It is a strange world indeed were the crime of hacking i.e. accessing a computer system in order to get information (see definition below) does not actually cover that specific activity and where the prosecution authorities will need to rely on the broad wash-up wording of obtaining a “benefit” to get a prosecution under S249 to stick.

It is all the more perplexing when one considers that something as ephemeral as “electricity” is covered but not the data or information on the computer being hacked.
