A recent rise in SIM swapping attacks has raised concerns about the security of two-factor authentication (2FA). SIM swapping, a form of identity theft, involves hackers stealing a victim's phone number to gain access to their accounts. This method, also known as port-out hijacking, allows hackers to intercept calls and texts, including those used for 2FA, making it easier to breach accounts. Reports indicate that hackers have stolen significant amounts of money, with one case involving $19,000. The increase in these attacks highlights the need for improved security measures and awareness about the vulnerabilities of current authentication methods.
