Project Glasswing and the Claude Mythos Preview have caused an upheaval related to vulnerability discovery and exploit development. On Nexus, former NSA Director Adm. Michael S. Rogers introduces some nuance to the discussion. The nuance that isn’t being articulated enough, he says, is that Project Glasswing is largely a defensive effort that does more to level the playing field between threat actors and defenders than we may realize.

OT has a cybersecurity skills gap. Leading organizations, however, are responding by building cross-functional IT/OT security teams, investing in OT-specific training, creating hybrid cybersecurity roles, and leveraging managed OT security services to bridge immediate gaps. They are also prioritizing asset visibility, documentation, and standardized processes to reduce reliance on tribal knowledge.
