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 16: Reusing old devices: great for the planet, but keep these tips in mind

22.04.2025 - Last week the NCSC received an unusual report from a person who had disposed of their broken laptop and was later contacted by someone from abroad claiming to have found their data on a newly bought laptop and have uploaded it to a cloud server. They asked if the previous owner still needed the data and wanted to download it, or if they should delete it. It’s a mystery how this data ended up in someone else’s possession. Could this be a blackmail attempt or a strategy to spread malware? The answer is surprising.
