From the ‘who’s really shocked?’ department.

It’s one of those stories that repeats through history to the shock of those who live through it. Police get better body armor, criminals get better bullets, and so on. It’s always a good idea to assume your opponent will take your technology and use it against you.

Pirates of centuries past used the ships, weapons, and other technology of those they targeted, and it’s not much different today. This is true whether you’re talking about piracy on the high seas or network security.
