Signatures

Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Yara detected Mirai
Uses IRC for communication with a C&C
Uses known network protocols on non-standard ports
Detected TCP or UDP traffic on non-standard ports
Enumerates processes within the "proc" file system
Executes commands using a shell command-line interpreter
Executes the "kill" or "pkill" command typically used to terminate processes
Reads CPU information from /sys indicative of miner or evasive malware
Sample and/or dropped files contains symbols with suspicious names
Sample contains strings indicative of BusyBox which embeds multiple Unix commands in a single executable
Sample contains strings indicative of password brute-forcing capabilities
Sample contains strings that are user agent strings indicative of HTTP manipulation
Tries to connect to HTTP servers, but all servers are down (expired dropper behavior)
Uses the "uname" system call to query kernel version information (possible evasion)
Yara signature match

Mirai Mirai is one of the first significant botnets targeting exposed networking devices running Linux. Found in August 2016 by MalwareMustDie, its name means "future" in Japanese. Nowadays it targets a wide range of networked embedded devices such as IP cameras, home routers (many vendors involved), and other IoT devices. Since the source code was published on "Hack Forums" many variants of the Mirai family appeared, infecting mostly home networks all around the world.
