My Broadband's Jan Vermeulen says the 'sim swap scam' sounds like a rejigged version of an older con that did the rounds.
It sounds like a variant of the old 'tech support scam'.— Jan Vermeulen, senior journalist at MyBroadband.co.za
He describes how someone will phone you with a credible sounding problem that you may be experiencing either on your computer, phone, VCR or TV.
And then says 'I will fix it for you, all you have to do is x, y, z - usually giving them privileged access to your device, or giving them some kind of private information that they can then hijack to exploit your identity.— Jan Vermeulen, senior journalist at MyBroadband.co.za
