In February, I posted about a potential Vista glitch that could allow ad banners to manipulate Vista Speech Control. Two more recent articles about rogue ads:
WSJ: "In a development that could threaten the explosive growth of online advertising, hackers have started to exploit security holes in the online-advertising chain to slip viruses into ads. Just going to a site that shows such an ad can infect a user's computer."
Associated Press: "Hackers could take control of an iPhone if its owner visits a doctored Web site or Internet hotspot, security researchers reported Monday. "'You could have a million iPhones dialing the company's main line and overwhelm it that way," [a security analyst] said."
I'm filing it under the "formats" tag, but don't get any ideas.
