This is the week of Black Hat and Defcon, which means a flood of news coming out of the Las Vegas security conferences. As you might expect, artificial intelligence was one popular topic--specifically, using AI chatbots to cause mischief. One team of researchers, from Tel Aviv University, created a clever attack that allowed them to take over a target's smart home devices using a "poisoned" Google Calendar invite. It's the first known attack method that used AI to impact physical devices. Another researcher used a poisoned document that included a malicious prompt to trick ChatGPT into leaking a user's private information when it's connected to a Google Drive.
