IMPORTANT - Easily Protect your PC and your Client's against this ZERO DAY exploit
By Andrew Pollack on 12/30/2005 at 11:35 AM ESTA flaw in a special kind of image viewer for viewing WMF files represents an unpatched security risk -- and that risk has been exploited in the wild already. All someone has to do is send you an email with an image of this kind containing the exploit to infect your machine. The way worms and viruses work, the person you get the email from may not have even known they sent it.
To protect your computer, simply click "Start" then "run" and type "regsvr32 /u shimgvw.dll" and click "OK". This will "unregister" the viewer which contains the flaw. You'll be unable to view WMF files, but very few of these are used. It is unlikely you'll notice a difference.

Unlike most worms and viruses, this is one which to which the Lotus Notes client is also susceptible because it also uses Microsoft's viewer library for these kind of files.
Note: Thanks go to Ken Yee for pointing out this easy fix.
attachments (though it will view them)
- if a program is registered to handle the .jpg extension, launch it
- else use Windows Explorer's preview crap shell to launch it (shimgvw.dll :-)
isnt releasing their patch until next Tuesday. Lotus needs to address--or at
least acknowledge this.

The truth is, I haven't had much to say that was worthy of more than a basic social media post -- until today. For my current work, I was assigned a new laptop. It's a real powerhouse machine with 14 processor cores and 64 gigs of ram. It should be perfect for running my development environment in a virtual machine, but it wasn't. VirtualBox was barely starting, and no matter how many features I turned off, it could ......

Certainly it should have been addressed in the Trump, Obama, Bush, Clinton, Bush, and Reagan administrations -- all of which were well aware of the implications of a pandemic. I want a military prepared to help us, not just hurt other people. As an American I expect that with the ridiculous funding of our military might, we are prepared for damn near everything. Not just killing people and breaking things, but ......

This is not quite a scam because it's technically legal, but it's run very much like a scam. This company works with a few "clients" that have vast repositories of copyrighted images. The trolls do a reverse web search on those images looking for hits. When they find one on a site that looks like someone they can scare, they work it like ......
