The paper (https://hannesweissteiner.com/pdfs/frost.pdf) cites two earlier papers (from 2014 and 2017) that did the same for HDDs.

I laugh at your spying attempts from my cURL e-mail service that I use instead of a web browser.

Or mine where the entire browser profile is on a ramdisk.

Higher IO latencies in HDs might actually make this attack easier - more contention means more bits of data.

I got $HOME in a huge HDD because it was cheaper. I guess we belong to the cool kids club now?
