Right. Since Directory Protocol v2, statements made by a Directory
authority are believed by a Tor client "iff they were attested to by
more than half of the authorities", so an adversary needs to
compromise more than half of the Tor Directory authorities to be able
to lie effectively to Tor clients.

See dir-spec-v2.txt in the torspec Git repository¹ for details.
The "0.1. History" section of the (WIP) dir-spec.txt is a nice
introduction to how such matters are dealt with by Tor.
