WMIC for incident response

Earlier this week, I posted about using psexec during incident response. I mentioned at the end of that post that I've been using WMIC in place of psexec and that I'd have more on that later. This post, is a follow up to the psexec post.

WMIC

Prompted by the excellent work of Ed Skoudis and his part in the Command Line Kung Fu blog, as well as a really nice webcast he did a few years ago titled Essential Windows Command-Line Kung Fu for Info Sec Pros and an Internet Storm Center article from the same year, I've come to rely on WMIC for a large number of IR tasks.

Protecting Admin Passwords During Remote Response and Forensics

PsExec

PsExec has been a great tool for remotely executing processes on a Windows machine. It has been around for years and is one of many useful tools from Mark Russinovich (formerly of SysInternals, now with Microsoft). As described on PsExec's webpage, "PsExec is a light-weight telnet-replacement that lets you execute processes on other systems, complete with full interactivity for console applications, without having to manually install client software."

Digital Forensics Case Leads: The Gauntlet Edition

Greetings Forensicators, Incident Responders and other cool people. I've called this week's article The Gauntlet Edition because a number of organizations have recently thrown down the gauntlet and introduced some cool forensics challenges.Sometimes, the best tool in our arsenal is neither software, nor hardware, nor even our wetware. In many cases, the best tool we can have is a challenge.More than anything else I can think of, it's the process of working a case and rising to a new challenge that really causes us to sharpen our skills. Whether the problem is new to the community, or just new to us, working it through to a solution or an answer is what really causes us to upgrade our wetware.

In that spirit, I've provided a list of recently announced and upcoming challenges, along with our usual assortment of cool tools, good reads and other forensic fun. I encourage you all to pick up The Gauntlet and try your hand at one or more of the challenges listed below.
