This just in: China is not our friend.

Case in point: We learned Monday that a Chinese hacker, one "affiliated with the Chinese government" — which means the Chinese Communist Party (CCP) — has hacked the United States Treasury Department.

An actor affiliated with the Chinese government recently hacked the U.S. Treasury Department in a "major incident," officials announced on Monday.

In a letter obtained by FOX Business, the Treasury Department disclosed the incident to Senate Banking Committee leadership. Officials learned of the breach on Dec. 8.

The cybercriminal reportedly gained access to Treasury Department workstations and documents via a security key.

"Once Treasury was alerted by the service provider, we immediately contacted Cybersecurity and Infrastructure Security Agency (CISA) and have worked with law enforcement partners across the government to ascertain the impact of this incident," the spokesperson said.

What isn't mentioned is what, if any, questions have been raised with the Chinese government as to why a hacker "affiliated with" China was seeking access to the U.S. Treasury. It is belaboring the obvious to note how unlikely it is that this Chinese hacker acted on his or her own; this was likely done with at least the consent of the Chinese government, if not on the orders of the Chinese government.

The affected database has been taken down for the moment:

"The compromised BeyondTrust service has been taken offline and there is no evidence indicating the threat actor has continued access to Treasury systems or information."

The news came as the state-affiliated Chinese hackers continue an espionage campaign against the U.S. government. Last week, the White House said that Chinese officials accessed Americans' private texts and phone conversations through the targeting of a U.S. telecommunications company – the ninth telecom company to be affected by Chinese hacking.

Speaking to reporters, deputy national security adviser Anne Neuberger said that the government was planning further action in the coming weeks in response to the hacking campaign, but did not disclose specific details.

I should hope she didn't disclose any details, as it seems the efforts to uncover exactly how this happened are still ongoing. China's increasing bellicosity is not limited to hacking; they have assets on the ground in the United States, many having crossed into the country illegally through our porous, untended southern border. What's more, the Chinese are apparently dialing their military forces in as well.

Chinese hackers have apparently been probing the edges of the United States government databases for some time now. A Chinese hacking operation code-named Salt Typhoon has been implicated in the hacking of nine American telecommunications companies, gathering up private call records and communications; unnamed officials have indicated that "senior government officials and prominent political figures" have been among those whose communications were compromised. It seems unlikely that the Chinese Communist Party isn't behind this.

This is cyber warfare. What is it leading up to?

And, as we might expect:

FOX Business reached out to the Treasury Department for more information, but did not immediately hear back.

You don't say.
