The New Trojan War

Microsoft has released it's Security Intelligence Report for July through December.  There are some interesting conclusions in this report such as

 

During 2H07 the MSRT proportionally cleaned malware from 60% less Windows Vista-based computers compared to computers running Windows XP Service Pack 2.
Similarly, the MSRT proportionally cleaned malware from 87% less Windows Vista-based computers than from computers running Windows XP with Service Pack 1 installed, and 91.5% less than from computers running Windows XP without any Service Pack
installed.

The most significant statistic in this report however is the increase in the number of Trojans.

During the second half of 2007 there was a 300% increase in the number of trojan downloaders and droppers detected and removed. The increase observed in 2H07 is vastly larger than the already large increase observed between 2H06 and 1H07. Clearly this category of malware has become a tool of choice for some attackers. IT Professionals and Security Professionals alike should become familiar with this type of malware so that they can better protect their networks from attacks that leverage it.

Be careful everyone and make sure your anti-virus is up-to-date and you do not open email attachments or visit sites you do not trust or know.

Radon in Newry, Mourne and Down - Action & Education Needed

Council budgets have been and continue to be slashed and perhaps that's the reason why more is not being done to educate people on the risk Radon gas is posing to their health in the area of Newry, Mourne and Down. A recently published Government report includes the below map which starkly highlights the huge areas of the district that are potentially exposed to high levels of this naturally occurring radioactive gas.



While the UK Government recognises and highlights the role this gas plays in causing lung cancer the EPA in the U.S. goes further adding numbers and additional facts such as : 1. 21,000 deaths a year are linked to Radon gas in the U.S.  2. It's the second biggest cause of lung cancer after smoking 3. Radon can enter the home through the water supply as well as the soil 4. There is a risk of stomach cancer from ingesting water containing Radon and lung cancer from inhaling the gas carried in the water.
To help protect and educate the population it's time the c…

A Little Time Travel Thought Experiment

During the Back to the Future (BTTF) anniversary celebrations there was a lot of talk about how accurately they represented time travel. The consensus seemed to be that travelling back and appearing at the same physical location but in a different time was how time travel would likely work. This is where I got thinking. The universe is an ever moving beast. Nothing sits still and this leads to some pretty big problems. To start with the Earth rotates on its axis every ~24 hours, so our traveller would need to arrive at approximately the same time of day in the past. He’s worked out time travel so that’s not going to be hard to do. Next, the Earth orbits the sun every ~365.25 days. This one is a little more of a problem. If our traveller is in the heat of June and has decided to travel back because he wants to see an Xmas in the past he’s got a problem. The Earth will be on the other side of the Sun. So Marty needs to travel back to roughly the same day each year? Fair enough I suppos…
