New data from Microsoft shows Java exploits were the most prevalent in the first six months of 2011. Researchers found that attackers often use exploits for bugs that are several months or years old. The most commonly exploited Java bug during the first half of 2011 was a flaw in the Java Runtime Environment that was discovered in March 2010 and patched within a couple of weeks. Java has been a frequent target for years now, but users don t seem to be doing so well on the updating and patching front.
