“We face 45 billion intrusion attempts into our systems. Forty-five billion every day! And the worst thing is that this figure is twice as high as last year,” warned one of the main managers of JP Morgan from the Davos Forum. Since then, the bank has clarified that it is not necessarily the subject of 45 billion daily attacks, but that it must study 45 billion cybersecurity events every day.
“ This is the whole game of cybersecurity teams: being able to distinguish events that may seem trivial from events that herald the start of an attack. », explains Gérôme Billois, “cybersecurity” expert at the consultancy firm Wavestone. This involves, for example, when a person connects to the website to access their accounts, determining whether they are doing so at the correct time or from the same computer.
Banks and hackers are now engaged in a technological arms race, particularly around AI. “ Cybercriminals are very fond of artificial intelligence, because, as for us, it facilitates their activity, develops Gérôme Billois. This is what happened in Japan, where we saw a very sharp increase in cases of email fraud. Because now, thanks to artificial intelligence, cybercriminals can speak Japanese. We also see it in the use of fake videos which, thanks to artificial intelligence, make it possible to clone the image or voice. »
