Mozi IoT Botnet | Mozi IoT Botnet Description

  Category:  INFO | 8th July 2026 | Author:  CSI'S TEAM

Mozi Is An Advanced IoT Malware That Has Been Observed Spreading Across Internet-connected Devices Worldwide. Once A Device Is Infected, It Becomes Part Of A Large Peer-to-peer (P2P) Botnet That Attackers Can Exploit For Malicious Activities Such As Distributed Denial-of-service (DDoS) Attacks, Unauthorized Data Theft, And The Execution Of Additional Malicious Payloads.

Security Researchers Have Identified That Mozi Incorporates Techniques And Source Code Derived From Well-known IoT Malware Families, Including Gafgyt, Mirai, And IoT Reaper. The Malware Primarily Targets Embedded Linux-based Devices By Exploiting Exposed Telnet Services. Home Routers, Digital Video Recorders (DVRs), And Similar IoT Equipment Are Especially Vulnerable When They Are Running Outdated Firmware, Use Default Or Weak Telnet Credentials, Or Are Improperly Configured.

After Successfully Compromising A Device, Mozi Connects It To A Decentralized P2P Botnet Instead Of Relying On A Traditional Command-and-control Server. It Leverages A Distributed Hash Table (DHT) Protocol To Exchange Information And Coordinate With Other Infected Devices, Making The Botnet More Resilient And Difficult To Disrupt.

Mozi Infection Process

The Mozi Malware Propagates Through A Sequence Of Automated Steps That Enable It To Recruit Vulnerable IoT Devices Into Its Peer-to-peer Botnet.

1. Preparation Of Malware Distribution: An Already Infected Device (bot Node) Initiates A Temporary HTTP Service On A Randomly Selected Local Port To Host The Malware Payload. Alternatively, It May Receive The Malware Download URL Through A Configuration File Distributed By The Botnet Operator.
2. Compromise Of Target Devices: The Infected Bot Scans For Vulnerable IoT Devices, Particularly Those Exposing Telnet Services. It Attempts To Gain Access Using Weak Or Default Login Credentials. In Some Cases, Mozi Exploits Known Software Vulnerabilities To Obtain Unauthorized Access Instead Of Relying On Password Attacks.
3. Payload Delivery: Once Access Is Obtained, The Bot Uploads A Lightweight Downloader Script To The Target Device, Often Using Simple Shell Commands Such As echo. The Downloader Is Then Executed, Retrieving The Main Mozi Malware Binary From The Download Location Provided By The Infected Bot Node.
4. Execution And Botnet Enrollment: After The Malware Binary (commonly Named Mozi.m Or Mozi.a) Is Executed, The Compromised Device Joins The Mozi Peer-to-peer (P2P) Network. It Becomes A New Bot Node Capable Of Communicating With Other Infected Devices Through The Distributed Hash Table (DHT) Protocol.
5. Propagation: As A Newly Enrolled Bot, The Infected Device Begins Scanning For Additional Vulnerable IoT Systems, Repeating The Infection Cycle And Expanding The Botnet Without Relying On A Centralized Command-and-control Server.

The Vulnerabilities Exploited By Mozi Botnet Are Shown As:

Countermeasures And Best Practices For Prevention:

Users And Administrators Are Advised To Take The Following Preventive Measures To Protect Their Devices:

• Users Are Advised To Update Their Devices With Patches As & When Released By Respective OEM Of Devices
• If Devices Found Infected, It Is Recommended To Reset Device Firmware Or Restore It From Trusted Backup.
• Monitor Or Block UDP Traffic From The Device To Bit Torrent DHT Bootstrap Nodes
• Block Outgoing TCP Traffic With Destination Ports 22, 23, 2323, 80, 81, 5555, 7574, 8080, 8443, 37215, 49152, And 52869, If Not In Use.

Mozi IoT Botnet

The Mozi IoT Botnet Is A Decentralized Network Of Compromised Internet Of Things (IoT) Devices Controlled By The Mozi Malware. First Identified In 2019, Mozi Primarily Targets Embedded Linux-based Devices Such As Home Routers, Digital Video Recorders (DVRs), Network Video Recorders (NVRs), And Other Smart Devices That Are Exposed To The Internet. It Spreads By Exploiting Weak Or Default Telnet Credentials And Known Software Vulnerabilities In Unpatched IoT Devices.

Unlike Traditional Botnets That Rely On Centralized Command-and-control (C2) Servers, Mozi Uses A peer-to-peer (P2P) Communication Architecture Based On The Distributed Hash Table (DHT) Protocol. This Decentralized Design Enables Infected Devices To Communicate Directly With One Another, Making The Botnet More Resilient To Disruption And More Difficult For Security Researchers And Law Enforcement To Dismantle.

Once A Device Is Compromised, It Becomes A Bot Node Within The Mozi Network. The Infected Device Can Receive Commands, Participate In Malware Distribution, And Assist In Infecting Additional Vulnerable IoT Devices. The Botnet Has Been Associated With Several Malicious Activities, Including Distributed Denial-of-service (DDoS) Attacks, Payload Delivery, Unauthorized Execution Of Commands, And Other Cyberattacks Orchestrated By The Botnet Operators.

Mozi Has Become One Of The Most Significant IoT Botnets Due To Its Rapid Propagation, Decentralized Infrastructure, And Ability To Compromise A Wide Range Of Internet-connected Devices. Protecting Against Mozi Requires Disabling Unnecessary Remote Services Such As Telnet, Using Strong And Unique Passwords, Regularly Updating Device Firmware, And Applying Security Patches To Eliminate Known Vulnerabilities.

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.
