How To Remove Yanluowang Ransomware (Malware Removal Guide)

  Category:  RANSOMWARE | 31st March 2026 | Author:  CSI'S TEAM

Yanluowang Ransomware Is A Relatively New But Highly Disruptive Cyber Threat That Emerged In 2021, Targeting Organizations Across Industries Such As Finance, Manufacturing, IT Services, And Engineering. It Operates As A Ransomware-as-a-Service (RaaS), Meaning Affiliates Rent The Malware To Conduct Attacks, Making It Harder To Trace And Dismantle. Recent Prosecutions, Including The Sentencing Of Russian National Aleksei Volkov To Nearly Seven Years In Prison, Highlight The Global Scale And Seriousness Of This Threat.

Origins And Development

• First Identified: August–October 2021 By Symantec’s Threat Hunter Team.

• Aliases: Sometimes Referred To As Dryxiphia.

• Connections: Shares Tactics, Techniques, And Procedures (TTPs) With Other Ransomware Families Like Thieflock And Fivehands, Suggesting Overlapping Affiliates Or Code Reuse.

Attack Methodology

• Initial Access Brokers (IABs): Criminals Like Aleksei Volkov Infiltrated Corporate Networks And Sold Access To Yanluowang Operators.

• Encryption & Extortion: Once Inside, Affiliates Encrypted Victim Data And Demanded Ransoms Ranging From $300,000 To $15 Million.

• Double Extortion: Victims Faced Threats Of Both Data Encryption And Public Leaks If They Refused To Pay.

• Targeted Sectors: Financial Institutions, Engineering Firms, IT Consultancies, And Manufacturing Companies Were Frequent Victims.

Impact

• Financial Losses: Attacks Caused over $9 Million In Actual Damages And Attempted To Extort $24 Million In Ransom Payments.

• Operational Disruption: Victims Often Faced Downtime, Reputational Damage, And Regulatory Scrutiny.

• Global Reach: Though First Detected In The U.S., Yanluowang Has Impacted Organizations Worldwide.

Law Enforcement Response

• Arrest & Sentencing: Aleksei Volkov, A Russian National, Was Arrested In Italy In 2024 And Extradited To The U.S. He Was Sentenced In March 2026 To 81 Months (6.75 Years) In Prison For His Role As An IAB.

• Significance: His Conviction Underscores International Cooperation In Combating Ransomware And Highlights The Importance Of Targeting Not Just Operators But Also Facilitators Like Access Brokers.

Defensive Measures

Organizations Can Reduce Risk By:

• Implementing Zero Trust Security Models To Limit Lateral Movement.

• Regular Patching And Vulnerability Management To Prevent Exploitation.

• Employee Training To Recognize Phishing Attempts, A Common Entry Point.

• Backup Strategies With Offline Storage To Mitigate Encryption Threats.

• Threat Intelligence Monitoring To Detect Early Indicators Of Compromise.

Conclusion

Yanluowang Ransomware Exemplifies The Evolution Of Cybercrime Into A Service-based Model, Enabling Widespread Attacks By Lowering The Barrier To Entry For Affiliates. Its Reliance On Initial Access Brokers And Double Extortion Tactics Makes It Particularly Dangerous. While Law Enforcement Victories Like Volkov’s Sentencing Are Encouraging, Organizations Must Remain Vigilant, As Ransomware Groups Continually Adapt Their Strategies. The Fight Against Yanluowang And Similar Threats Requires A Combination Of technical Defenses, Legal Action, And International Collaboration.

VPN - How To Use IT

1. Choose A Trusted VPN Provider

• Why It Matters: Not All VPNs Offer Malware Protection.

• What To Look For: Providers With built-in Malware/ad/tracker Blockers (e.g., NordVPN’s Threat Protection, ProtonVPN’s NetShield).

• Nord VPN
• Hide.me VPN

2. Enable Kill Switch

• Purpose: Prevents Data Leaks If Your VPN Connection Drops.

• Benefit: Ensures Your Real IP And Browsing Activity Aren’t Exposed To Malware-distributing Websites.

3. Use VPN With DNS Leak Protection

• Why It Matters: DNS Leaks Can Expose Your Online Activity To Attackers.

• Solution: Enable DNS Leak Protection In Your VPN Settings Or Use A Secure DNS Like Cloudflare (1.1.1.1).

4. Avoid Free VPNs

• Risk: Free VPNs Often Contain Malware, Sell User Data, Or Lack Security Features.

• Better Option: Use Reputable Paid VPNs That Offer security Audits And Transparent Privacy Policies.

5. Use VPN With Anti-Phishing Tools

• Some VPNs Block Known Phishing And Malicious Sites.

• Example: Surfshark’s CleanWeb, CyberGhost’s Content Blocker.

6. Keep Your VPN App Updated

• Reason: Security Patches Fix Known Vulnerabilities.

• Tip: Enable Auto-updates Or Check For Updates Weekly.

. Use VPN On All Devices

• Scope: Malware Can Enter Through Phones, Tablets, Or IoT Devices.

• Solution: Install VPN Apps On Every Internet-connected Device.

8. Don’t Rely On VPN Alone

• Fact: VPNs Do Not Remove Or Detect Malware On Your System.

• Complement It With:

  • Antivirus Software

  • Firewall

  • Browser Extensions For Script Blocking

9. Avoid Clicking Unknown Links While VPN Is On

• VPN Encrypts Traffic But Can’t Stop Malware From Executing If You Download Infected Files.

10. Use VPN With Split Tunneling Cautiously

• Split Tunneling Allows Certain Apps/sites To Bypass VPN.

• Tip: Never Exclude Browsers, Email Clients, Or Download Managers From VPN Tunneling.

Short Note - VPN Uses

A VPN (Virtual Private Network) Enhances Your Online Privacy By Encrypting Your Internet Traffic And Masking Your IP Address. It Protects Your Data On Public Wi-Fi, Hides Browsing Activity From Hackers And ISPs, And Helps Bypass Geo-restrictions. VPNs Also Add A Layer Of Defense Against Malware By Blocking Malicious Websites And Trackers When Using Advanced Features. However, A VPN Does Not Remove Existing Malware Or Act As Antivirus Software. For Full Protection, Combine VPN Use With Antivirus Tools, Regular Software Updates, And Cautious Browsing Habits. Always Choose A Reputable VPN Provider With Strong Security And Privacy Policies.
