As an alumnus, having gained a UHI degree after I left corporate IT, may I add that that's true but doesn't tell the whole tale. UHI has the largest student body of all Scottish universities - over 40 000 students, and has campuses* from Shetland and Orkney to Perth and Argyll, in addition to the fabulous main purpose built campus in Inverness. It has an enviable reputation for research although it is the youngest Scottish Uni. Don't discount that research portfolio as being one potential target.
It feels like an unenviable coming-of-age for UHI to be the target of this attack, and I wish their IT staff well.
*. While as a collegiate institution there are numerous campuses spread across an area larger than Belgium (I don't know what that is in Waleses - you can do the ElReg conversion yourself) it also caters for individuals too distant from main campuses. I did my entire degree from the north west of Scotland, where the nearest campus was across the Minch in Stornoway on the island of Lewis, but I had fellow students who were joining VC lectures years before COVID made it popular, from Canada and elsewhere in the world.
