To celebrate smashing 74 bugs last year with the Bug Smash Fund, we are running a special offer:

This week only (August 17-21), everyone who donates exactly $74 (must be $74!) will receive two mystery t-shirts + a pack of stickers from Tor.

In May and June 2020 we found and removed a group of Tor exit relays that were messing with exit traffic. They left almost all exit traffic alone, and we don't know whether any users were successfully attacked.
