A data breach refers to unauthorized access to an information system, service or device or unauthorized use of an application, such as an email account, by means of acquired access codes. Carrying out a data breach is a punishable offence as defined in the Criminal Code, and an attempted data breach is also punishable. Just accessing a system without authorisation meets the definition of an offence and does not require using the target of the breach or the data it contains.
