For anybody not as technically minded, what Phil is saying is that there was a flaw in the forum software that TMC uses. This software is used by a wide number of internet forums, who are all at risk to the same exploit. Unfortunately there will always be a small number of exploits which will be used maliciously before a fix can be applied. To put things into perspective, the site is generally attacked on a daily basis and this is the first time, to my knowledge, that it has ever been compromised.
At the moment there does not appear to be an official fix for this flaw, but Phil has spent a considerable amount of time tracking down exactly what has happened and how best to fix it. The fact that he has provided the authors with his own patch, before an official patch is released, is testament to his own skills and dedication!
In the mean time we would like to recommend that users make sure that both their anti-virus and anti-spyware are up to date. If you do not currently have one or the other installed, then we
strongly recommend you install something such as
AVG Free and Spybot S&D. Personally, I would also recommend switching Internet Explorer for an alternative such as Firefox.
Any further updates will be added to this thread.
Again we are extremely sorry for any inconvenience caused.
