No actualitzeu l'ordinador mentre estigueu amb una WiFi no coneguda
Si en connectar a una WiFi es mostra un missatge indicant que hi ha una actualització disponible per al sistema operatiu o una aplicació… sospiteu. Pel que indica un avís del FBI sembla ser una nova via per a la distribució de malware:
Recently, there have been instances of travelers' laptops being infected with malicious software while using hotel Internet connections. In these instances, the traveler was attempting to setup the hotel room Internet connection and was presented with a pop-up window notifying the user to update a widely-used software product. If the user clicked to accept and install the update, malicious software was installed on the laptop. The pop-up window appeared to be offering a routine update to a legitimate software product for which updates are frequently available.
