what's most interesting to me about this research is that it is an online collaborative one. I wonder how many more project such as this there are, and if it could be more widespread, maybe as a platform.
This comment reminded me to check whether https://www.distributed.net/ was still in existence. I hadn't thought about the site for probably two decades, I ran the client for this back in the late 1990s back when they were cracking RC5-64, but they still appear to be going as a platform that could be used for this kind of thing.
I'm not clear from the doc which of these scenarios is what they're calling the "leak"
