Yara detected Mirai
Multi AV Scanner detection for submitted file
Uses known network protocols on non-standard ports
Deletes log files
Sample has stripped symbol table
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
Executes the "systemctl" command used for controlling the systemd system and service manager
Tries to connect to HTTP servers, but all servers are down (expired dropper behavior)
Detected TCP or UDP traffic on non-standard ports
Sample listens on a socket
Sample tries to kill a process (SIGKILL)
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. |
