We recently rolled out a vishing campaign in KnowBe4 to a client’s mobile, and when the call came in, it showed up as ‘Potential Fraud Caller’ on his phone.
He is using a Samsung Galaxy S9, on the Vodafone Ireland network. I also use the Vodafone Ireland network, but with a different Android phone (OnePlus) but saw no such message when I had tested vishing to my own number, nor did my colleagues who also use Samsungs.
KnowBe4 support say there is nothing they can do currently - some phones or security apps will make a good guess that the number calling is a potential fraud and label it as such for the enduser.
Have any of you experienced this when vishing clients, and have a workaround in place?
Thanks in advance for any help,
