UK Arrests Suspect in Ransomware Attack That Disrupted Major European Airports

UK authorities arrested a man in his forties on Wednesday in connection with a ransomware attack that crippled check-in systems at major European airports. The suspect, charged under the UK’s Computer Misuse Act, has been released on conditional bail. The National Crime Agency's cyber unit, led by Paul Foster, is still gathering evidence and collaborating with international partners.

The attack targeted MUSE, a check-in software managed by US-based Collins Aerospace, freezing kiosks, bag-drop stations, and boarding infrastructure. Airports in London, Berlin, and Brussels were forced to operate manually, leading to flight cancellations and prolonged delays. Brussels Airport remains partially affected, advising passengers to check in online while systems recover.

The disruption highlights vulnerabilities in critical infrastructure and the escalating threat of ransomware. While no cryptocurrency was directly involved, the incident underscores the need for robust cybersecurity measures across industries.
