Re: LAN pen test

Hi,

For an updated XP machine, whithout additional network
services or network applications, maybe you will need
a 0day exploit - an exploit for a vulnerability not
yet patched by the vendor. Sometimes, security
researches disclose 0day exploits for the public.
Recently, some exploits for Internet Explorer and MS
Office applications were disclosed before Microsoft
could patch the holes. If you were doing an internal
pen-test trying to own the network administrator
workstation, you could try to do a DNS poisoning or
just an arp poisoning attack (take a look on ettercap
and dsniff) to redirect the target for your web site,
exploiting an Internet Explorer flaw, for example.

But if you can´t find a known vulnerability for your
target, you can try by yourself discover a security
hole and write an exploit.

A suggestion: in the learning of the "pen-test art" is
better to first understand deeper the common kinds of
vulnerabilities and have the fundamentals, instead of
just run exploits downloaded from the web.

Best Regards,

Bruno Cesar Moreira de Souza
