My original guess was that they're intercepting DNS, but since boobs is in the path, it wouldn't be sent. How does this work?
Don't know if this is entirely accurate, but Wikipedia has article about it.
They are giving response codes like 403 so it's not a failure to resolve and I agree it's not DNS... It's behaving differently based on different sub pages so it's something underneath the https encryption. Maybe an intermediary WAF that decrypts? Maybe some weird server side tooling that has govt provided?
I would guess WAF but I'd love to hear from someone who actually knows.
It’s either
Right? If it were an unencrypted HTTP GET request, then every router on the way would see the plaintext string boobs in the URL and therefore intercept it.
If I had to guess, Iran has so few landline connections that they man-in-the-middle every TLS connection they can by either forcing every server to hand over their private key files (difficult) or by forcing a certificate authority trusted by default Web browsers (there's a lot of them) to issue certificates for every top level domain they see in SNI data attached to encrypted packet headers; the latter method need not even require participation by Iranian servers, so long as the traffic is bottlenecked for man-in-the-middle attacks and outsiders don't question unusual certificate authorities being used.
It was annoying as hell trying to download a LaTeX compiler and having the entire word be blocked, presumably because certain degenerates use latex - the material - for immoral acts.
Why with Iran?
Presumably because instead of responding to the request for boobs.jpg with with an HTTP 404 error (meaning, "not found"), Iran's censorship tech returns a 403 error (meaning basically "you are forbidden from accessing this resource).
The "boobs" are "forbidden" you see; the tech mirrors the ruling party's moral stance, probably coincidentally. Trying the same curl command in Russia and China will likely just get you a 404 error, so the joke really only works with Iranian servers. The 404 version is slightly less funny: "We couldn't find the boobs!"
Overwhelming majority of countries don't do keyword-based blocking, especially not for incoming requests.
curl -i https://irangov.ir/boobs.jpg # HTTP 200
curl -i https://president.ir/boobs.jpg # HTTP 200
curl -i https://divar.ir/boobs.jpg # HTTP 404
Can't reproduce. The goverment websites don't even handle the error correctly: they give a HTTP 200 and an error page.
Does anyone have an actual working example?
Lol when I first read your screenshot, I thought for a moment they actually served you boobs.jpg from the government and president sites.
But maybe this is disinformation to make people think servers in Iran aren't?
"Oh boobs.jpg just gives a 404, can't be in Iran!" (When the server is in Iran)
Buddy doesn't even say what domain they figured out was in Iran with this "trick".
First they came for the boobs...
So how do I see the boobs
You put on your robe and wizard hat
Goddamn old people.
Wait. I get that reference. Does that mean I'm an old people?
Send bob and vagene
Sorry, they're in Scunthorpe right now.
I'm lookin at one right now
Also don't be in Iran
You'll find them here https://president.ir/en/president/cabinet
You really need to get out of Iran.
I dunno, but if you find out, let me know.
