Anti-censorship team monthly report: July 2019
by Philipp Winter 05 Aug '19

05 Aug '19

Tor dev meeting =============== * Many anti-censorship team members attended Tor's developer meeting. Here are the meeting notes of all censorship-related sessions: <https://trac.torproject.org/projects/tor/wiki/org/teams/AntiCensorshipTeam#…> * We talked to OONI and asked if they could measure the availability of STUN servers for us. This would help with learning where snowflake is blocked: <https://github.com/ooni/probe/issues/875> * Started working on a "censorship table" that encodes what's necessary to get Tor to work in a given country (or autonomous system). Ultimately, Tor Browser should to use this table to help its users connect to the network while minimising user interaction: <https://bugs.torproject.org/28531> * Created a ticket for an easy-to-use Tor bridge meta Debian package: <https://bugs.torproject.org/31153> We hope to be done with this before our "set up new bridges" outreach campaign. Snowflake ========= * Deployed a proxy-go instance that uses the pion WebRTC library: <https://bugs.torproject.org/28942> We're evaluating if pion could replace libwebrtc for us. * Started working on the web extension "infinite loop bug" that currently affects Firefox: <https://bugs.torproject.org/31100> * Google's "Safe" Browsing system blocked snowflake's infrastructure domains *.bamsoftware.com. This is a false positive that was apparently caused by an educational article: <https://www.bamsoftware.com/hacks/zipbomb/> We migrated to a new domain: <https://bugs.torproject.org/31250#comment:13> * Fixed <https://bugs.torproject.org/27385> (<https://snowflake.torproject.org/embed> is confusing). * Started adding localisation to user-facing snowflake components: <https://bugs.torproject.org/30310> * Progress on easier-to-see snowflake icons in Firefox's dark mode: <https://bugs.torproject.org/31170> * Revised snowflake's project page: <https://snowflake.torproject.org> Bridge operators ================ * Worked with bridge operators who had troubles getting obfs4 to work. Pluggable transports ==================== * Started fixing a number of issues in our PT 1.0 spec. Here is our canonical list of issues: <https://bugs.torproject.org/29285#comment:5> Hopefully, there will be a way to merge these fixes with the PT 2.0 spec. Here's the in-progress feature branch: <https://dip.torproject.org/phw/torspec/tree/feature/29285> * Added in-progress wiki page on retiring pluggable transports: <https://trac.torproject.org/projects/tor/wiki/doc/PluggableTransports/Guide…> BridgeDB ======== * Deployed in-progress BridgeDB metrics feature branch which will give us insight into how BridgeDB is used: <https://bugs.torproject.org/9316> Found and fixed numerous bugs and eventually published first insights into BridgeDB metrics: <https://lists.torproject.org/pipermail/tor-dev/2019-July/013953.html> * Resurrected an old ticket to expose BridgeDB's assignments file again. This would allow bridge operators to see what bucket their bridge is in: <https://bugs.torproject.org/29480> Miscellaneous ============= * Reviewed a Tor Research Safety Board submission. * Wrote a summary of the NDSS'17 paper "Dissecting Tor Bridges": <https://lists.torproject.org/pipermail/anti-censorship-team/2019-July/00002…> * Filed ticket to have a single Tor instance support, say, more than one obfs4 instance: <https://bugs.torproject.org/31228> * Summarised the MASQUE circumvention protocol: <https://lists.torproject.org/pipermail/anti-censorship-team/2019-July/00002…> * Cecylia attended the Citizen Lab's Summer Institute 2019 and PETS 2019. * Philipp will attend the OTF summit in Taiwan, and probably also potential pre and post events.

Smashing all the bugs
by Stephanie A. Whited 01 Aug '19

01 Aug '19

** *Hello Tor! * * Today we launched our Bug Smash Fund. Through the month of August, all donations the Tor Project receives will be marked to help us smash bugs and respond rapidly to critical security issues. Many of you have experienced why we need such a fund: this kind of work is not usually covered by sponsors or grants, so we have to divert time and funds when these kind of things happen. And we know that they will happen. So this month is an opportunity to help us prepare for smashing the bugs ahead. If you’re able to make a donation, you can do so at https://donate.torproject.org We’re reaching out to community members, press, and influencers to spread the word, and we could use your help spreading the word, too. If you are on Twitter, you can help by sharing the blog post[1], writing a tweet using one of the graphics Antonela made (which you can find on the blog and our tweets) and using the hashtag #TorBugSmash, or just by liking or RTing our posts[2] or any other positive mentions. Talking about the fund IRL with someone close to you works great, too. If you feel comfortable, writing a post that mentions your involvement can have more impact than one without. You could write something like: “Bugs happen. I’ve worked on fixing them with @torproject, and we know there will be more. You can help us be prepared for what bugs may come by making a donation this month. All donations will go towards smashing bugs. #TorBugSmash https://donate.torproject.org” As always, I’ll be watching for posts from the Tor community to engage with and support. If there’s anything related to this campaign or our work in general that I’ve missed or would be relevant for us to share, please let me know. I’m also happy to talk over something you’re considering posting if you want feedback. You can DM @torproject or me personally @walnutwordsalad, send me an email, or ping me on IRC (stephw). Cheers! Steph [1] https://blog.torproject.org/tors-bug-smash-fund-help-tor-smash-all-bugs [2] https://twitter.com/torproject/status/1156910864391262208 * -- Stephanie A.

PSA: flood attack against OpenPGP certificates underway
by Antoine Beaupré 30 Jul '19

30 Jul '19

Hi, Since the Tor project uses OpenPGP and GnuPG extensively in its operations, I figured it was important to let the community know of an ongoing attack against the keyserver infrastructure and GnuPG. The longer story is available on dkg's blog here: https://dkg.fifthhorseman.net/blog/openpgp-certificate-flooding.html ... but a summary is that at least two prominent OpenPGP users have seen their public key flooded with thousands of signatures, to the point where their keys are now completely unusable. I recommend you consider taking the following immediate actions, either: 1. in the short term, disable automated key refreshes on your keyring (either through Parcimonie or manual scripts calling `gpg --refresh` in some other way), or; 2. switch to the new keys.openpgp.org keyserver, by setting the following in your `gpg.conf`: keyserver hkps://keys.openpgp.org/ The first action should only be used in the short term, to allow you to evaluate your options. It might mitigate the problem (unless you somehow allow the nasty keys to enter your keyring some other way), but it will mean you will not be aware of the precious revocation certificates users post when their key is compromised, so it's not an acceptable solution in any way. The second action has been tested as mitigating the problem, but has several downsides as well: a. it does not store UIDs unless they are verified and asked for explicitly (workaround: keys can be shipped in-band with Autocrypt or found through other mechanisms like WKD, Web Key Discovery) b. it does not store UID signatures at all, which will impact the web of trust (workaround: same as point a, and you should send signed keys by email anyways to verify ownership of the UID, using tools like caff, pius, gnome-keysign or monkeysign) c. GnuPG cannot read refresh keys from keys.openpgp.org (workaround: use the custom patch shipped in Debian experimental, see Debian bug #930665) d. it does not currently receive updates from the SKS pool (workaround: upload key updates to keys.openpgp.org directly as well as the SKS pool) Note that keys.openpgp.org has been seeded with the global SKS keyserver datastore, so it contains all the keys you would expect to be present on the latter, except they are sanitized to avoid this problem. I encourage users to: 1. upload their keys to the keys.openpgp.org keyserver 2. either switch to keys.openpgp.org by default or carefully review their key fetching configuration to make sure it is not vulnerable to this attack 3. review dkg's article and make sure your own keys are not affected by this problem If you have fetched an hostile key and GnuPG has become unusable, you can recover by deleting the key with: gpg --delete-key C4BC2DDB38CCE96485EBE9C2F20691179038E5C6 Note that this may take anywhere from 20 minutes to an hour. And then fetch dkg's key via WKD: gpg --locate-keys dkg(a)fifthhorseman.net or his website, <https://dkg.fifthhorseman.net/dkg-openpgp.key>. The other known key affected by this problem is Robert J, Hansen's key, with the fingerprint "CC11BE7CBBED77B120F37B011DCBDC01B44427C7". As far as I know, torproject.org infrastructure has not been affected in any way by this attack. We carefully monitor keys we allow in our keyring which should be sufficient to mitigate this attack. A. PS: to check if your key is affected *without* importing it into your keyring, you can use the following command: FINGERPRINT=0x8DC901CE64146C048AD50FBB792152527B75921E # for example mine KEYSERVER="http://pool.sks-keyservers.net/" URL="$KEYSERVER/pks/lookup?op=get&search=$FINGERPRINT&options=mr&fingerprint=on&exact=on" curl -sSL "$URL"| gpg --list-packets | grep -c '^:signature packet:' This counts the number of signatures on your key. A reasonable number is less or around a thousand. dkg's key has now around 55 000 signatures on his key, which (naturally) causes some trouble in all OpenPGP implementations. -- Antoine Beaupré torproject.org system administration
