  • Managing IE Sites for EMET with ASR (Attack Surface Reduction)

      If you haven’t started testing EMET 5.0 please consider doing so especially if you are charged with piloting the product for your organization as this version is the latest and has more fixes and protections than are available in the 4.x platform...
  • Setting EMET Local Configuration via GPP

    Our PG released EMET 5.0 yeah and it works pretty well and has some cool new functionality such as actually blocking on pin rules and the new ASR feature which I feel is very cool too. A big fix was the fact that there is a service now and that service...
  • Troubleshooting an EMET Mitigation Application Crash

      In the process of deploying and piloting EMET there is a definite possibility that a legitimate application will not function properly with EMET. Lets try to set some expectations here there are basically 2 things you can do when this occurs: Work...
  • Configuring EMET via GPO/GPP w/o using the ADMX files

    [UPDATE 7/23/2014] I've create a wiki page at http://social.technet.microsoft.com/wiki/contents/articles/25585.emet-gpo-gpp-using-task-scheduler-to-import-emet-settings.aspx that condenses these steps and adds a few new items and is open to collaborative...
  • Xpath Event Log Filtering

    So I’ve been working on some stuff lately with Event Log Forwarding and Auditing in general and have come to realize the goodness of using Xpath filtering… you know that “XML” tab you never look at when filtering your event logs There are other great...
  • Automatically refreshing EMET GPO’s

    If' you’ve tried configuring EMET via GPO’s you’ve probably come to realize that while the GPO’s may process normally and change registry keys locally on the system it does not actually affect the running configuration of EMET.   From the...
  • Restricted Admin mode for RDP in Windows 8.1 / 2012 R2

    So we released some information a couple of weeks ago on the upcoming OS releases that mentioned various security features that will be built into the new operating system. Specifically one that was mentioned at a briefing at Blackhat was a Restricted...
  • Another WSUS Cleanup Script

    Just noticed this as I was looking for a solution for a different WSUS problem and thought I would share this here as well.  http://gallery.technet.microsoft.com/ScriptCenter/en-us/90ca6976-d441-4a10-89b0-30a7103d55db Apparently a “Thomas Schlacter...
  • Some thoughts on Adobe Reader and malware

    Not sure if anyone saw this bit of news recently where a report put out by ScanSafe indicates that PDF’s accounted for 80% of exploits in the 4th quarter of 2009 .  I support both FCS our antivirus product and I also do Incident Response work. ...
  • Some more logparser & eventcomb stuff for IR work

    Counting and sorting by unique text in the strings section: As a follow on to a previous article http://blogs.technet.com/kfalde/archive/2009/01/28/using-logparser-eventcomb-to-find-malware.aspx I found some other useful queries that I figured I would...
  • Determining the cause of FCS client performance issues

    Realistically this process should work for other AV clients as well but I’m doing it in the context of the one I support.  Although it isn’t extremely common we do run into scenarios where customer has issues with the FCS client taking up large amounts...
  • Logparsing FCS to find files that were infected

    Working an interesting case at the moment where we have multiple files across servers that were infected and we are needing to generate a list of all the files that were infected on each server. So the first thing to realize is that the 1006 and 3004...
  • Rare off-topic post :)

    It is currently MS’s giving campaign where we promote philanthropicness :).  A coworker sent this out to our internal blogger alias along with some others from this site that various MS MVP’s and internal employees worth with asking if we could post...
  • Dealing with malware that creates .exe’s on file shares

    So lately we keep seeing variants of malware that modifies content on file servers in an environment in hopes of spreading to other users.  My guess is that it is just using mapped drive letters thinking they are USB keys but the effects is the same...
  • How to go green with FCS

    I’m not a treehugger but I can definitely see the $$ with power savings. Having said that I had a customer recently that wanted his computers to wake up from sleep in order to do their scheduled scans for FCS. At first I was like nope not possible we...
  • Some Interesting FCS SQL Queries

    With a recent case I have an issue where the client count of managed computers in MOM admin console was quite different then that in the FCS console so I was trying to find out exactly which computers were not in FCS so I could troubleshoot some of those...
  • Update Views for FCS in WSUS

    Nothing profound with this post just detailing out a step I typically recommend to most of our new customers with regards to making life easier when viewing updates in WSUS.  In order to make your life easier viewing FCS inside of WSUS I typically...
  • Cheap real time monitoring for Conficker clients

    I already did one post about using eventcomb/logparser to look for clients but found a better way to do it on a case last night which I wanted to share.  The first thing you need is to enable netlogon debug logging on all of your DC’s save the following...
  • WSUS FCS Definitions

    This is a follow up post to my previous FCS definitions post.  The first one focused on the mpam-fe files and what is contained that you can find on the security portal at www.microsoft.com/security/portal .  This one instead focuses on what...
  • Blocking and finding Conficker and Downadup systems

    EDIT 4/27/09: THIS NO LONGER WORKS WITH NEW VARIANTS OF CONFICKER HOWEVER THE CONCEPT IS STILL SOUND IF YOU ARE LOOKING FOR SYSTEMS THAT ARE QUERYING FOR SPECIFIC DNS NAMES.   I’ve already created one post on finding malware systems using eventcomb...
  • Understanding FCS Definitions

    A fairly frequent question we get is how do FCS definitions work. How do I find just the delta’s for the month etc. You can always manually download the latest definitions from http://www.microsoft.com/security/portal with the links on the right. This...
  • Using Logparser + Eventcomb to find malware

    During the course of these Conficker / Downadup issues we typically see cases that started because accounts are getting locked out.  I pause briefly here to point out that account lockouts are the work of the devil and are a sorry excuse for most...
  • How-to: Removal of Conficker in your FCS environment

    Another Conficker post :) however this one is aimed at our FCS customers. It semi-applies to other customers however other AV vendors operated differently with regards to updates etc so this won’t necessarily be applicable to all. So today is Patch...
  • More on File Shares and Autorun.inf with regards to malware

    So in my last post I mentioned the fact that Conficker/Downad whatever can also have a component that will spread through file shares that allow everyone to write at the root level of the file share. So a typical autorun.inf looks something like this...
  • Malware Win32/Conficker.B W32.Downadup.B

    So for the past 2 weeks now we are absolutely getting hammered with calls in CSS Security here at MS with organizations contracting this piece of malware. You can find write-ups from various AV companies at the following URL’s http://www.ca.com...
