E-mails with malware in the name of debt collection agencies and health insurance companies

02.12.2024 - The NCSC is currently receiving numerous reports of e-mails that claim to come from a debt collection agency or a health insurance company. They concern an alleged claim or reminder. Do not click on the link, as this is an attempt to distribute malware to Windows users.

Caution: Fake letters on behalf of MeteoSwiss – Instead of a ‘Severe Weather Warning App’, malware is downloaded

14.11.2024 - Physical letters with MeteoSwiss as the sender are currently being sent out. The letters ask the recipients to download a new ‘Severe Weather Warning App’ via a QR code. However, malware is downloaded to the smartphone instead. This looks similar to the Alertswiss app from the Federal Office for Civil Protection on the smartphone's home screen.

Week 34: Phishing text messages about fake parcel notifications

26.08.2025 - Over the past week, the NCSC has seen a significant rise in reports of phishing text messages with fake parcel notifications. In this scam, attackers pose as Swiss Post or DPD in an attempt to steal sensitive information from people. Apple users are targeted particularly often. This week's review explains how to recognise these messages and protect yourself.

Week 33: Cybercriminals use social engineering to spread malware

19.08.2025 - Last week, we received two reports of cases where attackers tried to trick recipients into installing malware. These show just how much the methods have changed: Getting malware onto a computer is much harder today than it was a few years ago. Attackers are now increasingly relying on sophisticated social engineering to achieve their aims.
