Non-endorsed methods for accessing Tor hidden services
by Rishab Nithyanand 11 Sep '19

11 Sep '19

Hi Tor-Dev, I'm sending this message on behalf of Hammas, one of my PhD students at UIowa, who has been unable to get his emails past moderator approval. Hammas and I have been recently working on the implications of visiting the Tor hidden services through services not endorsed by Tor itself. The goal is to see if they're doing things that might deanonymize a user. Currently, we've only found a handful of Tor2Web websites and extensions. I have found injected HTMLs containing common trackers and tweaks in request headers which might cause serious privacy harm. We want to be more thorough in our study of this ecosystem and were hoping that you all might be aware of some non-Tor-endorsed extensions, websites, apps, or services that we should test. No matter how popular or obscure, please let me know! Thanks for your time and help! Best, Rishab

txtorcon 19.1.0
by meejah 10 Sep '19

10 Sep '19

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 I'm pleased to announce txtorcon 19.1.0, containing the following changes: * TorControlProtocol.on_disconnect is deprecated in favour of TorControlProtocol.when_disconnected * introduce non_anonymous_mode= kwarg in txtorcon.launch() enabling Tor options making Onion Services non-anonymous for the server (but they use a single hop instead of three to the Introduction Point so they're slightly faster). * add an API to listen to individual circuit and stream events (without subclassing anything). Can be used as decorators too. See e.g. TorState.on_circuit_new() * fixes to the CI setup to properly test Twisted versions You can download the release from PyPI or GitHub (or of course "pip install txtorcon"): https://pypi.python.org/pypi/txtorcon/19.1.0 https://github.com/meejah/txtorcon/releases/tag/v19.1.0 Releases are also available from the hidden service: http://timaq4ygg2iegci7.onion/txtorcon-19.1.0.tar.gz http://timaq4ygg2iegci7.onion/txtorcon-19.1.0.tar.gz.asc Or via a "version 3" service: http://fjblvrw2jrxnhtg67qpbzi45r7ofojaoo3orzykesly2j3c2m3htapid.onion/txtor… http://fjblvrw2jrxnhtg67qpbzi45r7ofojaoo3orzykesly2j3c2m3htapid.onion/txtor… You can verify the sha256sum of both by running the following 4 lines in a shell wherever you have the files downloaded: cat <<EOF | sha256sum --check 25d8e52c3eac45bb90ff958ca7cdd7674fb3284e3a50826a58ab7b9578b15ea5 dist/txtorcon-19.1.0.tar.gz e93aef50f339b537ed969a4d83a704a2870658bb49cdfa95495ba5a740548d32 dist/txtorcon-19.1.0-py2.py3-none-any.whl EOF thanks, meejah -----BEGIN PGP SIGNATURE----- iQFFBAEBCAAvFiEEnVor1WiOy4id680/wmAoAxKAaacFAl13SBcRHG1lZWphaEBt ZWVqYWguY2EACgkQwmAoAxKAaad/DwgA5r1XbcoPuzw2FSoDNwJNNzDSEFBT+W7Z Ej0Wp27B7KuUgCp83u08DWpCbuz1iOLiYveWtKil+CrXFpmxH2M9itF4pd3U71dt o/PfEnPy3OxWD1cka2bnuFO3HlmCs7LOy5KndRlWBSzqDXfqnwTLqNSHB94TMoh3 YEhyKmyo30DwLMeNdeayuJ18c24+U15kxt5+O7TPKSeNw88emizDMX3ZQFnuIUyJ 6ybZxIwkJxXLOlO+cqnLH26eSIFqHrvILTXPvZ3ie2cwNYOgNS4IpkmVUlrF41Zq xQgMdR1pzLWrEVMSPOYKicAnPW/drd8urwXMq5y2/dVuUhQmhHxBxg== =7R7N -----END PGP SIGNATURE-----

Hi, I love Tor Browser very much. So much that I just created a separate TB instance for local Intranet browsing. Everything is working fine but I just got a question related to links to other/external applications such as vmrc://192.168.76.224/?moid=36 It's from the VMware ESXi Webclient. I just set up a handler at 'Applications' in TBs Options and made it permanent: [TB_Applications.png] but it doesn't work :( the external application won't start :( Does TB have a protection against those links to external applications? If so. is there a way to turn it off? Thanks in advance Greetings LA_FORGE

Putting onion services behind a third-party TCP proxy
by Pop Chunhapanya 27 Aug '19

27 Aug '19

Hi all, When deploying an onion service, I noticed some problem that the ip address of my machine that runs tor daemon is exposed to the Tor network which is vulnerable to the DDoS attack if someone knows my ip address. So I'm thinking putting the tor daemon behind some third party TCP proxy that will protect me from this kind of DDoS attack. What do you think if I want to implement a feature that forward all the onion service traffic to the TCP proxy before going to the Tor network? The protocol that I'm thinking is TCP Proxy Protocol [1] [1] https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt

Enhanced Tor Browser sandboxing upstreaming
by procmem＠riseup.net 24 Aug '19

24 Aug '19

Hi. We aim to make enhanced sandboxing for Tor Browser widely available on Linux that's well maintained in the long term. We would appreciate it if TBB team provides the currently developed Apparmor and firejail profiles below from your repos and run unit testing and check/fix any breakages with updated browser versions. It turns out there is an advantage to stacking both Apparmor and Firejail. Firejail doesn’t offer nearly as good file path whitelisting as AppArmor. Firejail also can’t do many things AppArmor can such as managing ptrace or signals, yet firejail can use xpra to isolate Tor Browser's access to X, pulseaudio and the clipboard. The Firejail package included in Debian stable cannot keep pace with the needed changes as Tor Browser continues to change. Stacking is also a good defense in depth. If there’s a vulnerability in Firejail then AppArmor will still restrict the application or vice versa. Firejail provides a maintained official profile for Tor Browser [0]. We have a Apparmor profile that we've maintained for years [1].

TBB Memory Allocator choice fingerprint implications
by procmem＠riseup.net 21 Aug '19

21 Aug '19

Question for the Tor Browser experts. Do you know if it is possible to remotely fingerprint the browser based on the memory allocator it is using? (via JS or content rendering) We are thinking of switching Tor Browser to use the minimalist and security oriented hardened_malloc written by Daniel Micay. Thanks.
