Mr. Joseph Stephens:

There are national security issues resulting from some of the scam calls. I will make particular mention of a malware called FluBot, which had the potential to overload some of the networks because of how it was proliferating. If it got onto one person's phone, it went to everybody in his or her phone book and so on. We worked closely with the operators and the regulator so that the operators could take action by providing threat intelligence, blocking numbers and dealing with our international partners. The computer security incident response team, CSIRT, is a network across Europe that has been set up well. We are a part of that network which shares that type of intelligence so that we can proactively stamp out that activity.

We are working on the practical solutions to this.
