Loading malware…
Mirai is a self-propagating IoT botnet malware targeting embedded Linux devices, notably IP cameras, DVRs, home routers, VoIP devices, and other poorly secured network-connected equipment. Created by Paras Jha, Josiah White, and Dalton Norman, it initially supported attacks against gaming services before becoming responsible for major internet-scale DDoS events in 2016, including attacks affecting OVH, KrebsOnSecurity, and Dyn DNS infrastructure. Its source code was publicly released in 2016, enabling extensive reuse in later botnets and variants.
Classic Mirai scans pseudorandom internet addresses for exposed Telnet services and attempts authentication using hard-coded default and common credentials. Upon successful access, it reports the victim and credentials to loader infrastructure, which determines the device architecture and installs an appropriate payload. Mirai infections are generally non-persistent and can often be removed by rebooting a device, although vulnerable devices may be reinfected. It impedes competing malware and analysis by killing processes, removing its executable after launch, and randomizing its process name.
Mirai-controlled devices receive commands from command-and-control infrastructure to conduct high-volume DDoS floods. Variants and descendants have expanded propagation beyond Telnet credential attacks to exploit vulnerabilities in routers, IoT products, and internet-facing application frameworks, including Log4Shell and Spring4Shell. Mirai-derived malware has been observed across a broad range of embedded Linux CPU architectures and continues to be used by financially motivated botnet operators and, in some reported cases, repurposed by state-linked actors.

24 distinct techniques documented for this family, organized by ATT&CK tactic.
After the first login into the new victim device, it sent its IP and working credentials to the report/loader server.
The server then executes the attacker’s shell command ( id , or wget , or anything ) with full Node.js privileges.
Observed commands include “/bin/sh -c ... cd /tmp; wget ... | sh”, “whoami”, “id”, “uname”, “ifconfig”, and “ls /tmp/.”
After the first login into the new victim device, it sent its IP and working credentials to the report/loader server.
To impede analysis, Mirai samples store those credentials in an encoded form and decode them at runtime using a simple XOR with a constant.
When successfully infected, Mirai obfuscated its presence by deleting the malware binaries and randomizing the name of the running process.
