Hack Like a Pro: How to Spear Phish with the Social Engineering Toolkit (SET) in BackTrack

Welcome back, my rookie hackers!

Many newbie hackers focus upon the technical aspects of hacking and fail to give enough attention to social engineering. In fact, I would say that technical hacks should ONLY be attempted if social engineering attacks fail. Why bother spending hours or days trying to hack a password if someone will simply give it to you?

Social engineering is the act of getting people to give you the information you seek, usually by gaining their trust. That trust may be gained by posing as someone in authority, a colleague, or just someone who needs help. Some of the best hackers in history, including Kevin Mitnick, have been great social engineers.

BackTrack has a tool to assist and automate social engineering attacks called SET, or the Social Engineering Toolkit. SET was developed by David Kennedy and simplifies a number of social engineering attacks such as phishing, spear-phishing, malicious USBs, etc. Furthermore, it has been integrated with Metasploit so that we can use Metasploit exploits and payloads in our social engineering attacks.

The current version of the Social Engineering Toolkit includes the following types of attacks.

  • Spearphishing
  • Websites
  • Malicious USBs

So, let's fire up our BackTrack and explore the Social Engineering Toolkit!

Step 1: Open SET

To start using the Social Engineering Toolkit, go to BackTrack, then Exploitation Tools, then Social Engineering Tools, then Social Engineering Toolkit, and click on set.

Step 2: Pick Your Type

This should open the main menu for the Social Engineering Toolkit. Note that it offers:

  • Spear-Phishing Attacks
  • Website Attacks
  • Infectious Media Generator
  • Create a Payload and Listener
  • Mass Mailer Attack
  • Arduino-based Vector Attack
  • SMS Spoofing Attack
  • Wireless Access Point
  • And many others

In this tutorial, we'll be looking at creating a spear-phishing attack. For those of you not familiar with this terminology, a phishing attack is an email attack with a broad "net" in an attempt to try to pick up a few random victims. A spear-phishing attack is similar, except that it targets one or a few individuals. In other words, it's a targeted social engineering attack, hence the spear.

Step 3: Spear-Phish

Let's now select number 1 from the menu and begin our spear-phishing attack. When we do, we will be greeted with the screen below.

It explains what a spear-phishing attack is and asks us how we want to go about our attack. We can choose:

  1. Mass email attack
  2. FileFormat payload
  3. Social engineering template

Let's select a FileFormat attack. Type number 2 and press enter.

Step 4: Choose an Attack

After we select our FileFormat type attack, we will be asked what type of exploit we would like to use. Notice that the default is the PDF with the embedded .exe. In this hack, let's use the Microsoft Word RTF Fragments attack or MS10_087.

This will create a Word document that will overflow a buffer and enable us to put a listener or rootkit on the victim's machine. Type 4 and press enter.

Step 5: Choose a Payload

Now that we have decided what type of file we want to use in our attack, our next step is to decide what type of listener (aka rootkit, aka payload) we want to leave on the victim system. These may look familiar to those of you who have used Metasploit as these are Metasploit payloads.

Let's be ambitious and try to get the Metasploit meterpreter on that victim's machine. If we are successful, we will completely own that system!

Step 6: Create the File

After we type number 5 and press enter, we must choose what port we want to listen on (the default 443). SET then goes about creating our malicious file for us. It names that file template.rtf.

Step 7: Rename the File

If we want to trick the victim into opening the file, we should name it something that sounds enticing or familiar to the victim. Now this will differ depending upon the victim, but in our scenario we're trying to spear a manager at a large company, so let's call it SalesReport, something he or she might actually be expecting in their email.

Step 8: Create the Email

Now that we have created the malicious file, we now need to create the email. This is important. If we're to get the victim to open the file, the email must look legitimate. SET prompts us whether we want to use a pre-defined template or a one-time-use email template. Let's be creative and choose a one-time-use email.

SET then prompts us for the subject of the email. In this case, I used Sales Report. SET then asks us whether we want to send it in html or plain text. I chose html to make it look more inviting and legitimate. Finally, SET prompts us to write the body of the email and then type Control + C when we are finished. I wrote:

Dear BigShot:

Please find attached my quarterly sales report. If you have any questions, please feel free to ask.

Sincerely,

Your Minion

Of course, your email will differ depending upon who you're sending it to, but try to make it sound enticing and legitimate or they aren't likely to open the attached malicious file and our attack will fail.

When we're finished, SET will ask us whether we want to use a Gmail account or send it from our SMTP server. In most cases, we will want to use a Gmail account. Simply type in your address (you might want to create an anonymous email account for this purpose) and password, and SET will send the email you created with the malicious attachment from this Gmail account.

We will be using some of the other features of the Social Engineering Toolkit in future tutorials, so keep coming back!

Hey OTW was wondering if a anti virus programs like Avast and Norton would pick this up?

Archangelum:

Welcome to Null Byte!

In some cases, the AV software will pick this up and alert the user. In that case, we have to employ a different strategy or re-encode this exploit so that the AV doesn't see it.

OTW

OTW, I fell in love with all your tutorials. Can you make a video for all of it using screen capture software? That would be nice.

Salam OTW...

I am getting the error of Unable to clone this specific site , whenever i try to clone facebook or gmail,etc. plzzzz guide..

secondly,

the ip(got from if config) for various SET tools, is not accessible by any other remote pc as well as on my own pc..

Waiting for your help......

Sherdil:

if u cannot clone websites,there is some problem with ur internet connectivity...

by default your localhost(where the set saves the cloned page) cannot be accesed by remote machines,they can only be accesed by those machines which are inside your router.for making it publicly accesible you need to do port forward the inbound connections,

and for your second query... you can access the cloned page by typing your local ip in the browser..if it doesnt you need to start your apache service by these command <service apache2 start>

Good advice, Asif. Thanks

hello otw
my isp in india blocks port,so port forwarding doesnt work.is there any hack to bypass this..?

Dude i have why my email didnt receive any email? I put my dummy on the target email

I have no idea what you are asking. Want to try again?

Sorry for my bad english, but my dummy account didnt receive any mal file.

Hey dude gmail blocked my email how can i fixed that?

I would like to attach a keylogger as my payload into the email from the SET toolkit, and control it with an IRC client if thats at all possible, that way the target computer is not connected to my ip address, how would I go about doing this?

ld like to hear about this as well. Is it possible? And how would one accomplish this?

I exchanged messages with OTW at an earlier date and he informed me that a keylogger connected to an IRC can not be sent through the SET (toolkit) as it only supports attacks that are already coded into the toolkit, so in order to perform the attack through an IRC we would need to code the attack ourselves. (unless one is added to SET in the future, which is unlikely)

hi,could you help me? I try to use my gmail account, but gmail blocks all acount access outside a browser, thusly, not allowing SET to use it...is there any way to bypass this?if not? is there any other soluction? thanks anyway

I've been having the same problems lately. Looks like gmail no longer allows this.

No I always got the message saying they blocked the application then theres a section where I choose to allow unsafe whatever. Then I can use it through set easily. Its a matter of personal preferences in gmail.

nice tut, i wanted to ask is there a way to clone a specific email address,so the reciever will think its coming from a specific person?

my dummy gmail account cant get anytyp of mail and we hack facebook through but not in same LAN...and gmail is block this typ of mail and directly add into the spam ...any sollution ..?
