How to Remove SpiderPery Ransomware and Decrypt (.SpiderPery) Files?

Overview: What is SpiderPery Ransomware?

First identified via submissions on VirusTotal, SpiderPery ransomware is a crypto-malware variant that encrypts user and system files, appending them with a custom unique identifier followed by the .SpiderPery extension. Victims are left with a ransom note titled ReadMe.txt, instructing them to contact the attackers via Telegram (@spiderPrey). The ransomware is designed to compromise both desktop systems and enterprise server environments, including Windows Server and VMware’s ESXi hypervisors.

Observed Tactics, Techniques, and Procedures (TTPs)

Initial Access

• Phishing Emails: With malicious attachments or OneNote documents to deliver the payload.
  
• Exploiting Internet-Facing Apps: Vulnerabilities in VPN, RDP, Citrix, and web servers are common vectors.
  

Credential Harvesting and Persistence

• Use of Mimikatz, LaZagne, and DCSync attacks to harvest credentials.
  
• MFA bypass using adversary-in-the-middle (AiTM) phishing kits such as Evilginx.
  
• Deployment of remote administration tools like AnyDesk and ScreenConnect.
  

Lateral Movement and Privilege Escalation

• Impacket toolkit, PsExec, and exploitation of Active Directory environments.
  
• Lateral movement within both cloud and on-prem environments using harvested credentials and open ports.
  

Encryption and Ransom Demand

• Files are encrypted using AES-256 or RSA-based hybrid cryptographic methods.
  
• Victims receive a ReadMe.txt file threatening permanent data loss unless payment is made—typically in cryptocurrency.

The ransom note contains the following message:

All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC.
Telagram ID: @spiderPrey
Write this ID in the title of your message

ID : –

SpiderPery Ransomware Targets: Windows Servers and ESXi

On Windows Servers

• Critical databases and operational files are encrypted.
  
• System restore points and Volume Shadow Copies are deleted to prevent recovery.
  

On ESXi Systems

• Virtual machines are locked using SSH-based attacks or by exploiting outdated ESXi builds.
  
• Entire virtualized infrastructures may become inaccessible within minutes of deployment.

Indicators of Compromise (IOCs)

File and Extension Patterns

• File Renaming: filename.jpg becomes filename.jpg[g7jjo9].SpiderPery
  
• Ransom Note: ReadMe.txt contains ID and Telegram contact
  

Malicious Network Activity

• Contact with C2 infrastructure on obfuscated IPs (e.g., 144.76.136.153)
  
• Short-lived phishing domains mimicking Okta, SSO, or VPN portals
  

System and Network Anomalies

• Sudden spikes in CPU/disk usage during encryption
  
• Unusual outbound traffic during data exfiltration stages

Unified Protection Strategy Against SpiderPery

To prevent future attacks, implement a layered security approach:

1. Patch Regularly: Prioritize ESXi and Windows vulnerabilities.
   
2. Zero Trust Access: Use MFA and limit administrative privileges.
   
3. Network Segmentation: Isolate critical assets with VLANs and firewalls.
   
4. Backup Strategy: Employ 3-2-1: three backups, two media types, one off-site.
   
5. Advanced EDR: Deploy endpoint detection and response tools.
   
6. Phishing Training: Regularly train staff to recognize attack vectors.
   
7. Incident Readiness: Maintain and test incident response playbooks.
