Score:
100 / 100
Signature
Connects to many ports of the same IP (likely port scanning)

Drops invisible ELF files
Executes the "crontab" command typically for achieving persistence
Modifies the '.bashrc' or '.bash_profile' file typically for persisting actions
Multi AV Scanner detection for submitted file
Sample deletes itself
Sample reads /proc/mounts (often used for finding a writable filesystem)
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
Terminates several processes with shell command 'killall'
Writes identical ELF files to multiple locations
