Agent name is "unknown". What's that about?
After the Anomaly in Los Angeles there are now Dark XM Portals spawning. They start as Level 1 but will spread and grow if left alone for too long. If you zoom in (or maybe out) a bit more the Red resonator symbols should appear. Or if you have a Key or the Deeplink for use in-app.
Hacking the portal will deplete 100% of your XM bar. Destroying the portal will drop keys and other items.
