RTX-owned Collins Aerospace is continuing to work with airports to get operations back to normal following a suspected cyber attack on Friday.

The incident, widely reported to be a ransomware attack, prevented customers from using automatic check-in at a number of Europe airports, including Heathrow, Berlin, Dublin and Brussels.

The BBC reported that ENISA, the European Union Agency for Cybersecurity, had confirmed that the type of ransomware had been identified and law enforcement agencies were investigating.

On Friday and over the weekend, airline staff at airports were forced to use manual or back-up systems to check customers in. Travellers were advised not to arrive at airports any earlier than would normally do for their flights.

By this morning (Monday September 22), there were ongoing delays at Berlin Brandenburg which was experiencing high demand due to the Berlin Marathon. Other airports impacted were getting back to normal.

A statement from the UK’s National Cyber Securitgy Centre spokesperson, said: “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.

“All organisations are urged to make use of the NCSC’s free guidance, services and tools to help reduce the chances of a cyber attack and bolster their resilience in the face of online threats.”

It was reported that the checking-in software system attacked was Muse. On Monday Collins confirmed that it was in the final stages of completing updates to the system following the cyber attack.
