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 12: Ticket scammers target buyers and sellers

25.03.2025 - We regularly receive reports of ticket fraud, and with ticket sales for this year’s open-air season and the upcoming Eurovision Song Contest about to begin, the number of scams is likely to increase in the coming weeks. Scammers take advantage of the fact that demand for tickets outstrips supply: they resell tickets at inflated prices, sell counterfeit tickets and put fake ads on the internet. In an unusual and frequently reported scam, they try to lure their victims to a fake website. Exercise caution and don’t let scammers fool you.

Week 11: Chain phishing with Microsoft 365

18.03.2025 - Over the past week, we have seen a number of chain phishing attempts targeting Microsoft 365 accounts in organisations. The aim of these attacks is to gain access to accounts in order to steal sensitive data that can be used for further attacks. What makes this type of phishing scam unique is the way that it spreads, in a kind of chain reaction. As one of the most widely used platforms for communication and collaboration in offices, Microsoft 365 accounts are an interesting target for cybercriminals.
