Re: pentest physical security

Mervyn,

You are off point here with the topic, which is physical security
pentesting. So I will provide you some insight into the article you
suggested.

Using USB flash drives to circumvent logical security is a new twist to
an old game. The old game was to use a CD marked with something like
"confidential - companyname finances" loaded with Trojan software.
This attack vector worked all the time.

A better attack is sending someone a repackaged commercial piece of
software with a custom Trojan. This attack is targeted based on the
role of the person at the company. Examples include sending a finance
person a new update to Quickbooks or an engineer a copy of AutoCad.
This attack vector worked all the time.

Another twist that also works is sending a new piece of hardware (e.g.
switch, router, server, etc.) to a company that has been physical
modified to assist you gaining access to the network after it has been
installed.

These latter attacks cost money, but are used to today to gain access to
corporations.

Ok, now lets get back on point with physical security.

Posing as a cleaning person allows you to obtain unrestricted access
into some sensitive locations (e.g. CxO offices). The trash makes a
great place to hide disk duplication equipment, hardware keystroke
loggers and other equipment. The disk duplication equipment allows
you
to copy the laptop and desktop hard drives without stealing
them. The
keystroke loggers allow you to obtain passwords for encrypted
files and
other applications.

Posing as HVAC personnel also works.

The cleaning crews can expose MAJOR gaps in an organization security
posture as noted below:

I once provided a FREE physical security inspection and a
vulnerability
assessment to a Fortune 500 telecommunications firm (requirement for
Masters Degrees). Part of my assessment was to questioned the
cleaning
company that provided services to this telecommunications firm. The
cleaning company did verify anything about their workers and most
were
from Asia countries (mostly Korea and China). These workers had
unrestricted access into development areas for new products (e.g.
cellular, networking, etc.).

When I provided my final report to the company nothing changed. I
know
this because I worked at this company for a year after the report and
caught several cleaning people in restricted areas looking at project
information. When asked what they were doing they stated that
they did
not understand English and hurried away...............
