It handles the plumbing — spawning the target, talking to it over a socket, packing addresses into the right byte order, parsing leaked pointers — so you can spend your brain on the actual bug. <code>checksec</code>, which ships alongside it, is the thirty-second triage you run <em>first</em> on every binary to know what you&rsquo;re up against.</p>
