volume Copy Rollback
In some scenarios, volume shadow copies may survive the attack—especially if protection tools disrupted Pear’s post-exfiltration cleanup scripts.
How it works?
Using Windows’ built-in tools (vssadmin list shadows), administrators can check for remaining snapshots. Tools like Shadow Explorer or Recuva can also help access residual data.
Limitations:
Pear typically executes a full vssadmin delete shadows /all /quiet command before initiating ransom activity. Therefore, success is rare.
3. File Recovery Utilities
Low-level file recovery tools like PhotoRec, R-Studio, or EaseUS may recover overwritten or deleted files.
Limitations:
Recovery depends on whether the disk blocks have been overwritten or not. This method should only be attempted in forensics labs or under expert supervision.
Paid Recovery Options
1. Paying the Ransom (Not Recommended)
Pear demands vary widely—from $150,000 for smaller organizations to $500,000+ for enterprises.
How it works?
Payment is made in cryptocurrency (usually BTC) to the attacker’s wallet. In return, a decryptor tied to your ransom note’s unique victim ID is sent via TOR.
Risks:
Attackers may not honor the payment. Decryptors provided could be faulty, delayed, or contain hidden backdoors. Payment also funds criminal activities and may violate compliance or government regulations.
2. Using Third-Party Negotiation Firms
Specialized ransomware negotiation firms can engage Pear on your behalf.
What they do?
They reduce the ransom, validate the attacker’s decryptor with test files, and ensure the transaction follows compliance protocols.
Costs:
Fees can range from 10–30% of the original ransom amount, but they often achieve faster resolution and legal audit coverage.
Our Proprietary Pear Ransomware Decryptor
After extensive reverse engineering, our cybersecurity team has developed a dedicated decryptor for Pear ransomware.
How the Tool Works?
- Victim ID-Based Matching
The tool reads the pear_restore.txt file to extract the unique login ID issued by Pear. This maps your encrypted files to a secure decryption key. - Cloud-Powered Decryption
The tool connects to our secure cloud processing node. All files are scanned, decrypted in a sandbox, and verified with blockchain-based hash validation before being returned. - Offline Decryption Option
For sensitive sectors (government, defense, healthcare), an offline version is provided that uses locally generated keys based on timestamp, file entropy, and ransom note seed data. - Zero-Impact Read Mode
All encrypted files are initially scanned in read-only mode to prevent modification or corruption.

Offline vs. Online Mode Explained
Offline Mode
Best for restricted or air-gapped systems. Files are transferred via removable storage and decrypted on an isolated, hardened system.
Online Mode
Faster and ideal for enterprises. Files are securely uploaded, decrypted in a private cloud node, and returned with proof-of-integrity.
Our decryptor supports both approaches—giving organizations the flexibility to meet their operational and security requirements.
What Is Known About Pear Ransomware?
Pear operates with a .pear file extension and does not encrypt files in traditional fashion—instead, it steals data (double-extortion style) and holds it for ransom. It first emerged publicly in early August 2025, targeting 18 organizations. The average interval between a breach and public disclosure is 28.4 days.

Timeline of Incidents
Negotiation Behavior and Blackmail Tactics
Pear employs high-pressure negotiation tactics. They exact leverage by posting exfiltrated data to a leak site and refuse compromise—even when presented with partial payments. A practice noted in the ThinkBig incident involved exposing sensitive personal and financial data, possibly undermining negotiations.
Technical Indicators Available
Current publicly identified IoCs include:
- Email: pear@onionmail.org
- TOX hash: 457BB4E5DF0E650509322CA894758D925A568828090A3449D5AEEED30E9B8E18DDDFF71909ED
Tools and Techniques Used by Pear Ransomware
Pear ransomware follows a highly targeted, stealth-driven approach to enterprise compromise. Drawing parallels from threats like Snatch and BlackByte, Pear’s campaigns reveal a calculated abuse of legitimate tools, custom scripts, and encryption libraries to silently extract and ransom sensitive data.
Initial Access
Pear typically gains entry via vulnerable edge devices, brute-forced credentials, and remote access services lacking MFA. Phishing campaigns are also used to harvest initial login data.
- Brute Force & Credential Stuffing
Exploits weak VPN or RDP credentials to access networks without raising alarms. Cisco ASA, Fortinet, and SonicWall appliances with known flaws are favorite targets. - Exploited Vulnerabilities
Vulnerabilities like CVE‑2022‑40684 (Fortinet) and CVE‑2020‑3259 (Cisco ASA) are leveraged for firewall or VPN bypass.
Lateral Movement and Reconnaissance
Once inside, Pear operators use a series of well-known admin and network scanning tools to identify key assets.
- Advanced IP Scanner & SoftPerfect Scanner
Used to identify live hosts, open ports, and accessible shares across LAN/WAN environments. - LaZagne and Mimikatz
Deployed for credential dumping from memory, browser stores, and Active Directory caches. - AdFind and BloodHound
These tools are used to map domain structure and enumerate privilege paths for escalation.
Defense Evasion
Pear uses both Bring Your Own Vulnerable Driver (BYOVD) techniques and known rootkit utilities to stay undetected.
- PowerTool & Zemana AntiLogger
These are used to disable EDR/AV engines or sidestep detection. - ProcessHacker and PCHunter64
Allow manipulation of Windows processes, thread killing, and kernel-level inspection.
Data Exfiltration
Before any ransom is issued, Pear exfiltrates sensitive business data to cloud or third-party storage.
- FileZilla, RClone, and WinSCP
Frequently used to move data silently to attacker-controlled servers. - Ngrok, Mega, and AnyDesk
Provide command and control channels, persistence, and encrypted tunnels for data transfer.
Encryption Method
Pear uses a dual-stage encryption process similar to BlackByte:
- ChaCha20 for file encryption, selected for its speed.
- RSA-4096 to encrypt the session key, securing the ChaCha keys.
Before encrypting, all Volume Shadow Copies are deleted using:
vssadmin delete shadows /all /quiet
The ransomware may also execute PowerShell scripts to disable backup services and enforce full encryption.
