This indicates an attempt to use Tor.
Tor (the Onion Router) is free proxy software designed for anonymous communication. Tor directs its traffic through a free, worldwide, volunteer network consisting of more than seven thousand relays to conceal a user's location and usage from anyone conducting network surveillance or traffic analysis. Using Tor makes it more difficult for Internet activity to be traced back to the user. Tor's use is intended to protect the personal privacy of users, as well as their freedom and ability to conduct confidential communication by preventing their Internet activities from being monitored.
