Blackmail emails in circulation
The NCSC is currently receiving reports of emails in which blackmailers claim to be in possession of credit card details, driving licence details, social security numbers and other data. They threaten to sell this information on the dark web. The emails often appear to come from the recipient's own address. However, this is not the case. The sender address is fake. The email is a bluff. Ignore it and do not be intimidated.

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.

Cyberthreat level remains high – attacks becoming more targeted and complex

30.03.2026 - The semi-annual report published today by the National Cyber Security Centre (NCSC) outlines the relevant incidents and developments relating to cyberthreats against Switzerland and internationally in the second half of 2025. Alongside voluntary reports of cyber incidents, the report presents reportable cyberattacks against critical infrastructure for the first time. Such attacks have been mandatory reporting requirements since 1 April 2025. Although the number of voluntary reports has remained stable at a high level, the nature of these incidents is evolving and becoming more targeted. Effective protection requires close cooperation between government, businesses and society at both national and international levels.
