A few days back I was at grc to run a “shields up” scan on a clients machine and found reference to their Security Now podcast (Leo Laporte and Steve Gibson.) The cast was about a VPN tool called Hamachi… so I revisited and gave a read to the Security Now! transcript. And then visited […]

This may be one of the most important entries in this series. An important defence against those that would try to access your network is to constantly have the “security mindset”. Ask yourself “do I need this, how could it be exploited, what are the implications of this”… When it comes to people asking you […]

I notice that the Sunbelt Blog has some instructions up for blocking the zero-day Windows Meta File (WMF) exploit with their newly acquired kerio firewall. (Free or full version.) Either version can use an add-on rule from bleeding-edge snort (intrusion detection signatures…) Instructions in the link above on how to implement the rule addition.    […]

You had to know we couldn’t make it to the end of the year without another story about the Sony DRM rootkit…. I noticed last night that the sunbelt blog had mention of a proposed settlement in their legal troubles in the wake of the XCP copy protection DRM rootkit MESS. *(Mediamax is not quite […]

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 […]
