Fraudsters often illegally manipulate their calling line identifier (CLI) to make their calls or SMS appear coming from a number which their victims trust, while the call is really made from another number or even from abroad. Cullen International’s new research looks at measures adopted by European telecoms regulators to fight such spoofing practices.
Out of 13 selected European countries, six adopted a do-not-originate registry collecting numbers that can never be used for outgoing calls.
In the Czech Republic, Ireland, Poland, Sweden, and the UK, telecoms operators must block incoming international calls that have a national CLI. France is the only country studied that adopted the STIR/SHAKEN protocol.
