Selvom ping er suid root så har alle brugere jo ikke
skrive adgang til at overskrive ping. Så kun hvis en
virus kører som root kan den pille ved ping, men så
er det langt lettere måder at inficere computeren på.
Fx. ved at introducere en backdoor i en standard service,
pille i kernel imaget, eller rode i /prov/kmem.
