sambazi··on Off-path TCP hijacking in NAT-enabled Wi-Fi networks
imo the protection is real and a good tradeoff for a research project to become a mass medium (i.e. clients usually don't want incoming connections from the internet[1])

don't get me wrong, i like a global address space as much as the next internet native, but it's not for everyone to pay the price for it and nat makes it easy to opt-out of a large portion of the problem space.

[1] my university used to give public-routed v4 to students connecting their winxp laptop to the network; guess what happend

sambazi··on Off-path TCP hijacking in NAT-enabled Wi-Fi networks
there is probably a reason that rp_filter defaults to off though
sambazi··on Off-path TCP hijacking in NAT-enabled Wi-Fi networks
i don't think so because attacker-to-client communication is only used to restore the original nat-mapping.

otoh ap-isolation isn't really a security feature but enhances spectrum efficiency by suppressing client-to-client communication. most wifi's are susceptible to the 'evil twin' attack.

because there are so few of them?

security is never perfect and the bar is rising.

sequence numbers were once considered 'good enough' as prime-factors are today

probably different things, seem my other comment itt

afaik this was done by a modification to the quality-selection algo, not the videos themselfs
sambazi··on H.264 Is Magic (2016)
seems more like gog/yt shifted bitrate/resolution downwards because pleps demand 4k, and now the "High Definition" version that was good enough for cinemas looks like crap.

> Most of the video I see on YouTube these days is in VP9 or AV1. Occasionally some video is still H.264.

can't shake the feeling that most videos at 720p took a hard hit to quality within the last years (or my eyes are getting better)

any deep dives on the topic appreciated

depends; but may i suggest starting at kernel.org then look at 'linux from scratch'/gentoo then maybe slackware; surely not ubuntu

well put

> Genuinely this appears to introduce unnecessary friction. After all, if you can trust the government

but if you can't trust the government, the friction is necessary.

> unable to tie together everything about you just because there's no national ID.

SSN anyone?

tracking for advertising can also be seen as a stop-gap measure against surveillance because the financial incentive for quantity corrupts the quality of the data

PS: you'd also have to spoof the mac addresses and get a lot of clients to report it, but it could cause some confusion
