European Airports Paralyzed by MUSE Software Ransomware Attack

A sophisticated ransomware attack has brought major European airports to a standstill, targeting the critical check-in systems that form the backbone of modern air travel operations. The coordinated assault on Collins Aerospace's MUSE software platform has exposed significant vulnerabilities in aviation infrastructure, prompting urgent security reviews across the industry.

The attack began in the early hours of Tuesday morning, when airport operators across Europe reported system failures affecting passenger processing. London Heathrow, Europe's busiest airport, was among the first to experience disruptions, followed quickly by Berlin Brandenburg and Brussels Airport. Within hours, the cascading effects had spread to multiple major hubs, creating one of the most significant aviation cybersecurity incidents in recent years.

Collins Aerospace's MUSE software is widely deployed across European airports, handling critical functions including passenger check-in, baggage handling, and flight management. The system's central role in airport operations made it an attractive target for cybercriminals seeking maximum disruption and financial gain.

European Union cybersecurity authorities confirmed the ransomware nature of the attack, noting that the perpetrators had encrypted critical systems and were demanding substantial payments for decryption keys. While specific ransom amounts remain undisclosed, security analysts familiar with the investigation suggest they run into millions of euros.

The attack methodology appears sophisticated, with initial analysis suggesting the attackers gained access through compromised credentials and then moved laterally through the network. Security researchers have identified similarities with known ransomware groups that specialize in critical infrastructure targeting, though no group has yet claimed responsibility.

Airport operators have been forced to implement emergency contingency plans, with staff processing passengers manually using paper-based systems. This has resulted in significant delays, with some airports reporting wait times exceeding three hours. Airlines have issued travel advisories warning passengers to expect disruptions and allow extra time for check-in procedures.

The incident has triggered emergency meetings at the highest levels of European aviation security. The European Union Aviation Safety Agency (EASA) is coordinating with national authorities and Collins Aerospace to contain the attack and restore normal operations. Cybersecurity teams from multiple countries are working to analyze the malware and develop remediation strategies.

This attack highlights the growing threat to critical transportation infrastructure from sophisticated cybercriminals. Aviation systems, particularly those handling passenger processing, have become increasingly interconnected and dependent on software platforms like MUSE. This interdependence creates single points of failure that can have cascading effects across multiple airports and airlines.

Industry experts note that the aviation sector has been increasingly targeted by ransomware groups in recent years, but this attack represents a significant escalation in both scale and impact. The targeting of core operational software rather than administrative systems demonstrates a strategic shift toward causing maximum operational disruption.

Collins Aerospace has mobilized its global cybersecurity response team and is working with customers to restore systems safely. The company emphasized that customer data protection remains a priority and that forensic analysis is underway to determine the full scope of the breach.

The recovery process faces significant challenges. Simply restoring from backups may not be sufficient if the attackers have compromised the integrity of the entire system. Security teams must ensure complete eradication of the malware before bringing systems back online to prevent re-infection.

This incident serves as a stark reminder of the vulnerabilities in critical infrastructure systems and the need for robust cybersecurity measures. It will likely accelerate existing efforts to enhance aviation cybersecurity standards and may prompt regulatory changes requiring more stringent security protocols for airport operational technology.

As the situation evolves, passengers are advised to check with their airlines for the latest information and prepare for continued disruptions in the coming days. The full impact on travel schedules and the timeline for complete recovery remain uncertain as cybersecurity teams work to contain the damage.
