Heathrow Hack Chaos: Why Your Holiday Is Now at the Mercy of Cyber Gangs

If you thought airport delays were just limited to security queues, overbooked flights, or someone taking too long at duty free, think again.

Heathrow was among several major European airports hit this weekend by a cyber-attack that targeted the very software designed to keep things running smoothly.

On Saturday, passengers faced long lines and flight delays after what Heathrow diplomatically described as a “technical issue” affecting electronic check-in and baggage systems. The victims? Collins Aerospace’s Muse software – the program that allows different airlines to share check-in desks and boarding gates.

Brussels Airport confirmed that a cyber-attack on Friday night forced staff to check in passengers manually – picture handwritten luggage tags and boarding passes called in over the phone – while Berlin Brandenburg Airport admitted to longer waiting times.

Passengers across Europe are dealing with cyber-induced delays.

RTX, the parent company of Collins Aerospace, said it was “aware of a cyber-related disruption” at “select airports” and was scrambling to resolve the problem. “The impact is limited to electronic customer check-in and baggage drop and can be mitigated with manual check-in operations,” the company explained.

British Airways managed to glide through the chaos thanks to a back-up system, but most other airlines at Heathrow weren’t so lucky. Dublin and Cork airports also reported “minor impact” from the attack. Heathrow insisted additional staff had been dispatched to help ease the disruption.

The fallout was significant. According to flight tracker FlightAware, hundreds of flights were delayed across Saturday. Eurocontrol, Europe’s combined aviation safety organisation, even asked operators to cancel half of their flight schedules between 04:00 GMT on Saturday and 02:00 on Monday.

The UK’s National Cyber Security Centre confirmed: “We are working with Collins Aerospace and affected UK airports, alongside Department for Transport and law enforcement colleagues, to fully understand the impact of an incident.” Meanwhile, the European Commission said there were no signs yet of a “widespread or severe attack,” though the investigation remains ongoing.

But here’s the bigger picture: the aviation industry’s growing reliance on digital systems makes it vulnerable in ways that feel straight out of a Netflix thriller. Analysts were quick to point out the risks. And while accusations that the Kremlin was behind the attack are currently unfounded, it is true that many major hacks in recent years have been carried out by well-organised cyber gangs whose goal is less geopolitics, more pay day.

British Airways lands smoothly as Europe battles a cyber-attack grounding check-in systems.

These extortion groups routinely make hundreds of millions of dollars a year, often by using ransomware to steal data, freeze systems, and demand ransoms in bitcoin. Some experts suggested this could be ransomware, but they note that both state-sponsored actors and freelance cybercriminals are known to use the tactic. Collins Aerospace has yet to confirm the nature of the hack.

As ever, Russia looms large in the cybercrime conversation. Many gangs are thought to operate out of the region, though plenty of arrests have been made elsewhere. In fact, British and American teenagers have recently been accused of major cyber-attacks on Las Vegas casinos, M&S, Co-op and Transport for London.

That hasn’t stopped speculation. Liberal Democrats MP Calum Miller pressed the government for answers, warning that “the government needs to urgently establish if Vladimir Putin is now attacking our cyber systems” and referencing reports of Russian warplanes entering Estonian airspace.

For now, we’re left with delayed flights, frazzled passengers, and a sobering reminder: in a world where your boarding pass lives in your phone and your luggage relies on an algorithm, cyber-attacks don’t just target companies – they ground people.
