deadbeef?

Post by hgoel0974 » Tue Jan 29, 2013 1:59 am

I am looking at some exploit and in the debugger, I see lots of deadbeef, is that like null for the registers?

When there is a return from a syscall, 0xDEADBEEF are placed all over to avoid data leak.

Some memory managers write deadbeef arround memobjects to know if there is a leak.

at least i do that.. I'd say its actully pretty normal for a c++ dev
