Voice phishing, or vishing, is having a moment right now, with numerous active campaigns across the world that are ensnaring even savvy victims who might seem likely to know better, defrauding them in some cases of millions of dollars.
With scammers typically operating outside the geographic locations that they target, their outbound calls may initially appear to originate from an international or Internet calling number. However, through the use of a SIM Box device, they can mask their calls, making them appear as if they are being made from a local mobile phone number.
"This technique can deceive unsuspecting individuals into believing the call is from a domestic source, thereby increasing the likelihood of the call being answered," he says.
SecretCalls is just one of nine vishing apps giving cybercriminals in South Korea the tools they need to conduct campaigns, the researchers have found. This indicates that multiple vishing groups are operating globally, highlighting the importance of remaining vigilant even to the most convincing scams, Ryu says. Educating employees about the trademark characteristics of the scams and the tactics that attackers typically use to try to fool victims is also crucial to avoiding compromise.
