A man in his 40s has been arrested over an alleged cyber attack that caused disruption at Dublin, Cork, London Heathrow and other European airports in recent days.

The UK National Crime Agency (NCA) said the suspect was held in West Sussex on Tuesday on suspicion of Computer Misuse Act offences, and released on conditional bail.

Deputy director Paul Foster, head of the NCA’s National Cyber Crime Unit, said: “Although this arrest is a positive step, the investigation into this incident is in its early stages and remains ongoing.

“Cybercrime is a persistent global threat that continues to cause significant disruption to the UK.

“Alongside our partners here and overseas, the NCA is committed to reducing that threat in order to protect the British public.”

The alleged cyber attack affected Collins Aerospace and saw check-in and boarding systems disrupted at London Heathrow, Brussels and Berlin airports.

The airport disruptions that affected automated check-in systems were caused by a ransomware attack, the EU’s cyber security agency said yesterday, highlighting the growing risks of such attacks to critical infrastructure and industries.

Hackers knocked out automated check-in systems provided by Collins Aerospace, owned by RTX, affecting dozens of flights and thousands of passengers since Friday.

Collins Aerospace said yesterday that it was working with the affected airports and was in the final stages of completing updates to help restore full functionality.

“Airlines across Heathrow have implemented contingencies whilst their supplier Collins Aerospace works to resolve an issue with their airline check-in systems at airports across the world,” a Heathrow spokesperson said.

Dublin Airport was experiencing “minimal impact” and had some manual processes in place to combat the issue, a spokesperson said.
