Countering SIM-Swapping

In this study, we give an overview of how SIM-Swapping attacks work, list measures that providers can take to mitigate the attack and make recommendations for policy makers and authorities in the telecom sector and other sectors. Security of electronic communications networks and services does not only translate to minimising the risk of service deterioration or outage, but also to protecting individual customers, for example against fraud, such as SIM swapping attacks
