Hacking

Hacking is the act of gaining unauthorised access to data banks and computer terminals.

Mickey Smith was skilled at this, hacking into John Lumic's Cybus Industries(TV: The Age of Steel) and also hacked into UNIT with the Ninth Doctor's help to launch a missile on 10 Downing Street. (TV: World War Three)

The Doctor was also a skilled hacker, demonstrating prestigious skill with computers on multiple occasions, particularly during his eleventh incarnation. (TV: The Eleventh Hour, The Bells of Saint John) The Twelfth Doctor also hacked the database on a Mondasian colony ship, rapidly redefining the definition of humanity for the Cyberman aboard to foil The Master's plans. Nardole was also a proficient hacker, hacking into the same colony ship's fuel lines to remotely detonate them. (TV: The Doctor Falls)
