Hacking

Hacking was 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) He was so skilled that he hid himself online to search for information about the Doctor, keeping himself hidden for a year. (TV: Aliens of London)

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 all the cameras on Earth, switching them off to discover which biochemicak research centre the monks were watching (TV: The Pyramid at the End of the World) and also hacked the database on a Mondasian colony ship, rapidly redefining the definition of humanity for the Cybermen aboard to foil 's plans. (TV: The Doctor Falls) Nardole, having dubbed himself the "computer guy", (TV: World Enough and Time) was also a proficient hacker, hacking into the same colony ship's fuel lines to remotely detonate them. (TV: The Doctor Falls)

Clara Oswald and her counterparts were skilled hackers. Oswin Oswald managed to hack into the Daleks Pathweb and deleted all memory of the Doctor within seconds, a feat the Doctor himself admitted he couldn't do despite trying for years. (TV: Asylum of the Daleks) Clara herself gained capable hacking skills, using them to hack into the Shard's computer networks to disrupt their work and take pictures of them using their web cameras. (TV: The Bells of Saint John)
