Sample reads /proc/mounts (often used for finding a writable filesystem)
Enumerates processes within the "proc" file system
Executes the "rm" command used to delete files or directories
Found strings indicative of a multi-platform dropper
Sample has stripped symbol table
Sample listens on a socket
Sample tries to kill a process (SIGKILL)
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)

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
