A cyberattack aimed airports of Europe, including Heathrow in London, Berlin and Brussels. Heathrow named the provider as Collins Aerospace company
The result of cyberattack was that automated systems were shut down, forcing the airports to serve passengers only by manual procedures.
In Brussels, the administration warned that the situation would have a “significant impact on the flight program”, with “inevitable delays and cancellations”. In Berlin, a statement warned of “longer waiting times in check-in” due to damage.

So far it is not known who is behind the attack. Heathrow has confirmed that it is facing problems related to a “technical issue” of a third provider, while passengers are required to control their flight with the airline before going to the airport.
Pictures on social media show endless queues in Heathrow.
