PWS-QQRob

An interesting detection via our VirusScan Alert Manager this afternoon. I must say that I haven’t seen this one before, although it was first detected back in 2005 (2005-Feb-25).

The file F:\笭猁訧蹋.exe is infected with PWS-QQRob Trojan.
The file was successfully deleted.

My feeling is that this Trojan password stealer would be targeted at Tencent QQ Messenger users. Being the most popular free IM program in China this would still give you a pretty big target base.

I cannot find any information that outlines if it only targets QQ or if it is a generic password stealer.

Screen Stream (Screen Broadcasting Software)

Screen Stream
Screen Broadcasting Software

ScreenStream lets others ‘watch’ your screen on their computers over the network or the internet. It is the modern equivalent of the overhead projector. When you turn on screen sharing others on your network (or even the internet) can view what is on your screen by typing the link (and optional access code) into their internet browser. They can continue to watch your screen until you turn off screen sharing.

One of the main advantages of ScreenStream is that the viewers do not need to install any special software to view your screen. They just open it directly with their normal internet browser. It is also supports optional streaming audio so others can hear what you are saying.

This desktop screen sharing program is free. It was made as part of our telephone conferencing suite (see phone software) but we now give this software away free as a standalone program for anyone who wants to use it. — NCH Software

Screen Stream is required only by the user who streams their screen, all others are able to view the contents using their web browser.

By default Screen Stream runs on port 89, but this can be changed in the options. You can also set an access code (password) to be required to view the stream.

SUMMARY:
* A good solution for lecturers to use to stream their desktop to other machines within an IT lab environment.
* A great fall back if the projector fails in an IT lab environment.

2Touch IWB

Just back from a demonstration of the 2Touch IWB system.

What is 2Touch? [1]
The latest Interactive Whiteboard to be introduced to the market is the revolutionary 2Touch. Offering a truly unique interactive whiteboard (IWB) experience the 2Touch is comprised of minute cameras located around the surface of the board which detect the exact location of any object approaching the screen. This signal is then used to communicate with a connected computer via USB.

The 2Touch optical whiteboard system uses a standard USB interface and needs no software drivers to be installed, enabling it to operate with any Windows, MAC or even Linux system. Additionally it can be used with any software on your computer, just use your fingers on the board as a mouse and off you go!

- calibration process easy to start from Windows

DISADVANTAGES
- hotspot on writing surface (solve with short throw projector?)
- gap required at top of board (8cm?) to allow for tracking by cameras
- dust/dirt in camera or blocking LED will drift calibration
- calibration via scroll lock key cannot be started from Mac, must press button on board (current version)
