After the Hamachi article I wanted to do a series on OpenVPN. I’ve used it before, but not since the 1.x days…. it’s now at version 2.0.5 and has quite a bit more flexibility. When I first used it, it was pretty much a point-to-point vpn solution. You could set up routing to see the […]

There’s a bit of controversy over the suggestion that Hardware DEP seemed to protect against the WMF zero day exploit. Sunbeltblog has responded to the controversy. George Ou in the first link above claims that there’s a lot of bad advice out about this exploit and that hardware DEP (Data execution prevention) doesn’t work to […]

Sorry, but to get into the guts of what I found in the wake of the WMF exploit, I did leave out another important step in the cleanup process. IF you are trying to clean up an infested machine one of the first real goals has to be disabling system restore. (start, (settings,) control panel, […]

I haven’t checked to see if these are already on other block lists for the WMF exploit, but the following addresses are advised to be blocked (from f-secure)…. toolbarbiz[dot]biz toolbarsite[dot]biz toolbartraff[dot]biz toolbarurl[dot]biz buytoolbar[dot]biz buytraff[dot]biz iframebiz[dot]biz iframecash[dot]biz iframesite[dot]biz iframetraff[dot]biz iframeurl[dot]biz    Send article as PDF   

One other note from the previous series on WMF exploit infestation cleanup. Among the multiple popups that came when launching internet explorer, most were directed at the site http://60.topnssearch.com –    Send article as PDF   

Can I say enough times that after a bad trojan infestation you should format and reinstall? I’ve cleaned up the infested image that I “sacrificed” to the WMF exploit and as I’ve said you’re pestware install will likely be somewhat different. An exploit is just the road, the spyware and viruses are the cars. Once […]

Browser helper objects (BHO’s) are listed in the registry and load with explorer when it runs (Internet Explorer/ File explorer are so closely tied it affects both.) I’ve used BHOdemon in the past to identify and disable BHO’s and a tool like that is the preferred method. However, in my case, this is a disposable […]

So, I’ve got most of the baddies cleaned out and I’m not getting popups anymore. No nags on boot, the boot process is quicker, but is it really clean? I found a few files (winlogon.exe, alg.exe in particular) that could be legitimate windows file names. Am I running the good one, or the trojan? That […]

At this point, I needed to rename or delete some files that windows would not let me touch. I had this winlogon.exe running from a suspect directory c:\windows\inet20001 and windows wouldn’t let me kill it, or remove it’s start entry in the registry. So, I booted my image from a dsl linux cd and opted […]

OK, so, I’m busy killing off running processes and fire up MSConfig to try to keep them from coming back on the next boot. To launch msconfig go to start, run… type in msconfig and click ok. The startup tab is where we’re looking for programs running at startup (makes sense…) This is a bit […]
