Having your network environment protected with the latest virus protection, control what software is installed and allowed to run, restrict ingress and egress network access, protect web browsing, limit user account access, update security patches, change management practices, etc. All these efforts are critical to follow in the corporate environment but all will fall short if you don't have the proper monitoring in place to detect badness on your network and to respond quickly and effectively when it happens. When your network has the proper monitoring in place and knowledgeable engineers to monitor for outbreaks you will begin to have better visibility of how network traffic flows in your environment. When you understand how traffic flows on your network you can respond better when badness happens. I will demonstrate how to use a number of tools to analyze a memory... (more)

Malware Analysis | Part 2

In a previous article [1], I described how to obtain a memory image from a Windows computer that would allow forensic analysis. I briefly discussed using F-Response TACTICAL [2] to get the memory image, and then Volatility [3] and Mandiant Redline [4] for further investigation. In this paper, I dive more deeply into Redline and Volatility. To begin, I review a raw memory dump of a known malware variant (see the "Malware Image" box) with Mandiant Redline. After firing up Redline, I chose By Analyzing a Saved Memory File under Analyze Data and browsed to the location of the memory... (more)

Post Exploitation Using Metasploit Pivot and Port Forward

The Metasploit Framework is a penetration testing toolkit, exploit development platform, and research tool. The framework includes hundreds of working remote exploits for a variety of platforms. Payloads, encoders, and nop slide generators can be mixed and matched with exploit modules to solve almost any exploit-related task. A very nice feature in Metasploit is the ability to pivot through a Meterpreter session to the network on the other side. This tutorial walks you through how this is done once you have a Meterpreter session on a foreign box. We begin right after a client sid... (more)

RDP Exploitation Using Cain

The Microsoft Remote Desktop Protocol (RDP) provides remote display and input capabilities over network connections for Windows-based applications running on a server.  RDP is designed to support different types of network topologies and multiple LAN protocols.  Remote Desktop Services formerly know as Terminal Services on Windows 2000 Server allow a server to host multiple, simultaneous client sessions.  Remote Desktop uses Remote Desktop Services technology to allow a single session to run remotely.  Thus a user can connect to a Remote Desktop Session Host server by using Remot...
