Multi AV Scanner detection for submitted file
Sample deletes itself
Sample reads /proc/mounts (often used for finding a writable filesystem)
Sample tries to kill a massive number of system processes
Sample tries to kill multiple processes (SIGKILL)
Sample tries to persist itself using /etc/profile
Sample tries to persist itself using cron
Sample tries to persist itself using System V runlevels
Sample tries to set files in /etc globally writable
Suricata IDS alerts for network traffic
