A cyber attack on RTX's Muse software has crippled check-in systems at major European airports including London Heathrow, Brussels, Berlin, and Dublin for three straight days. The software handles passenger check-ins, boarding passes, and baggage tagging across multiple airlines. Airlines were forced to resort to pen-and-paper check-ins as the digital systems remained offline. Heathrow reported that most flights continued operating despite delays, while Brussels Airport directly called it a "cyber attack." Security experts warn these supply chain attacks are becoming more frequent in aviation, exploiting shared systems that serve multiple airlines simultaneously. The incident highlights the industry's vulnerability when critical third-party platforms fail. **Source:** [Infosecurity Magazine](https://www.infosecurity-magazine.com/news/airport-chaos-third-day-supply/)
