Is this thing really secure?

Oct 27 19:56 [raw]

Would a good Samaritan do me the favor of explaining the security of Bitmessage? I want something secure for international business operations. Are there other options to consider?

Oct 28 15:13 [raw]

If you have real security requirements you probably should consult with a professional, and probably the least biased place to inquire about a technology is among is user base. My opinion, which only a fool would take unqualified, I am happy to give you. Security consists of the "CIA Triad" , Confidentiality, Integrity, and Availability. Briefly, Confidentiality is the ability to prevent disclosure of sensative information, integrity is the ability to prevent unauthorized modification, and availability is the ability to access a resource when needed. Bitmessage is a new unproven technology with exteremely questionable availablity. Its a peer to peer network, that requires each node to receive all messages. Bitmessage probably has scaling issues, and if your 'international business' is of sufficient merit, you might hedge your business against the risk of bitmessage either becoming too popular and thus unavailable due too many messages, or dying off due to a lack of clients to make up the network. Further, bitmessage is a relatively new technology, indeed still in beta, without a lot of resources behind its development, and the long term development, and security of the client are an open question. For instance, recently a remote-code execution vulnerability was fixed, will future vulernabilities be discovered and fixed? For how long? The developer is an individual not an organization with long term resources. Finally, the condifentiality is also up for question. Bitmessage is based upon standard and modern cryptography, and in principal is secure. However, in principal and reality are very different things when it comes to cryptography. Cryptography is hard, and the standard advice is "don't write your own crypto". The bitmessage code hasn't undergone audit, is a realtively new technology. There may be no problem, then again, there may be. Security is all about having a threat model, and understanding your risks, and taking a security posture. Deploying a new tool to 'be secure' sounds awesome, but is the wrong way to think about security. You should consider what assets you have, who you are protecting them against, and what options you have to ensure the CIA triad. You may wish to communicate privately with your business partners, and desire that this communication be available to some margin, and secure to some margin against an attacker with control over the local network (IE. at a coffee shop) but not account for the ability for governments to find and exploit vulernabilities in software, or influence service providers to include backdoors. Optionswise you might consider: Skype, Gmail, Whatsapp, and BitMessage, You might find, that in this threat model, all of these things have little to distinguish themselves, except that bitmessage has an open question of its availability. Alternatively, your threat model might include pervassive mass serveilance, in which case your tolerance for propetary software or service providers like whatsapp, gmail, might be thin. You could choose to use bitmessage while accepting the risk that its client might contain vulnerabilities, or its cryptography may be poorly implemented, or, you could use a propetary e-mail provider and mitigate serveilance risk with a technology like PGP. One techonology you might consider is PGP + standard e-mail. This is a veristile, well tested technology that has been deployed for decades, and advocated publicaly by Snowden in seeking to escape US government serveilance in 2013. It allows you to use standard e-mail, that generally has good availability, and has a relatively low cost - e-mail can be as affordable as free. Ultimately, there are many different threat models and technologies out there, and is hard to advise for 'international business'. Specially, when most peoples 'need for security' is more about a kind of spy role play - my own included. My own thinking is that most 'international business' needs little to no security margin beyond what is afforded by traditional e-mail (over secure SMTP/IMAP) if you are seeking to prevent competitors from accessing your communications. If you are seeking to prevent governments from accessing your communications through targeted methods, or that you might face an Advanced Persistant Threat (APT), you probably would be a fool to use PyBitMessage if any asset of substantial value (say your freedom) depended on it. At any rate, asking here for advice surronding your assets is a bad idea.

You can post seriously obscene child pornography images here, nobody is able to find out who or where you are, and nobody can prevent you posting them.

Oct 29 13:44 [raw]

I would say that would be incredibly reckless, not to mention immoral, considering that this technology is beta, and just had a remote code execution vulnerability patched. Governments have used vulnerbilities in clients like tor browser before to deanonymoze people before.

Oct 29 15:27 [raw]

but that's not part of my business model

Oct 29 18:59 [raw]

Nor do they have even remotely the same threat model. For example, people post child pornography to the bitcoin block chain, and while it does ensure integrity, and may not be easy to censor, and possibly anonymous, it doesn't protect the confidentiality of materials posted. Just because a group of people is using some tool or method doesn't make it a great choice for you, unless your threat model is similiar.

illegal content dont prove security it could be provocation, aka part of the honeypot bitmessage is good at hiding the receiver of a message if the sender is already under surveillance his uploads can be identified via timing attacks by listening to CPU radiation from proof of work calculation see van eck phreaking would be nice to see a more silent POW variant maybe via tor-hidden http-to-bitmessage gateways with other means of flood limiting aka shifting the problem back to more centralization

If you are really worried about the security of BM then you would be better off not using it.

Nov 17 08:16 [raw]

When you are using bitmessage, you should always assume that NSA/GCHQ can identify you, but that no organisation below their level of expertise can. Just don't post any unlawful messages and you should be left alone by the NWO/Illuminati.

> by listening to CPU radiation from proof of work calculation your cpu radiation follows the power cord out into the electrical grid. how convenient. i saw the original tempest data that described how signals leak into the grid lines. they covered that shit up real fast and nobody ever heard about it again. if you have a 60khz phase on the line there's a lot of room in there for minute phase interruptions.

Nov 17 11:34 [raw]

if you are relly this worried about it, just take your computer off the grid. run it on solar or some shit and stop whining

Nov 17 12:30 [raw]

> take your computer off the grid ... and build a tempest safe room, good luck shielding magnetic waves ... and find a way to hide your metadata, like vuvuzela was trying or join your local secret service where they will prefer steganography, aka hiding in plain sight > i saw the original tempest data that described how signals leak into > the grid lines. they covered that shit up real fast and nobody ever > heard about it again. in honeypots we trust who is NSA targeting again? terrorists and whistleblowers? i feel i fit both labels ^^ but only in theory. they know me already, and it would be stupid, to even try to front them. living in stand by, waiting for never ...

In their Newspeak, everyone who uses an anonymous messaging system is a terrorist with something to hide and they are prime targets of all government agencies.

Nov 17 17:21 [raw]

either terrorist, or terrorist helper, aka sympathizer target of ALL agencies? oh yes ... they took my job / friends / family, even my welfare money ultimately driving me into 'suicide' still funny, cos my death is not my problem if my talent is not welcome in this world, then fuck this world * hits the opium pipe *
