UK police have arrested a man in connection with a cyberattack that disrupted check-in systems across major European airports, marking one of the most disruptive ransomware incidents in recent years.
UK Police Arrest Man Over Hack Investigation
According to the National Crime Agency (NCA), the suspect, a man in his 40s, was arrested on Tuesday under the Computer Misuse Act.
He has since been released on conditional bail as the investigation continues.
The cyberattack, which targeted Collins Aerospace, a subsidiary of RTX Corporation, left airlines and airport operators scrambling to restore operations.
Collins Aerospace supplies key technology systems to airports and airlines across Europe, making the hack’s impact widespread and immediate.
“This arrest is a positive step, but the investigation into this incident is still in its early stages and remains ongoing,” said Paul Foster, Deputy Director of the NCA.
The ransomware strike caused check-in and boarding system outages at several airports, including London’s Heathrow, Berlin Brandenburg, and other hubs across the continent.
Thousands of passengers were left stranded in long queues, while airlines faced mounting delays and cancellations.
Berlin airport operator BER confirmed that its systems may remain compromised for several more days, delaying the return to full operational capacity.
The disruption has also affected smaller regional airports, creating a ripple effect across European air travel.
At Heathrow Airport, passengers described scenes of “chaos and confusion” as staff were forced to manually process boarding passes.
“It felt like everything had gone back 20 years. The systems just froze, and nobody knew how long it would last,” one traveler told reporters.
So far, no cybercriminal group has claimed responsibility for the attack. Ransomware gangs typically use dark web platforms to publicize breaches and pressure victims by leaking stolen data.
However, security experts monitoring these channels have not identified any group linked to the Collins Aerospace hack.
The NCA has declined to disclose technical details, but analysts note that ransomware gangs often target industries with high operational risks, such as aviation, because disruptions can quickly escalate into multimillion-pound losses.
“Targeting airports raises the stakes dramatically,” explained cybersecurity analyst Robert Jenkins. “It’s not just about financial damage; it’s about public safety and confidence in critical infrastructure.”
The Collins Aerospace hack was not an isolated case.
Jaguar Land Rover, Britain’s largest car manufacturer and owned by Tata Motors, announced earlier this week that it would extend a factory shutdown until October 1 following a separate cyberattack earlier this month.
The shutdown has rippled through its supply chain, leaving smaller auto-parts suppliers struggling to stay afloat.
Analysts warn that such attacks highlight Europe’s growing vulnerability to cybercrime.
Ransomware attacks typically involve hackers infiltrating company systems, encrypting sensitive data, and demanding payment — often in cryptocurrency — to restore access. Criminals frequently threaten to leak sensitive files if victims refuse to comply.
While many gangs operate from outside Europe, law enforcement agencies have intensified cooperation across borders to disrupt cybercriminal networks.
However, the secrecy and anonymity of the dark web make attribution difficult.
In response to the latest wave of attacks, European governments are ramping up cybersecurity protocols.
The European Union recently signed a contract with French IT giant Atos to provide enhanced cybersecurity services to EU institutions.
Meanwhile, Britain’s Civil Aviation Authority has urged airports to conduct urgent security audits to identify vulnerabilities.
“The aviation sector is a high-value target, and the lessons from this incident must be taken seriously,” the agency said in a statement.
Cybersecurity experts argue that the incident is a stark reminder of the fragility of modern infrastructure.
As airports, factories, and utilities become increasingly digitized, the potential for hackers to cause large-scale disruption grows.
“Every part of our economy now depends on interconnected systems,” noted Dr. Hannah Ellis, a lecturer in cybersecurity at King’s College London.
“When hackers target those systems, the consequences ripple far beyond the immediate victim.”
With the suspect released on bail, investigators are working to trace digital footprints that could reveal whether the hack was the work of an individual, a criminal syndicate, or a state-linked group.
As Europe struggles to restore systems and reassure travelers, the UK police arrest man over hack serves both as progress in the investigation and as a warning that cyber threats to critical infrastructure are escalating.
For now, passengers continue to face uncertainty, airlines count their losses, and law enforcement agencies across Europe brace for the possibility of further cyberattacks.
