North Korea Advances in Bioweapons?

Several globally recognized media outlets have reported this week that based on the U.S. release of the 2024 Adherence to and Compliance with Arms Control, Nonproliferation, and Disarmament Agreements and Commitments there is proof that North Korea has bioweapons that they didn't have before. I tracked down the actual report, which none of the news sources I saw actually linked to, but I still have no clue how they determined this and if its accurate or not.

What do you think?
