Yara detected Mirai

Multi AV Scanner detection for submitted file

Sample deletes itself

Sample is packed with UPX

Deletes security-related log files

Opens /proc/net/* files useful for finding connected devices and routers

Executes the "kill" or "pkill" command typically used to terminate processes

Sample contains only a LOAD segment without any section mappings

Reads CPU information from /sys indicative of miner or evasive malware

Yara signature match

Deletes log files

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

Enumerates processes within the "proc" file system

Executes commands using a shell command-line interpreter

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

Executes the "rm" command used to delete files or directories

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.
