Experts say that swapping SIM cards is on the rise as hackers try to gain access to a phone user’s finances, unbeknownst to those users.
SIM (subscriber identity module or subscriber identification module) cards are the small smart cards that contain information identifying a specific phone network that allows the user to use most functions on their device. Hackers are contacting a target’s cellphone carrier, answering simple security questions and swapping the phone number associated to a SIM card they control.
