Malicious sample detected (through community Yara rule)

Antivirus / Scanner detection for submitted sample

Yara detected Mirai

Detected Mirai

Multi AV Scanner detection for submitted file

Snort IDS alert for network traffic

Connects to many ports of the same IP (likely port scanning)

Yara signature match

Sample has stripped symbol table

Uses the "uname" system call to query kernel version information (possible evasion)

Found strings indicative of a multi-platform dropper

Enumerates processes within the "proc" file system

Tries to connect to HTTP servers, but all servers are down (expired dropper behavior)

Detected TCP or UDP traffic on non-standard ports

Sample contains strings indicative of BusyBox which embeds multiple Unix commands in a single executable

Classification

Analysis Advice

Static ELF header machine description suggests that the sample might not execute correctly on this machine.

All HTTP servers contacted by the sample do not answer. The sample is likely an old dropper which does no longer work.

Static ELF header machine description suggests that the sample might only run correctly on MIPS or ARM architectures.

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.
