Introduction 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. This tutorial will walk you through how to use the latest version of Nessus pre-built plugin filter ‘Metasploit Framework' in your pentest assignments. It will also cover some useful metasploit tips to achieve privilege escalation. Wouldn't it be great to have a shell on another box just in case you lose your meterpreter shell? This tutorial covers this and other metasploit tips. Integrating Nessus 5 with Metasploit With the release of Nessus 5 by Tenable Network Security users now have better filtering in policy creation, analysis,... (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)

Capture File Filtering with Wireshark

Intrusion detection tools that use the libpcap C/ C++ library [1] for network traffic capture (such as Snort [2] and Tcpdump [1]) can output packet capture information to a file for later reference. The format of this capture file is known as pcap. By capturing packet data to a file, an investigator can return later to study the history of an intrusion attempt – or to turn up other important clues about clandestine activity on the network. Of course, the traffic history data stored in a pcap file is much too vast to study by just viewing the file manually. Security experts use spe... (more)

Planning, Scoping and Recon Techniques

The purpose of this article is to describe some tools and techniques in performing the planning, scoping, and recon portion of a penetration test. In covering these tools and techniques the reader will learn how to use them to find vulnerabilities in their organization and help improve security posture. Some other names for this first phase of penetration testing are; OSINT (Open Source Intelligence), Footprinting, Discovery, and Cyberstalking. Introduction During reconnaissance we'll gather information from public sources to learn about the target and try to find what is importan... (more)
