Never run this on a real device or public network.\r\n🔧 1. Prerequisites\r\nInstall on a Linux host:\r\nhttps://github.com/jgamblin/Mirai-Source-Code\r\nPage 2 of 4\n\nsudo apt update\r\nsudo apt install gcc make build-essential git crossbuild-essential-armel -y\r\n🔨 2. Clone the Repository\r\ngit clone https://github.com/jgamblin/Mirai-Source-Code.git\r\ncd Mirai-Source-Code\r\n🔨 3. Build the Bot and CnC\r\nThis will:\r\nCross-compile the bot for different IoT architectures (MIPS, ARM, etc.)\r\nCompile the CnC server for your local machine\r\nYou can customize the build script and source code paths if needed.\r\n🧪 4. Setup a Test Lab (Recommended)\r\nCreate a virtual lab with:\r\n1 Ubuntu VM for CnC and loader\r\n1 or more OpenWRT/Linux VMs simulating IoT devices\r\nUse Host-Only or Internal Networking mode to keep the lab isolated.\r\n🕹 5. Running Components\r\nStart the CnC server (mirai/cnc/cnc)\r\nRun the loader to infect virtual IoT VMs\r\nObserve communication logs, infection, and payload delivery\r\n✅ Learning Use Cases\r\nYou can use this source code to:\r\nUnderstand how botnets spread through weak credentials\r\nReverse engineer malware behavior\r\nWrite intrusion detection rules (YARA, Snort, Suricata)\r\nDevelop antivirus and botnet defenses\r\nhttps://github.com/jgamblin/Mirai-Source-Code\r\nPage 3 of 4\n\nStudy CnC-to-bot protocol and build simulators\r\n❌ Do NOT Use For\r\nScanning or infecting real IoT devices\r\nDDoS attacks\r\nDeploying the bot to the public internet\r\nAny such use is illegal and against GitHub policy.\r\n📚 References\r\nOriginal Leak on Hackforums (2016)\r\nDDoS Analysis of Mirai by MalwareMustDie\r\nUS-CERT Alert TA16-288A\r\n👨‍💻 Credits\r\nOriginal Author: Anna-senpai - Original Mirai botnet source code leak (2016)\r\nNote: The original forum appears to be inactive as of now.\r\n🙏 Acknowledgments\r\nSpecial thanks to Pushpenderrathore for the improved README structure and comprehensive documentation that\r\nmakes this educational resource more accessible for cybersecurity research.\r\nSource: https://github.com/jgamblin/Mirai-Source-Code\r\nhttps://github.com/jgamblin/Mirai-Source-Code\r\nPage 4 of 4", "extraction_quality": 1, "language": "EN", "sources": [ "Malpedia" ], "references": [ "https://github.com/jgamblin/Mirai-Source-Code" ], "report_names": [ "Mirai-Source-Code" ], "threat_actors": [], "ts_created_at": 1775434132, "ts_updated_at": 1775791216, "ts_creation_date": 0, "ts_modification_date": 0, "files": { "pdf": "https://archive.orkl.eu/adce17622f249f3bddb82eb3c3c7811b8916bf5b.pdf", "text": "https://archive.orkl.eu/adce17622f249f3bddb82eb3c3c7811b8916bf5b.txt", "img": "https://archive.orkl.eu/adce17622f249f3bddb82eb3c3c7811b8916bf5b.jpg" } }
