[edit] Synopsis
Chris looks at viruses in a VM, not just a few, but a plethora of them. Christine shows us a quick trick in Google Chrome. Shannon is showing us Photosynth for creating a 3D model of a room. Darren shows us how to rig up a cheap mini multitouch system.
[edit] Segment One: Viruses in VM
Chris explains two sites that are extensive databases of malware and offensive computing. He shows the process tree and monitor before infection showing very few tasks running.
To start the "testing" Chris hides all the existing processes before infecting the machine. Chris initially starts mydoomF.exe and uses sysinternals to see what is happening in real time. MydoomF starts hooking into winsock, and a whole bunch of other dll files. Sysinternals also shows registry edits occurring.
mydoomF actually manages to kill taskmgr.exe and its on hell of a time trying to figure out what process is the virus. Chris and Darren explain that notepad.exe is actually where mydoomF is actually existing.
Sysinternals process monitor and process explorer luckily are secondary program for taskmgr allowing the kill off of processes and give a much greater insight of what is going on on a more advanced level. Check the links below from the segment for more info.
[edit] Segment Two: Multitouch mini with Darren
Darren shows us how to build our own multitouch unit out of a cardboard box, paper, web cam and a photoframe. Thanks to Falcon for this segment.
How does it work? There is a webcam in a cardboard box pointing at a white piece of paper enclosed in a photo frame on top of a box, enclosed so that no light can get in. Pretty awesome eh?
Darren uses the multi-touch mini package that lets you calibrate the multitouch mini to the point where the finger becomes a single point instead of a massive hand.
After this, you need to run the server application and the gateway that allows demo applications to inteface with the multitouch mini.
In the demos folder that is provided by the multitouch mini package there are a series of demos. Some of the games shown are multitouch pong, multitouch musical keyboard and a few others. Darrens Aspire One fails in this, so word is run the multitouch on something that has a bit of power for processing, like a desktop. Check the original blog post where this project originated from below.
[edit] Segment Three - Christine on Web Browsers
Christine talks to us about Google Chrome and the Google about memory. What is this? In chrome if you type in about:memory in the address bar we get a similar function of task manager that shows us where all our tube memory is going. Whats awesome about this? Well it will actually get the memory use from your other browsers, giving you a good indication of which is better memory wise if thats what you really want to find out.
You can get Google Chrome from the link below [6]
[edit] Segment Four - Shannon on Microsofts Photosynth
Photosynth puts all the different photos of a certain area into a 3D type model. First of all you will need to get photosynth from the link below. Shannon explains to us that to manage to get a 3D model of an area we need to get lots of photos with overlapping scenery. Some issues explained are that the angles can not be too odd otherwise the program gets confused.
Matt lets us know that creating the 3D model can take quite a bit of time, as he explains roughly about 45 minutes to do 190 photos of the Hak5 set. Shannons got the finished result on her blog. Check the links below for Photosynth and Shannon's blog.
