Phishing Frenzy: Installing the Monster
If you’ve been following along with us, you’ve noticed we recently released a new software tool for penetration testers called Phishing Frenzy (PF). PF is a feature rich ruby on rails application that helps manage your email phishing campaigns from creation, customization, to execution.
Introducing Phishing Frenzy
A couple weeks ago I presented at this years Derbycon on an email phishing platform that I have been working on. The web application is geared towards penetration testers who want to help streamline the creation and management of email phishing campaigns. The application is written in ruby on rails and is available for download on the Github repository: Phishing Frenzy.
For those of you who came out to my presentation, I appreciate you all getting up so early (Saturday 9am) to hear my talk. Those of you who missed the talk I went over some of the features of Phishing Frenzy and launched a live phishing simulation. You can see the recording below thanks to irongeek. If your looking to see just the demo, fast forward to 11:52.
PentestGeek Was At Derbycon 3.0 “All in The Family”
Ok so I know it isn’t exactly breaking news that DerbyCon 3.0 was awesome. Still I wanted to take a moment to reach out to any of our readers living under a rock and let them know that last September, the PentestGeek.com crew had an opportunity to represent at one of the coolest Information Security events of the year, the DerbyCon!
Smbexec 2.0 released
We released smbexec version 2.0 a few days ago and it comes with some rather large differences from previous versions. For one thing it was completely rewritten in Ruby, for another it now supports multi-threading.
PowerSploit: The Easiest Shell You’ll Ever Get
Sometimes you just want a shell. You don’t want to worry about compiling a binary, testing it against antivirus, figuring out how to upload it to the box and finally execute it. Maybe you are giving a demo of an awesome new Meterpreter post-exploitation module. Maybe you have less than a minute of physical access to a Windows kiosk machine and need a quick win. There are plenty of scenarios that end in a penetration tester gaining GUI access to a target machine through guessed or found RDP, ESX or VNC credentials. In those situations, the easiest way to get a Meterpreter shell without worrying about AV is with PowerSploit.
PowerSploit is a collection of security-related modules and functions written in PowerShell. PowerSploit is already in both BackTrack and Kali, and its code is utilized by other awesome tools like SET so you may already be using it! Many of the scripts in the project are extremely useful in post-exploitation in Windows environments. The PowerSploit project was started by Matt Graeber who is the author of the function we will use in this tutorial: Invoke-Shellcode.
Pwn all the Sauce with Caller ID Spoofing
If we’re going to perform some pre-text phone calls we have a couple different options when it comes to the caller ID. We really only have 3 possible options which are: we do nothing to the phone number, we block our phone number, or we spoof our phone number.
Doing nothing to the caller ID will sometimes work depending on the area code you call from versus the area code that your client is located in. In my experiences, sometimes not blocking the number yields better results than blocking the number. I always feel like users are more suspicious when the caller ID says ‘blocked’or ‘unavailable’. Not only are they on heightened awareness, but I feel like they are less likely to even answer the phone thinking it’s most likely a telemarketer.
Track User Clicks when Email Phishing
When performing email phishing engagements my clients often ask or want to know what users actually clicked on the phishing email. There are many ways to accomplish this task, but I’m going to discuss the method I use to track each unique visitor to my phishing website.
I prefaced this article in one of my previous blog posts “How do I phish” where I discuss using a ruby script I call sendmail.rb. There is nothing special or magical about the script, it just offers an alternative way to send phishing emails that will assist in tracking each unique visit to your phishing website. There is also value in knowing the CIO or some other C-level executive was just phished.
Scheduled tasks with S4U and on demand persistence
I came across an interesting article by scriptjunkie (which you should really read) about running code on a machine at any time using service-for-user. By changing one line in the export XML of a scheduled task you effectively get a scheduled task that can run whether or not a user is logged in, whether or not the system reboots, whether or not you have the user’s password, run as a limited user, and doesn’t require bypassing UAC! This isn’t an interactive logon but can still be very useful in certain situations.
This works with any user with logon as batch job. While scriptjunkies blog post only showed altering a basic task scheduled to run every hour, it is possible to create more complex triggers based off a variety of things to make a more flexible trigger for your payload. Some of the triggers can even be used to replicate functionality for non-privileged accounts that are usually restricted. Some can even be used to trigger a scheduled task remotely from only your IP address.
How do I phish? – Advanced Email Phishing Tactics
I’m often times asked how I perform email email phishing attacks. Email phishing attacks are very compelling, and unique to each situation. The process of creating a successful email phishing campaign is very methodical, and most of the time and effort goes up front into the planning phase.
Understanding that good security is a multilayer approach and we will have many layers of security that could potentially destroy our email phishing campaign. Some of these layers may include Email Gateway Spam Filters, Outlook ‘Junk Email’ Filters, Host based Antivirus, Intrusion Prevention Systems, Web Proxy Servers, Egress filtering, and the list goes on and on.
