Examining static properties of suspicious files is a good starting point for malware analysis. This effort allows you to perform an initial assessment of the file without even infecting a lab system or studying its code. Let's take a look at several free Windows tools that are useful for extracting such meta data from potentially-malicious executables.
Many malware reverse-engineers consider OllyDbg a valuable part of their toolkit. The latest version 1 release of this powerful debugger has been showing its age. Fortunately, version 2.01 seems to be sufficiently mature to start displacing its predecessor as part of the malware analysis workflow. Here's what you can expect when starting to experiment with OllyDbg version 2.01.
As the world of information technology grows in size and complexity, sectors within the IT industry become more and more specialized. Within IT, information security used to be considered niche. Nowadays, saying that your're an infosec professional positions you as somewhat of a generalist. After all, within the infosec field there are several specialization areas, including compliance, pen testing, application security. Even within the area of digital forensics and incident response, many sub-fields have emerged, as discussed in this post.

PowerShell "Remoting" is a feature that holds a lot of promise for incident response. "Remoting" is the ability to run PowerShell commands directly on remote systems and have just the results sent back to the querying machine. From an IR standpoint, this is like a built-in agent ready and waiting to answer your investigative questions--at scale. As I'll discuss shortly, Remoting provides us the ability to query a thousand machine in just minutes!
Before I get to the details of Remoting though, let me kickoff the discussion by going through the basics of PowerShell and Windows Remote Management (WinRM), which provides the foundation for the PowerShell "Remoting" feature. After covering this background information, I'll go over the significant performance benefits of Remoting and then cover the authentication details and implications for privileged account use (fortunately there's a lot of good news on this front too).
PowerShell is the ...
