Kubatanidza zvakare kunoita kuti zvikwanise kuita kuti basa rekutamisa mumaraibhurari risatarisike, izvo zvinoita kuti zviome kugadzira mashandisiro uchishandisa return-oriented programming (ROP) nzira. Paunenge uchishandisa iyo ROP tekinoroji, anorwisa haaedze kuisa kodhi yake mundangariro, asi anoshanda pane zvidimbu zvemichina mirairo yatovepo mumaraibhurari akaremerwa, ichipera nekuraira kudzoka kwekutonga (semutemo, aya ndiwo magumo emabasa eraibhurari) . Basa rekushandisa rinouya pasi pakuvaka ketani yemafoni kune akafanana mabhuroko ("magajeti") kuti uwane iyo inodiwa kushanda.
