How I “Pwn” Your Network: A Chat with a Social Engineer and

Facility Breach Expert

“It’s increasingly harder to break in on the external perimeter, adaptation occurs towards our weakest link, the human element.”

- Dave Kennedy (ReL1K), Developer of the Social Engineering Toolkit (SET)

• Why would I fight your: – Security Information Event Management (SIEM)

– Anti-Virus

– HIPS/NIPS/IPS/IDS

– Web Application Firewalls

– Secure Coding Practices

– Patch Management

• Why would I fight everything you’ve built into your entire security program….when I can just walk in and take your data?

We exploit the gap between:

Corporate Security

Information Security

Network

Web Applications

Wireless Facility

Users

• Google-Fu + Bing-Fu => FTW!

– Facility layout and surroundings

– Job openings

– Telco providers

• Corporate website - Investor relations,

corporate officers, contact info, etc.

• Social networking sites (LinkedIn,

Facebook, Twitter, etc.)

Social Engineer’s Toolkit (SET)

• Is a toolkit “specifically designed to perform advanced attacks against the human element” that is built on top of the MSF. – Developed by David Kennedy (ReL1K)

• Will conduct the following attacks: – Spear-Phishing – Spoof or utilize already established email

addresses to do spear-phishing attacks with file format attack vectors.

– Web Attacks – Multiple attack vectors including Java applet, client-side exploits, tabnabbing, man left in the middle, and the credential harvester.

– Infectious Media Generator – Creates a CD/DVD which allows you to deploy MSF payloads in a simple autorun.

– Arduino / Teensy USB HID Attack Vector – Multiple payload selection for the USB keyboard HID attacks.

– And so much more!

Breaking In: For us, it’s all about

style…

• Numerous ways to accomplish my goals:

– Technical and Non-Technical methods

– Point and Area Targets

• Point Targets – Targeting an individual

– This means YOU!

– Phone, email, social networking, face-to-face

• Area Targets – Targeting a site

– Tailgating, baiting, “Red Team” exercise, lockpicking,

dumpster diving, etc.

Point Targets

Phone Domination

• Let’s have a listen…

DEMO: Spoof Card

• Social networking is my dream and your nightmare.

• TMI = Too Much Information about you and your company.

• Why do IT guys like to just “tell it all” on these sites?

Face to Face

• Sometimes this is actually easier for a social engineer.

– Easier to gauge reaction.

– Harder to dismiss someone in front of you.

• Relies completely on the skill of the social engineer

– Must react to the situation immediately

– Know when to push and when to retreat

Face to Face

• It’s not as easy as you think to avoid…

• Let’s take at what happens when you are successful….

Area Targets

• No lock is perfect

• Various types

– Pin Tumbler locks

– Wafer locks

– Cipher locks

– Code and card

operated locks

– Padlocks

• Only a delaying

mechanism

DEMO: Lock Picking

Tailgating

• A frequently used attack vector

• Why?

– It works and requires almost no skill

– (I bet you’ve used it before yourself!)

DEMO: The PwnPlug

Programmable HID USB

Keystroke Dongle • USB device that emulates a USB keyboard and drivers and

will execute commands (i.e. install malware, reverse shell,

shutdown A/V, etc.)

• Why do I use it?

– Types faster than I can, without errors

– Works even if autorun is disabled

– Draws less attention

– Can be set to go off on a timer…e.g. when my target is logged on

**Important Safety Tip**

An individual information gathering technique

or attack vector is rarely successful. It is the

combination of these techniques that make

this a credible threat to your infrastructure.

Defeating the Social Engineer

We’ll make this real simple…

1. What I love to see and hear

2. What I hate to see and hear

What I LOVE to see and hear

• “You won’t get in….according to the audit

committee…we’re compliant.”

• A contract security guard who is busy with

non-security tasks

• “The Beige Plastic Gambit”

• Nice employees

• “The Cameraman of Security Theater”

What I HATE to see and hear

• A nosy workforce with regular security

awareness training

• Rapid and effective incident response

• Patch management that patches

• Physical Security Information Management

(PSIM)

• Visitor management

• Turnstiles & Anti-Passback devices

• Tech controls that work, but aren’t sexy
