Signatures

Antivirus / Scanner detection for submitted sample
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Yara detected Mirai
Connects to many ports of the same IP (likely port scanning)
Executes the "crontab" command typically for achieving persistence
Creates hidden files and/or directories
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 "chmod" command used to modify permissions
Found strings indicative of a multi-platform dropper
Sample contains strings indicative of BusyBox which embeds multiple Unix commands in a single executable
Sample has stripped symbol table
Sleeps for long times indicative of sandbox evasion
Tries to connect to HTTP servers, but all servers are down (expired dropper behavior)
Yara signature match

NameDescriptionAttributionBlogpost URLsLink
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
