As a result, all computer and registration systems became unusable, and all boarding and check-ins had to be handled the old-fashioned way: with pen and paper — leading to massive delays and numerous flight cancellations.
It soon became clear that not only Brussels, but also the airports of Berlin and London (Heathrow) were victims of this major attack. The term “ransomware” quickly emerged.
But what is ransomware? Explained in plain language: cybercriminals hack your computer or online systems and files and lock them with their own personal key. In other words, criminals install a new lock on your digital door or world, and you can no longer enter your online home or environment. If you want access again, that digital key is offered in exchange for an exorbitant amount of money (with cybercriminals usually opting for payment in cryptocurrencies).
Apart from a rock-solid security system, the “digitally kidnapped” victim has only two options left: either restore all data from a strong, fully up-to-date backup… or negotiate with the criminals to keep the (usually economic) damage as limited as possible.
