The European Union Security Agency says criminals use a ransom to cause chaos in airports all over the world.

Many of the most crowded airports in Europe in the past few days have spent an attempt to restore normal operations, after an electronic attack on Friday has disrupted automatic check -up programs and ascending to climb.

The European Union Agency for Cyber ​​Security, ENISA, BBC on Monday that the harmful program was used to calm automatic check -in systems.

“The type of ransom programs has been determined,” the agency said in a statement.

The BBC has witnessed contacts with internal crises from employees inside Heathrow Airport, which urges airlines to continue to use manual solutions to climb and verify passengers while continuing recovery.

Heathrow said on Sunday that he was still working to solve the problem, and apologized to customers who faced the delay of travel.

He stressed that “the vast majority of flights continued to work,” and urged passengers to verify their journey before traveling to the airport.

The BBC understands about half of the airlines that fly from Heathrow online in the form by Sunday – including British Airways, which has been a backup system since Saturday.

The attack was discovered against Collins Aerospace, the American software maker, on Friday night and has been disrupted at several airports on Saturday.

While this fell dramatically in Berlin and London Heathrow by Sunday, the delay and the abolition of flying remained.

Meanwhile, a Berlin airport spokesman told some airlines that are still handing passengers manually and had no indication of the period when the power outages will continue.

It is understood that infiltrators behind the attack targeted a common examination program called Muse.

Collens Aerospace did not explain what happened or told the audience how time it would take to solve things. The company still indicates it as an “electronic accident”.

In a statement on Monday morning, the program provider said that in the final stages of completing the necessary programs updates.

The internal note that was sent to Heathrow employees, which BBC sees, says more than a thousand computers may be “damaged” and most of the work to return them online should be done personally and not remotely.

The memorandum also says that Collins rebuilt its systems and restarted only to realize that the infiltrators were still inside the system.

In a separate advice for airlines, Collins told the employees not to turn off computers or log out of Muse if log in.

BBC called Collins to comment on the information in this memo.
