I'm refreshing my social RSS feeds - who are blue teamers you follow?

With the new year, I'm looking to refresh my current list of folks I follow on Twitter/LinkedIn/Mastodon. In part of my research, every "who to follow" list are the same year after year regurgitating the same top headlines as everyone else on their Twitter feeds.

I'm particularly interested in advanced threat intel feeds, ransomware, and DFIR with some actionable insights. Open to newsletters that cover these topics as well.
