I recently landed on a client’s network with an implementation of Microsoft LAPS on a few thousand hosts. This blog post will walk through how to identify the users sysadmins delegated to view LAPS passwords, and how to identify the users sysadmins have no idea can view LAPS passwords.
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.
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.
The latest version of WordPress, version 3.5 was recently released on December 11, 2012. This latest version of WordPress comes pre-packaged with the XML-RPC interface enabled by default. This is just the type of configuration that us pentesters love to see during an engagment. This additional attack surface may be just the little extra that a pentester needs.
Metasploit Module 
I recently added a post exploit module to the metasploit framework. The module will extract and decrypt passwords that are stored by the Spark Instant Messenger client. The passwords are stored in a file on the local HDD (spark.properties) using Triple DES encryption. This sounds all fine and dandy, but this all goes out the door when they hardcoded the key and made it publicly documented.
The vulnerability isn’t that new since it was documented by Adam Caudill back in July 2012 when he disclosed the details and PoC code in .net that illustrates how the attack can be completed. Mubix recently submitted a request to add this post exploit module into the framework. Well, SmilingRacoon and myself decided to answer the call and work up a module to accomplish this task.
Harvesting email addresses is a common part of any external penetration test. Several tools exist that can be easily found with a simple google search that can greatly decrease the amount of time spent combing through search engine results.
I have recently released a new tool into the BackTrack Linux penetration testing distribution that has proven useful on many of my external gigs.
Introducing Jigsaw. Jigsaw is a simple ruby script that searches www.jigsaw.com for employee records and crafts email addresses based on first and last name entries pulled down from their website.
Recently I was conducting a penetration test for a very large high profile client. The last thing I was expecting to find was SQL Injection . The network itself had over 5500+ nodes and nearly 400 subnets. I started out using one of my new tactics by utilizing Nmap’s new http-screenshot.nse script. If you haven’t had a chance to check it out; I highly suggest you do, its the new hotness. The NSE script essentially allows you to scan a network with nmap and take a screenshot of every webpage at the same time. Tutorials on how to use the script can be found on Pentest Geek here, or on Trustwave’s site here.
SQL Injection – Initial Identification
Normally when looking over all of the webpage screenshots I’m typically conscious of items like Apache tomcat servers with default creds, Jboss servers that expose the jmx-console, printers that have internal document servers holding confidential data, etc, etc…Read More
It seems that more and more these days I find myself battling head to head against my client’s Antivirus Detection capabilities. Payloads I encoded to successfully bypass one solution get picked up by another. An executable that walked effortlessly past one AV this week gets stopped dead in its tracks by the very same software build at a different client the week later. This is a frustrating and constant problem for myself and many other Penetration Testers I am sure.
The topic of Antivirus Detection bypass is not a new one by any means. Currently there exist several methodologies that work well and I don’t think anyone (at least no one I know) can respectfully make a claim for a particular method being the De facto standard that works every time.
This article aims to provide some insight into one such method that I have become fond of and has proven quite successful in many of my recent Information Security Assessments. I first became aware of the technique by reading This Great Writeup from exploit-db. I’m not sure if the author is responsible for coining the term or not but they refer to this ancient wisdom and all of its magical powers under the alias “Ghost Writing” which I think sounds super cool!
