SIM swapping attacks usually happen when a malicious hacker calls up a cell carrier impersonating a specific customer. This hacker would use information they found online, such as a customer’s name and date of birth, and then ask a customer support representative to transfer or “port out” that number to a different SIM card or carrier. As soon as that process completes, the person’s phone number will activate on a SIM card or phone controlled by the hacker, allowing them to make calls and send and receive text messages as if they were the person they just hacked.With your phone number, a hacker can start gaining access to your online accounts, and even trick automated systems into thinking they are you when calling customer service. A hijacked phone number can sometimes be used to access a company’s network as if they were that employee, allowing access to sensitive files and data. How do you protest yourself against SIM swapping ?
