The article is in German and behind a paywall, so it’s all very hard to confirm, but if I understand it correctly, that makes complete sense as an attack vector: Bing Chat “reads” search results by appending them to the big block of text that makes its prompt, so if the results themselves contain something that looks like a sub-prompt… it is liable to respond to that sub-prompt, derailing the user’s conversation entirely, potentially providing malicious links. Oooops.
Want to know when I post new content to my blog? It's a simple as registering for free to an RSS aggregator (Feedly, NewsBlur, Inoreader, …) and adding www.ff00aa.com to your feeds (or www.garoo.net if you want to subscribe to all my topics). We don't need newsletters, and we don't need Twitter; RSS still exists.
