Calls on behalf of a supposed NCSC employee
The NCSC has received reports of cases in which someone claiming to be an employee of the National Cyber Security Centre calls and asks to verify a supposedly suspicious bank transaction. The NCSC does not verify bank transactions and does not contact citizens unsolicited by telephone. Hang up immediately if you receive such a call and do not respond to any requests made by the fraudsters.

Week 50: Recall with financial consequences

16.12.2025 - Last week, the National Cyber Security Centre (NCSC) received an increasing number of reports about a scam that has been observed for some time. In this case, the victim is not pressured to click on a link, as is usually the case. Instead, under the pretext of an alleged suspicious transaction, they are asked to call back a telephone number. However, anyone who dials the number will not be connected to customer service, but directly to the fraudsters' call centre.

Report on the influence of artificial intelligence in cybersecurity

12.12.2025 - The Federal Council has examined how artificial intelligence (AI) is influencing cybersecurity and whether the National Cyberstrategy (NCS) can keep pace with rapid developments in AI. In a report on the opportunities and risks of AI systems in cybersecurity, commissioned in response to postulate 23.3861 from Gerhard Andrey and approved on 12 December, the Federal Council concludes that while AI acts as a catalyst for existing trends in cybersecurity, it does not change the fundamentals. AI projects will now be identified more clearly in the NCS to ensure transparency and allow for more focused control.
