I'll say a few words, and then I'll turn it over to my colleague, Mr. Finley, to colour that in a little bit.
It ranges. It goes from the person in the basement to a nation-state actor.
I think earlier, when we were discussing incidents and reporting, one of the distinctions that the CER drew was the difference between an attack on an information technology network—that is the network that provides your email and stores your documents and passwords—and then the operational technology network, which is the systems that are used to operate pipeline valves and other systems. To date, there has been no successful attack that we're aware of in Canada in the CER's regulated industry on an operational network. Within your information technology networks—the ones with passwords, etc.—yes, those have happened quite frequently.
Mr. Finley, did you want to colour that in a little bit?
