I've read some information from 2014-17 about attacking possibilities which have or had nodes are called ''HSDirs''
At first what i need to know, HSDir node it is also ''exit'' or third node from client, isn't it?
At second, as authors of researches have said, malware HSDirs can be able to (or were be able to) know V2 onion's adresses, which clients connecting to, but what about user's IP? Can they deanonymize client/user or easily compare client request IP's and URL's of onions?
At third, is V3 so much better than V2? Because as far as I know from 2013 documentation, only 2 nodes (first and third) needed to easily deanonymize V2 onion user. Or in 2020 2 nodes are not enough?
Thank you so much. Shukriya
