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.

The NCSC provides weekly updates on current cyberincidents that have been reported.

Week 52: More focused, more intricate, more sophisticated – almost 65,000 reports submitted to the NCSC in 2025

30.12.2025 - In its final weekly review of the year, the NCSC typically reflects on the reports it has received over the past twelve months. This year, the NCSC received almost 65,000 reports of cyberincidents, which represents a significantly smaller increase than in previous years. Although reports concerning 'calls supposedly from the police' still dominated in 2025, more reports in this category were recorded in the first half of the year than in the second. This decline was offset by a substantial rise in the number of reports concerning 'online investment fraud'. Despite only a moderate increase in reporting volume, scams have become much more sophisticated.

Week 51: Alleged Christmas miracle – When fraudsters recover your lost funds

23.12.2025 - Christmas is considered a time of hope and reflection, and this is precisely what fraudsters who pose as alleged helpers are counting on. They tell victims who have lost money through online investment fraud, for example, the good news that these lost funds have 'reappeared'. But the miracle never happens. Instead of a refund, victims are presented with bills, and are pressured to pay various 'service fees' until it becomes clear that the promised refund will never materialise. This is how the promised Christmas miracle turns out to be fraud.
