https://citp.princeton.edu/research/memory/ https://citp.princeton.edu/research/memory/ A few years ago, I tried this on my own laptop. I didn't have any sort of full disk encryption to test against, so I simply checked the RAM dump for plaintext looking things. Without having cooled the RAM (or opened the computer at all), there was a significant amount of meaningful plain-text. If you are interested in actual data about how effective this is, you should probably ignore my antecedent and look at the research paper in the above link. Given how easy this attack is for its effectiveness, I would be suprised if it is not used.
