A Packet containing a long string of NOP’s followed by a command is usually indicative of what?

A.
A syn scan

B.
A half-port scan

C.
A buffer overflow

D.

Explanation:
Reference “This paper is for those who want a practical approach to writing buffer
overflow exploits. As the title says, this text will teach you how to write these exploits
in Perl.

…..
There are reasons why we construct the buffer this way. First we have a lot of
NOPs, then the shellcode (which in this example will execute /bin/sh), and at last
the ESP + offset values.” http://hackersplayground.org/papers/perl-buffer.txt
