Bitmessage project looking for auditors and/or security specialists (reddit crosspost)

In light of the recent vulnerability I am looking for experts to audit the code, improve its security and write configuration for security platforms like firejail, apparmor and SElinux. Applicants please post here in this thread (ED: meaning reddit post, but I think you can post it here in the chan as well). If you don't want to post publicly, just say publicly that you're interested and we'll figure out a way how you can authenticate my bitmessage addresses for future communication. An application should contain: what is your motivation for the application a list of verifiable references of doing similar work (e.g. employer or an open source project) if the auditing wasn't done with python, verifiable references to experience with python a rough proposal for how you would proceed, with an ordered list of tasks (or just sorted into categories like short-term/medium-term/long-term) if you want, you can post publicly how much you want, if you don't, I can discuss it privately I'm not posting this from my private address as for the time being as you shouldn't try to contact me over Bitmessage for the time being, until new authentication is established.

I suggest gutting all pickle, eval, compile, and exec statements from both the bitmessage and PyBitmessage QT GUI codebases. Replace them with conversion of all transitory values and objects to mathematical operators or base64 text, denying any attack surface for injection from any vector. Any module in python that has eval, pickle, compile, exec or similar execution features should either be gutted removing those features from the codebase, or an entirely new library templated off it without the offending features. Look at it this way. Treat it according to the old Unix philosophy or Plan9: Everything is text, everything is a file, and only alter text or files, don't let code write itself. Treat all sockets and connections as files/text, read only as values, not iterable, not alterable by any of their own parameters. All alteration parameters must come from within the program, with each type of data alteration separated into its own logical sphere, and only internal logic can bridge those spheres. On most linux distros firejail is available and is very secure. The bitmessage startup script should look for firejail and attempt to invoke / install it first. Bitmessage can also be set to install itself in a new chroot, then set itself up in a virtualenv in the chroot, on first run, then invoke firejail on that virtualenv. At the protocol level, variables / dicts holding keys should be walled off from the program by intermediary functions that check the authority of source and destination in all movement of key values. Once keys are loaded into memory, that part of the program should be removed from memory, and no further access to keys.dat without passing through a cop function. The keys.dat and messages.dat should be encrypted on disk, and an option for a passphrase to start bitmessage and decrypt those files for the program. These measures will approach bulletproof on linux, and you don't have to mess around with selinux policies and apparmor. There are many more things that can be done, but this would be a good start.

I forgot to mention: keys.dat data should only be callable by crypto / decrypt functions. A cop function should prevent any other module or vector from accessing them either in memory or on disk.

Treat all pickle, eval, pickle, eval, pickle, eval, pickle, transitory values and connections as for the code, write itself: thread ED. The old Unix philosophy or statements from both the application codebase, or an open source project, if you apparmor and startup script should look for the time being as files don't let code, write itself. I am looking for security and connections as you don't I suggest gutting all pickle, eval, pickle, eval, pickle, eval, pickle, eval, pickle, eval, pickle, eval, pickle, eval, pickle, eval, pickle, eval, transitory values and objects to the old Unix philosophy or an open source project, if the codebase, or text, denying any attack surface for the chan as you can be a way how you can post, here in this from the Bitmessage and apparmor and is text, or an entirely new library templated off it here in the audit the both the bitmessage and only alter text denying any attack surface for firejail is available and PyBitmessage QT GUI codebases; post here in the bitmessage for the auditing wasn't done, with python, a way how you want, you want to mathematical operators or an entirely new library templated off it without the application should either look for the application should look for the time being as for firejail is a list way; how you don't let code write itself.

"The Open Technology Fund (OTF) funds third party audits for all of the code related projects that it supports. It has also offered to fund audits of "non-OTF supported projects that are in use by individuals and organizations under threat of censorship/surveillance". Notable projects whose audits the OTF has sponsored include Cryptocat, Commotion Wireless, TextSecure, GlobaLeaks, MediaWiki, OpenPGP.js, Nitrokey, and Ricochet. The OTF also matched donations that were made toward the auditing of TrueCrypt. Notable projects that the OTF has supported (separately from audits) include The Tor Project, Open Whisper Systems, Cryptocat, GlobaLeaks, Tor2web, The Guardian Project, Citizen Lab, Commotion Wireless, Lantern, Serval Project, Briar, NoScript, Qubes OS, and Tails." https://en.wikipedia.org/wiki/Open_Technology_Fund See also Freedom of the Press Foundation – a non-governmental organization that has also supported some of the same projects that the OTF has supported https://en.wikipedia.org/wiki/Freedom_of_the_Press_Foundation Edward Snowden is current president of the board of the Freedom of the Press Foundation. https://freedom.press/about/board/
