Thank you very much for the question.
If it's okay, I'll respond in English. It's just better for everybody.
It's very important to understand that, in fact, cyber-attacks are the greatest risk to space systems. Of the direct-ascent anti-satellite weapons that Michael Byers mentioned, there are only four countries that have demonstrated that capability. It's a highly unlikely kind of interference precisely because of the debris it creates and the risk that it creates to their own capabilities. Cyber-attacks and other forms of link segment interference, like jamming and sending a false spoofing signal, are happening every single day already.
In terms of the risk of a citizen becoming a vector in that, the risk is very low. We're not likely to accidentally interfere with that link, but we are at risk of losing out on the service when there are those cyber-attacks. Again, it's the example of Russia launching a cyber-attack on the U.S. Viasat satellite in 2022, deliberately. It had the desired effect of interfering with communications, not only for the Ukrainian forces but also for all Ukrainian citizens and for many citizens in neighbouring countries as well.
I think there needs to be a greater level of awareness of that. I advocate a lot for space literacy. I do a lot of executive education for the Australian government and, together with SSCL, for the Canadian government. There's a space fundamentals course that you all can take to get a greater understanding of what those risks are.
As individuals, there's probably not a lot we can do in terms of cyber-hygiene or protection, but there's a great deal we can do in terms of raising the understanding of the risks and of our uses of those space systems.
