We see again and again that Americans hate freedom of speech. So what is this but a power play? They want people to use controlled platforms where only American-approved activism is allowed. Actions that destabilize an enemy regime.

Iranians who use Signal are American proxy forces. By definition it is treason.

hey. i just thought of something. is it not possible for india or iran in this case to check your phone number and see if it is active on signal? if you are online means you are somehow bypassing their blocks. isnt then just a matter of tracking your cellphone and relevant xkcd applies ? https://xkcd.com/538/ this is looking like a zero sum game unless signal account is delinked from phone numbers because the govt ca…

all they need to do is be in the approximate region of the cell signal through triangulation to figure out the phone numbers / unique identifiers attached to the phone. then its a matter of time before they link real identity to the phone. With the wide availability of femtocells, all they need to do is get lucky once. This puts operators of Signal proxies at potential harms way! Absolutely irresponsible for people o…

How is a proxy operator in harm’s way? They aren’t in Iran, and the Iranian government understands the consequences of trying to do anything about it. Users are in no more danger than they’ve always been, and substantially less than if they didn’t have communications ability.

As far as I know, Iran is much too open an society to actually prevent its citizens from knowing anything in particular. That's not to say it's a free society or that censorship doesn't exist there, just that it's not the sort of regime that is particularly good at it. If I had to guess, Iranian expats would be a likely set of people to start up proxy servers for their family and friends back home.

Yes, which is why Signal is doing a disservice by telling people to announce their proxies on Twitter. The expats should just tell their friends and family, and tell them to pass the word on only to people they trust.

But this doesn't stop them from doing that. If you have an expat friend or family member with a proxy, use theirs, if not, check the latest tweet with the hashtag and use that.

Unfortunately, it's easy for governments to criminalise owning Starlink terminal equipment. Also, Starlink may be legally forced to deny service to users in certain geographical regions.

Unless the government can seize Starlink's assets, or shut down/harm their operations, they can't really tell Starlink to do anything. E.g. if they can shoot down satellites, they'd have influence. This is especially true for economies that are as disconnected from the US as the Iranian one is. The only thing a state has control over is payments from users. But if smuggling in transceiver equipment with pre paid traf…

Starlink will need a license to broadcast in the country. And the dishes also need to transmit which will give away your position.

I'm a big fan of the idea of independently-run proxy servers. Caddy has a secure forward proxy plugin born out of a research project at Google that does something similar, but works with any clients that let you configure HTTP proxies, and doesn't terminate TLS: instead it tunnels it over TLS. The proxy server itself can also be probe-resistant, i.e. difficult to detect that a website is acting as a proxy. I'm hoping…

Does this use TCP over TCP (painful in the face of packet loss[1]) or can you do something like using QUIC for the forward proxy to try to avoid breaking the tunneled TLS connection's retry timers? [1]: http://sites.inka.de/sites/bigred/devel/tcp-tcp.html

It looks like a normal HTTP proxy supporting CONNECT (i.e. TLS over TLS), which wouldn't suffer from the problem you mention.

Note that TLS over TLS is _not_ the same thing as TCP over TCP. TCP over TCP is usually only a problem for VPNs or something similar (i.e. anything that sends raw IP packets over TCP).

Hi, from Iran with love! First of all, thank you moxie and signal team for this proxy. Until 2018, many Iranians used telegram but Iran's regime after Russia blocked this messenger. telegram released mtproxy and this proxy was helpful. Russia lifted the ban on telegram but this app is still blocked on my country. but with VPNs, many iranians still use this app. after 2018, second most popular messaging app in iran wa…

> can they break whatsapp encryption They don’t have to, they just need Facebook to cooperate.

I think you mean the phone vendors, as they are the ones holding the unencrypted chat history in the users cloud storage. Facebook themselves do not have access to the chat logs (unless they are compelled to inject keys).

How flippant. “Almost everyone in these comments is asking questions of various degrees of pedantry or outright dissing hospitals/insurance/medical bankruptcy/whatever... Just donate to a charity if you can spare the expense and help some people out. Action > inaction.” Healthcare and communication aren’t comparable. But my point is that you can criticise institutions for their (contested) faults. If you place yourse…

Your neighbor asks you to drive them to the hospital. Do you lecture them on the failures of privatized healthcare? No, you defer your opinion to the relevant place and time. This right now is about people having their access to uncensored communication cut off, and moxie asking people to help out. If you think their architecture is doomed, you're free to codify your opinion somewhere in a pull request or comment und…

The analogy falls a bit flat because this forum contains, mostly, the arbiter of the root problem- namely that signal is not censorship resistant by itself. And we should criticise them for that because it was a warning delivered in a timely manner and never heeded.

Helping my neighbour in this case means allowing them to use my social insurance. Namely by using xmpp/matrix. It is low/no cost to them (unlike moving countries for socialised medicine.)

In light of all the government Internet shut downs in the past years, I’m very curious to see the impact of star link and other Connection methods that might bypass geographic restrictions. Will SpaceX and other service providers shut down access when local governments request it? If not,Will the governments ask on a perceived threat to stability

Iranians who use Signal are Iranians. Your statement is premised on the Iranian government having absolute authority to surveil the communications of Iranian citizens. By that logic, any from of end-to-end encrypted communication is treason. You might as well say that Iranian citizens have no general right to privacy and any expectation of such is also treason.
