-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Ok, let's try to find our what's going in here. I checksummed some files:
- ---- ++ The directory I found yesterday evening. https://www.torproject.org/dist/torbrowser/3.6.3/ - -> This was the old download directory for the Torbrowser v3.6.3 - -> Not accessible via web browser - -> There is no signature "torbrowser-install-3.6.3_en-US.exe.asc" in this directory. Files: https://www.torproject.org/dist/torbrowser/3.6.3/torbrowser-install-3.6.3_en-US.exe - -> Filesize 323 b. This file is a little bit too small to be the Torbrowser.

When you look at some subjects of yesterday "Third-parties tracking me on Tor" "TOR tried to take a snapshot of my screen" Perhaps somebody is trolling this list and tries to seed confusion.
