This is a fascinating use of a #sidechannel timing attack against calls to an #AI model.
By capturing encrypted TLS traffic and measuring timing, they can _very accurately_ determine which streams corresponded to an LLM conversation about a pre-selected topic.
TLS is intact. So their ability […]

Apple Computer launched their own line of chips a way back. Unsurprisingly, there are some security flaws. While these are pretty bad they are not insurmountable and hopefully Apple will release updates to address the issues quickly.
