Hackers Hijack Phone Numbers by Porting to eSIM Cards to Bypass Security
-
SIM swappers are now hijacking phone numbers by porting them to eSIM cards, which are digital SIM cards stored on a device's chip. This allows them to bypass some protections.
-
eSIM cards are becoming more popular among phones and wearables because they don't require a physical SIM card slot.
-
Attackers are breaching mobile accounts with stolen credentials to generate QR codes that port the victim's number to the hacker's eSIM card.
-
By hijacking the phone number, hackers can access online banking and other services using two-factor authentication.
-
Defenses include using complex passwords, two-factor authentication for accounts, and physical security keys.
