Could the Plot of Netflix's 'Zero Day' Occur IRL?

The article critiques the Netflix series 'Zero Day' for portraying an unrealistic, simultaneous nationwide cyberattack spread via mobile phones, while acknowledging it raises important real-world issues. Cybersecurity experts argue that although a mass, perfectly coordinated attack is unlikely due to heterogeneous technology stacks and detection challenges, credible threats include targeted strikes on single high-impact systems (air traffic, energy, water, hospitals) and supply-chain compromises or vendor cloud pivots that can affect multiple organizations; the piece emphasizes complexity, vendor consolidation risks, and OT safety isolation as key factors limiting such an event.
