Multi AV Scanner detection for submitted file
Sample reads /proc/mounts (often used for finding a writable filesystem)
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
Writes identical ELF files to multiple locations
