The Treasury department is out with a statement saying that Yellen raised the matter of “malicious” cyber activity carried out by Chinese state-sponsored actors in said meeting. Adding that there was an unspecified amount of computers at the Treasury that had been compromised by Chinese hackers last month. That occurred after a breach of its contractor, BeyondTrust.
