This is how to protect yourself.<\/strong><\/p>\n<p>Telephone users have become used to a caller&rsquo;s number always being displayed for every call they receive. This is a longstanding myth: If a Swiss number is displayed for a call, this call originates in Switzerland and should certainly be considered trustworthy. Many people are not aware though that a number can easily be faked.<\/p>\n<p>Unlike Switzerland, where telephone companies are regulated by BAKOM, users of some foreign, non-regulated telephone networks can transmit any caller number they like. And you can also call into the Swiss landline network this way. All numbers, even if they have potentially been manipulated by an attacker, are passed on unchecked and displayed on your telephone display. The use of faked Swiss telephone numbers is a common practice used by criminals to build up trust in users. In addition, there are also some call centres with Swiss numbers actually operating abroad (source: <span class=\"glossaryLink\"  aria-describedby=\"tt\"  data-cmtooltip=\"&lt;div class=glossaryItemTitle&gt;National Cyber Security Centre (NCSC)&lt;\/div&gt;&lt;div class=glossaryItemBody&gt;The National Cyber Security Centre (NCSC) is the competence centre of the Federation for cyber security and hence the first port of call for businesses, administration, educational institutions and the population for any questions involving cyber security.
