About jgamblin/Mirai-Source-Code

A GitHub repository hosting the leaked source code of the Mirai botnet, originally used to infect IoT devices and launch large-scale DDoS attacks. The code is provided strictly for cybersecurity research, reverse engineering, malware analysis, and detection (IoC) development. It includes the bot malware for IoT devices, command-and-control (CnC) server, a loader that infects vulnerable devices via telnet brute-force, and supporting scripts. The repository offers cross-compilation support for architectures like ARM and MIPS and requires a Linux host with specific build tools. A critical disclaimer warns against using the code on real devices or networks, emphasizing legal and policy violations. The zip file is flagged by some antivirus programs as malware, so caution is advised.

FAQ

What is Mirai?

Mirai is a malware botnet that infects Internet of Things (IoT) devices using default or weak login credentials. Once infected, these devices are controlled by a command-and-control server and can be used to launch DDoS attacks.

What are the requirements to build and run this code?

You need a Linux host with gcc, golang, electric-fence, mysql-server, mysql-client, build-essential, and crossbuild-essential-armel installed. Detailed instructions are in the README.

Is it legal to use this code?

No, using this code to attack or scan real devices or networks is illegal and violates GitHub policy. The code is provided strictly for research and detection development in isolated lab environments.
