Chinese couple charged with smuggling a biological pathogen into the U.S.

It was a post-doc student who wanted to continue his research at UMich on the fungus to develop ways to prevent blight. His peer-reviewed published research on the topic is available through google scholar: Google Scholar Link. He was wrong to try and sneak it in, but this looks like a dedicated scientific researcher making a bad decision - not an attempted terrorist attack.

The last of us 3?

The pathogen is a fungus that causes blight on wheat and barley crops. No idea what the plan was, but bringing that to the Midwest could have been bad if released.

Honestly? Chicken Little didn't scream as loudly as you have over this.
