Report: Russia has access to UK visa processing

Sounds pretty straightforward to me, i.e. what any self-respecting security service would attempt to do, and Russia's FSB/GRU are more dedicated to their task than most. I would only be surprised if they were not doing any of the stuff they are alleged to be.

It is surely a relief when a small part of the hidden story surfaces occasionally.

Spies are spies. How many posters have never watched a James Bond movie?

I would be more worried about My Number, security cameras and internet search engine backdoors.

This should not be surprising

Any spy agency with enough resources can figure out to do this

People shouldn't underestimate the FSB/GRU's capabilities
