There are so many organisations that get compromised these days, it'd be overwhelming to post links to them all. But the Department of the Treasury getting hacked is a pretty big one. https://www.nytimes.com/2024/12/30/us/politics/china-hack-treasury.html

That second paragraph hits hard: "It was unclear from the Treasury’s limited first account of the episode exactly what the hackers were seeking. But senior officials with access to the intelligence on the breach said that it appeared to be entirely an espionage operation and not part of other Chinese efforts to insert malicious computer code into utility grids and water supply systems, giving them a capability to shut off critical American infrastructure."
