But a browser escape is different than obtaining root on an OS that doesnt even enable root by default
like I said, different harder attack vector, likely under research
save the argument for someone more in denial about that?
This is a meaningless statement. Just because there is no way to log into the root account doesn't mean there isn't a kernel that treats uid 0 specially.
A linux LPE is worth a small fraction of the money a Firefox escape is. Far easier to come by, far weaker defences.
At least tails seems to use network namespaces now, so deanonymization without root might not be as trivial as it was before.
most of the stuff I find on Tor is very outdated, still enough relevant to piecemeal some decent OPSEC, but being able to bounce ideas of people objectively seems to be lacking - or I don't know the communities
there is the tor reddit page, but reddit is periodically hostile to tor connections. dread on tor is often down, so thats annoying, but I found onion services within tor often had the best information on using tor
/d/OPSEC and dread in general is a cesspit with few quality conversations.
