And will it cover past transactions?

And this is known at least since 2018, as I understand. I am new to #monero, so just having knowledge now, but is this something widely know by the community? What is the sentiment regarding #xmr and this study?

Old paper and fairly sure this vulnerability was already patched, but correct me if I'm wrong Doesn't affect hidden amounts or addresses either. So this is what they would theoretically know: Alice sent ? to ? And it is harder than you might think to sustain this kind of attack.

Thank you and I'm glad it was already patched.
