The main topic may be a bit more heated and less aligned with typical discussions on HN, but as a DC resident and security/policy wonk I found the details of the breach of the Supreme Court's veil to be much more fascinating. Main topic is the leak of the draft opinion overturning Roe v. Wade. https://www.politico.com/news/2022/05/02/supreme-court-abort...
In terms of a breach, I don't believe I've seen anything like this. They seem to have figured out who leaked this. That person will have to live with their decision. I don't know how they will justify or rationalize it, but I don't fathom I would want to be them right now.
Insider threat is very commonly a breach/leak issue. People who have legitimate reason to have access can decide what to do afterwards. No magic DLP is ever stopping someone who has real access. You have to pat people down and wand them for metals and even look for concealed sd cards. It far more security than they are ever subjecting to these people. So the hole is open.
The only way to prevent a breach when the hole is open is to ensure there's no need to leak. If discussing or planning to repeal roe vs wade. The supreme court should be doing this all in public. It doesn't have to be all out news event or even live for that matter.
