These days most people, including criminals, store a lot of personal data on their computers. CHERUB agents are often required to get hold of this information. If the information is hidden, password protected of encrypted, this may require a high degree of skill.

A computer hacking module has been included in the CHERUB basic training program since the late 1980s. All agents are taught hacking skills, enabling them to bypass simple passwords and find hidden or deleted data. More secure data, such as encrypted data, can usually be copied onto a portable hard disc drive or memory key and passed on to MI5, where specialists have a strong record of decoding even the most strongly encrypted information.
