iOS seems to be leaking OCSP outside of Onion Browser
UPDATE, JUNE 15 2019: See advisory note & summary about this leak:
2019-178: sites with EV HTTPS certificates leak information via OCSP

Original GitHub issue:

Onion Browser on iOS is leaking data about some visited sites (both onion services and clearnet hosted servers). This happens because the browser checks for certificate revocations with OCSPv1 over non tor transport.

OCSP requests and responses made by Onion Browser goes via regular network, and since these are HTTP requests, any party with enough access to network can sniff it and identify the domains user is visiting.

Steps to reproduce

Consider a scenario where user is connected to an evil access point running tcpdump, and tries visiting “www.nytimes3xbfgragh.onion” in Onion Browser.

As you can see, the OCSP request is going via non TOR transport in HTTP and we can dump and Identify the domain.

We were also able to reproduce it for other OCSPv1 services - we tested

https://www.grindr.com

https://check.torproject.org

https://nytimes.com

https://flixbus.com/

We can also provide the packet dumps if you need.

Decoding an OCSP response =========================

Since the request payload is small OCSP spec allows it to be encoded in request URI. We got the http requests from browser on regular transport from tcpdump.

for e.g, this is the one from nytimes onion service. [Full request URI: http://ocsp.digicert.com/MFYwVKADAgEAME0wSzBJMAkGBSsOAwIaBQAEFEn0vYoYv3YGmMXeQC1oO3Fq5OaGBBQ901Cl1qCt7vNKYApl0yHU%2BPjWDwIQATXM5lnIy5Cdngkc9hmitg%3D%3D]

Reversing the encodings and parsing with ocsptool from gnuTLS.

echo MFYwVKADAgEAME0wSzBJMAkGBSsOAwIaBQAEFEn0vYoYv3YGmMXeQC1oO3Fq5OaGBBQ901Cl1qCt7vNKYApl0yHU%2BPjWDwIQATXM5lnIy5Cdngkc9hmitg%3D%3D | python -c "import sys, urllib.parse as ul; print(ul.unquote(sys.stdin.read()));" | base64 -d | ocsptool -i OCSP Request Information: Version: 1 Request List: Certificate ID: Hash Algorithm: SHA1 Issuer Name Hash: 49f4bd8a18bf760698c5de402d683b716ae4e686 Issuer Key Hash: 3dd350a5d6a0adeef34a600a65d321d4f8f8d60f Serial Number: 0135cce659c8cb909d9e091cf619a2b6

Looking this serial up in cert logs, you can see this is an OCSP request for nytimes onion services.

[1.X][2.X] Connection occasionally times out and does not recover → app becomes unable to load sites

Workaround: Force quit app (tap home to quit app, double-tap home, hold down on app icon in tray, and "delete" app) and then restart app.

Hard to recreate issue when running app for more than a few minutes.

Seems to happen regardless of if app has gone into background or if network has gone up/down. (In fact, app does send HUP to Tor in those circumstances, causing Tor to reload & build new connections.) #3 would help (and is related), but this is a more specific issue than that.

Connecting to Linkedin SSL error

Connecting to https://linkedin.com gives an SSL error (see screenshot). It works with desktop Tor browser, so i suppose it's not a Linkedin issue?

I tried to reduce security levels to 1 and also downgrade TLS in the settings, but nothing helped.

Onion Browser 2.0 may be leaking DNS requests
When using Onion Browser 2.0, I'm seeing that non-onion domains are appearing in my DNS' log (using pi-hole). When using the Tor Browser on Mac, those same domains aren't appearing.

Environment & Steps: iPhone X, iOS 11.2.2

Connect to my VPN (passes through a pi-hole)

Visit a non-Onion URL using Onion Browser 2.0

Notice that the site and the calls from that site are appearing in the pi-hole log

[2.X] Prompt for automatic use of bridges after 15 seconds

Possible new feature:

After 15 seconds of stalled initialization, automatically prompt user to try to use bridges (using obfs4 by default?)

Cuts out step where user has to wait and get frustrated that app isn't working, and then go into the bridge prompt and then have to figure out what to do.

Finalize security level language
Is it:

Insecure / Moderate / Secure

or

Low / Moderate / Maximum

The website currently shows the 2nd, versus the App shows the 1st option.

Should we match Tor Browser?

Standard / Safer / Safest?

There is concern that our "Standard" on Tor Browser is not equivalent

Let's find a way to survey, review, wordsmith what we need.

Examine why tor is opening many (20+) circuits; is this correct behavior?

Hi, we noticed the BBC logo (and other logos) on the landing page of Onion Browser (iphone SE, iOS: 16.2) do not appear.

Toolbar Blues

The bottom toolbar required to access tabs hides itself and there’s no way to get it back except to scroll way back to the top of an often very long forum thread. On the Dread site and I assume others, the browser lacks any inertial scrolling so scrolling is always 1:1 and thus laborious. Since I can’t set a font size either, some forum threads collapse into one a few characters as they become repeatedly indented. That makes scrolling back to the top just to close a tab very frustrating. Then the tabs gallery page lacks any useful highlighting to indicate which the current tab is, so I must check the tab title to find it. Really I’d just like an option for normal tabs instead of a silly gallery view. And that I can keep it from ever being hidden. Like a normal browser!

[feat] Clear Cache

Was working with a user that could not access an onion site that was known to be online. A blank white page came up, suggesting perhaps a caching issue? Lowered security settings to lowest, rebooted phone, reinstalled app, turned off VPN, and the problem persisted. Another iOS Tor Browser showed the onionsite as live on the same device. Trying another known live onionsite produced an all black screen.

Perhaps a "Clear Cache" button would be useful, although I'm not sure if it is the root of this particular issue

Thanks for your hard work :)

v1.6.0(Aug 8, 2016)
See onionbrowser.com and onionbrowser.com/security for official announcements and notes.

Changes:

See changelog for full details.

iObfs: Onion Browser now supports "pluggable transports" like obfs4 and meek, which improve connection support in locations that try to block Tor. For more info about iObfs (an iOS framework build of obfs4proxy), please visit: https://github.com/mtigas/iObfs (Special thanks to the Onion Browser beta testers for their feedback on this new feature. Extra special thanks to The Guardian Project for supporting work on iObfs!)

"One-click" bridge UI: Onion Browser now comes with built-in bridges for obfs4, meek-amazon, and meek-azure -- same the official Tor Browser Bundle and Orbot.

User-agent spoofing strings updated to the most recent browser versions.

Tor updated to 0.2.8.6, the first stable release in the 0.2.8 series. This version contains several performance and security improvements. https://blog.torproject.org/blog/tor-0286-released https://gitweb.torproject.org/tor.git/tree/ChangeLog?h=tor-0.2.8.5-rc

OpenSSL updated to 1.0.2h. https://www.openssl.org/news/secadv/20160503.txt https://openssl.org/news/changelog.html

Minimum required iOS version is now iOS 8.2.

Changes:

Minimum required iOS version is now iOS 8.0 (was iOS 6.1). Users running iOS 8.0 and 8.1 will be warned about HTTPS insecurity in these older versions (due to FREAK exploit). iOS 8.2 will be required by the end of 2015.

Update HTTP errors. The "HTTPS Connection Failed" error was displaying in situations where the error had nothing to do with SSL failure.

Allow navigating to "about:blank" and allow setting the homepage to that URL. (#62)

Update bridge handling to make it difficult to enter in an unsupported bridge type, such as "obfs4" or "scramblesuit" via text entry or the QR Code scanner. (Prevents a situation where a user ends up with an "unusable" Onion Browser.)

Tor updated to 0.2.6.5-rc. https://gitweb.torproject.org/tor.git/plain/ReleaseNotes?h=release-0.2.6

OpenSSL updated to 1.0.2d. https://openssl.org/news/changelog.html

Tor updated to 0.2.6.5-rc. https://gitweb.torproject.org/tor.git/tree/ChangeLog?h=tor-0.2.6.5-rc
OpenSSL updated to 1.0.2a. https://openssl.org/news/secadv_20150319.txt https://openssl.org/news/openssl-1.0.2-notes.html
Redesigned "Connecting..." prompt when opening the app.

Verification:

You can check that your version of Onion Browser matches a known copy of the app. This is helpful for safety reasons, if you are not confident that your copy of Onion Browser has been tampered with.

You'll need to have this version of Onion Browser (1.5.12) downloaded and available in iTunes. Go into iTunes and make sure that Onion Browser appears in the "My Apps" tab. Since this is the most recent version of Onion Browser, ensure that the app is updated. (If it has an "Update" flag, you can right-click the app and select "Update App" to download 1.5.12.)

If you don't have Onion Browser on your computer, you can retrieve this version by syncing your iPhone/iPad to your computer or by searching for Onion Browser in iTunes with the same Apple account that you used to buy it on your iPhone/iPad.

If you get a hash that's different than cc31dad8ec3aa4f72b1de09557d5840b2039c585328098973b3cb1a7ad3205d521c95a21288443dd8eef86028800db0895b1e47b20e131054947685c5161fc44, please report it in this thread immediately, or e-mail me.

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

If you have installed Onion Browser via the App Store, you can
double-check the authenticity of your copy of Onion Browser by doing
something like the following and ensuring that the resultant SHA512
hash is identical. 

Sync your phone (& sync the apps over to your computer) or download
Onion Browser via the App Store in iTunes on your computer. Then:

$ mkdir /tmp/ob1512
$ cd /tmp/ob1512
$ unzip -o "$HOME/Music/iTunes/iTunes Media/Mobile Applications/Onion Browser 1.5.12.ipa"
$ rm -fr "Payload/OnionBrowser.app/SC_Info"
$ find Payload -type f -print0 | xargs -0 shasum -a512 | shasum -a512
cc31dad8ec3aa4f72b1de09557d5840b2039c585328098973b3cb1a7ad3205d521c95a21288443dd8eef86028800db0895b1e47b20e131054947685c5161fc44  -

It'll tell you that your copy of the Onion Browser app package is
the same as everyone else's. (But of course that doesn't help if
there's fishiness in Xcode or in the App Store submission process.)

Per [1][2], although the App Store-hosted ".ipa" bundle of the app
changes from user-to-user (because the ".ipa" zip file contains
user-specific SC_Info), the remainder of the app contents should be
the same from user to user. See [3] & [4] for further work on this.
