Question

Ok so I’ve recently started doing some reverse engineering, and I keep coming across a term (I think) I have no idea what it means? A badboy?

Could anyone explain?

Maybe this is the answer:

Search for "badboy".

There are three types of breakpoints available to a reverse engineer:
hardware, memory, and INT 3h breakpoints. Breakpoints are essential to
a reverse engineer, and without them, live analysis of a module does
him or her little good. Breakpoints allow for the stopping of
execution of a program at any point where one is placed. By utilizing
this, reverse engineers can put breakpoints in areas like Windows
APIs, and can very easily find where a badboy message (a messagebox
saying you entered a bad serial, for example) is coming from. In fact,
this is probably the most utilized technique in cracking, the only
competition would be a referenced text string search. This is why
breakpoint checks are done over important APIs like MessageBox,
VirtualAlloc, CreateDialog, and others that play an important role in
the protecting user information process. The first example will cover
the most common type of breakpoint which utilizes the INT 3h
instruction.
