Fun with malware

blufiveI've had a fun time in the last 24 hours with a piece of malware that managed to install itself via Firefox and a Java applet. Breezed straight in, installed a nasty IE toolbar and hijacked IE.
Having poked and prodded extensively, the security hole was in Java, and was fixed between Java 1.4.1_01 (which I was using yesterday) and Java 1.4.2_05 (which I'm using now).
Moral: If you have Java enabled in Mozilla/Firefox on Windows, update to the latest Java Runtime right now unless you like the idea of websites being able to execute arbitrary code on your machine.
