Why you should run BitMessage as a TOR Hidden service.

It's probably more secure. I run a .onion BM node 24/7 with no clearnet connections, just Tor in and out. The way I communicate with BM is by connecting *only* to my .onion BM node using the little-known trustedpeer feature. Works really well since the .onion node is always up to date and my python client quickly downloads the latest messages, decoding subbed chans and person-to-person messages.

Running as Tor only also prevent global passive adversary from seeing origin of chan posts and broadcasts. Now with Tor node in BM you can now have green light and not just be a leecher. And.... what is the trustdeeper feature?

Agreed. We should all take the few minutes needed to configure BM with TOR Node as a Hidden Service, in order to really be able to post anonymously. FUCK THE NSA & FRIENDS.

Thank you. About the parameter "socklisten = true" (Accept TOR + clear net connections ) instead of "socklisten = false" (Accepted only TOR connetions) , Here is my question : It is clear that in order to post more anonymously (Using TOR), it is required to set it to FALSE. But is there a risk of being "isolated" in a sub bitmessage network run by feds ? Just telling you this because it is said that more and more TOR exit nodes are run by feds. Then, just a word about this : TOR hides IP address, making one more anonymous on the network, BUT remember that it is only "more" anonymous. There many other fingerprinting based identifications technics that TOR cannot fix. The most dangerous fingerprinting identification technics rely generaly on Hardware characteristics, or integrated circuits unerasable, unmaskable, unchangeable serial numbers. All those fingerprints are unique to a computer, and if your computer has been infected by a malware that transmits those funcking fingerprints "within" your legit TCP/IP traffic going trough TOR, in some hidden channels at TCP/IP level, or at protocols of higher levels, meaning "tagging" all your TCP/IP traffic with your fingerprints, without your knowledge (And it's almost impossible to detect slow hidden channels) then, an agency like NSA doing DPI at all exit nodes can still identify who the traffic is coming from, without the need of IP addresses. All those fingerprints, linked to hardware caracteristics or integrated circuits serial number are intensively collected all the time by those agencies, associating them to your identity. Never forget this. The only way to use TOR and ensure those fucking fingerprints won't betray you, is to buy, in cash, dedicated hardware, whose serial numbers and hardware caracteristics were never associated to your identity before. Please do note that in a computer, one find about 20 unique serial number embedded into most integrated circuits and subsystems. Displays have serial numbers. 95% USB peripherals have serial numbers, particularily USB Flashdisk keys. Processors have serial numbers. DDRAM modules have serial numbers.

All consumer market printers print serial numbers microscopically on every sheet of paper run through.

So that any effective propagandist can be identified by state organs and silenced.

I've heard about this, but as far as I understand it all depends on browser vulnerabilities or bad design. Bitmessage isn't a browser, it's not affected by these attack vectors. Even if you click on View HTML, this will only interpret a subset of HTML, and network transports aren't implemented. So if you have, say a "img src=http://..." in the message body, it won't load at all. > Please do note that in a computer, one find about 20 unique serial > number embedded into most integrated circuits and subsystems.

Dear Peter, I forgot to tell you something about the fingerprinting identification risk / probability : Of course the main attack surface for such identification technics with TOR or VPN's are Web browsers and their complexity that bring a huge attack surface for an attacker to infect your computer with a malware that would transmit those fingerprints within hidden channels within your legit TCP/IP Traffic. But we could also think NSA has more vicious plans about this : Here is a possible scenario : All our computers may already be tagging TCP/IP traffic with fingerprints for a long time ago : Such tagging malwares may have been implanted on our computers a long time ago. In the Chipset, in the Bios, or in many other parts. As we don't know yet, the best thing we can say about it : The way to reduce or stop the attack surface with fingerprinting identification technics, is to use protocols that don't allow any attack surface to implant hidden channels on them : Everything turns about being able to have protocols that can hide an hidden channel or not. - TCP/IP "alone" can be used to create several kinds of hidden channels, but all this is perfectly known and has been deeply studied for long : We know exactly where hidden channels can be constructed on TCP/IP, so let's say it would be risky for NSA to ue hidden channels on TCP/IP itself because it would be more easily discovered. But it doesn"t mean they don't do it either. Then, if you want us to estimate the risk and the probability, it would be interesting if you could list us ALL the protocols BitMessage is effectively using with all the Libs you are using. I guess there is SSL / TLS, or those implied in BitTorrent and BitCoin. Listing the protocols allow us to asses the risk of having hidden channels built on them. In this regard, BitMessage is by design very secure at his application level against hidden channels, because you encrypt everything, but what I tried to say, is that it may not be the case for the underlying protocols it relies on. Then, a last word about this attack surface and how to reduce it : Let's imagine NSA & friends manages to build a hidden channel that would allow to identify the sender of a message. Even if we don't know where this hidden channel is implanted, we can assume that it is a very slow hidden channel that only transmit a kind of UUID fingerprint. Time comes into play : In order to work, the fingerprinting identification technics need to be able to gave the time to transmit the whole UUID into its hidden channels. A way to prevent that is to make short socket connection that transfer only short amounts of data, not enough so that the hidden channel can transmit the whole UUID. There may be other ways to do it. Anyway, the goal of my message was to warn you about this, so that you could keep this issue in mind for the future... Ther may be a few things you could improve regarding this. The second goal of my message is to warn VIP users that it is possible to have a workaround of these hardware based fingerprinting identification technics, simply using dedicaded hardware (Raspberry Pi) whose hardware caracteristics and serial number where never associated to one's identity. But the readers of this message will understand that the security procedures neeeded to ensure this are very strict. Any mistake not only uncovers your identitity for the current session, but all previous sessions too. I wanted to teach people about this. Because for people like "Snowden class whistleblowers", they need to know that it is possible to bypas those fingerprinting identification technics, but that the security procedure to apply and to stick with are very strict, and costy. Still, it would be interesting to make an estimation of the possibilities of building hidden channels over the protocols used by bitmessage in order to estimate the true benefits of using TOR with BitMessage. Intuitively, I think the benefits are huge, but all this indeed depends on the analysis of the possibility by NSA & friends to build hidden channels on all the protocols BitMessage relies on. Kind regards, Stman.

I > guess there is SSL / TLS, or those implied in BitTorrent and > BitCoin. Bitmessage has its own protocol, described in the wiki. I'm now redesigning the network subsystem, and that includes the protocol parser so it's less error-prone to use. TLS is optional, but eventually it will become mandatory. It occasionally uses other protocols: - SOCKS if configured, in that case all BM traffic is tunneled - DNS for bootstrapping (when SOCKS is on, uses tor's RESOLVE extensions instead) - UPnP for port forwarding (only a subset is implemented, not full UPnP) - XMLRPC for API, if turned on I'm also adding LAN peer discovery, but it will also use the BM protocol, just on UDP instead of TCP. UPnP and XMLRPC are off by default. The GUI (PyQT) has theoretically the capability to add protocol handlers, such as HTTP, as helpers for rendering messages. But as I said before they aren't implemented in PyBM and I don't plan on doing that. > In this regard, BitMessage is by design very secure at his > application level against hidden channels, because you encrypt > everything, but what I tried to say, is that it may not be the case > for the underlying protocols it relies on. There is very little that can be misused. Even the TLS uses on a subset of available features, and out of the attacks publicised in the last couple of years, as far as I understand, only Heartbleed would have affected PyBitmessage (because you weren't able to turn it off without recompiling OpenSSL, and sadly this was still the case last time I checked). Most other vulnerabilities depended on a browser anyway. The rest were things like TLS protocol downgrade, that wouldn't have worked as PyBitmessage requires at least TLSv1 (I would have insisted on TLSv1.2, but python < 2.7.9 doesn't allow such a setting). Now when I think about it again, maybe what I could do on python 2.7.9 is to simply allow any TLS, and then after the handshake check the socket status and drop if it's not TLSv1.2. I'll check this. > Let's imagine NSA & friends manages to build a hidden channel that > would allow to identify the sender of a message.

There may be other ways to do it. Atheros designed the protocol in a way that it allows to synchronise (recover) in case it becomes desynchronised for some reason. This could, in theory, be used to inject additional data into the stream without the connection breaking (i.e. quasi-stealthily). The recovery isn't fully reliable in the old parser (it always skips as many characters are there were in the buffer), but in the new subsystem it is (it skips one byte until it's synced again). I think I should think more about how to prevent this from being misusable (perhaps only use the syncing when on UDP, and on TCP just drop the connection). > Anyway, the goal of my message was to warn you about this, so that > you could keep this issue in mind for the future...

Thank you for your reply. I think we should take into account only protocols that will be transmitted outside the LAN of a user. Protocols used localy don't matter. I will read the wiki and check the BM protocol to see in there are possibilities to hide hidden channels in it. I encourage you to read about the technics to design protocols that exclude creation of hidden channel. There must be a lot of litterature available on this topic (Ex: A protocol must not have unused fields, or padding bytes... ) I will let you know about my reading of BM's protocol. Kind regards, Stman.
