Signatures

Multi AV Scanner detection for submitted file
Yara detected Mirai
Connects to many ports of the same IP (likely port scanning)
Sample deletes itself
Sample is packed with UPX
Detected TCP or UDP traffic on non-standard ports
ELF contains segments with high entropy indicating compressed/encrypted content
Sample contains only a LOAD segment without any section mappings
Sample listens on a socket
Uses the "uname" system call to query kernel version information (possible evasion)

MiraiMirai 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.No Attributionhttps://malpedia.caad.fkie.fraunhofer.de/details/elf.mirai
