"Although Microsoft's legal counsel managed to use US trademark law to seize and take down Trickbot's C2 infrastructure on the grounds that the malware occasionally impersonates the Windows operating system, UK criminal law doesn't help British companies take strong action against malware operators."
Good. I don't want companies to be able to misuse trademark law. If you want to take down malware networks (and you do), write a law that allows you to do that.
An 'imaginative' use of a law to do something good today, is an imaginative use of the law to do something bad tomorrow.
