Scammers are constantly on the lookout for new opportunities to exploit vulnerabilities and gain unauthorized access to sensitive information. One such trend that has recently come to light is the targeting of eSIM technology, posing a fresh challenge for mobile device users worldwide.
Reports from BleepingComputer shed light on scammers’ latest tactic: pilfering phone numbers by transferring them onto a new eSIM card. This marks a significant shift in their approach, presenting users with new risks and necessitating heightened vigilance.
But what exactly is an eSIM, and how are scammers exploiting it?
Embedded Subscriber Identity Modules (eSIMs) are digital counterparts of physical SIM cards, residing on the chip of mobile devices. Offering remote reprogramming capabilities, eSIMs enable users to activate and deactivate them through QR code scans provided by service providers. While convenient for users, this very feature has become a target for cybercriminals seeking to bypass security measures.
The modus operandi of these attackers has evolved in tandem with advancements in technology. So instead of relying solely on social engineering tactics or insider assistance, scammers now exploit vulnerabilities in mobile accounts using stolen credentials.
Once they gain access to a victim’s account, they initiate the process of transferring the phone number to a new device by generating QR codes within hijacked accounts, effectively taking control of the victim’s number.
The consequences of falling victim to such attacks can be severe. Once scammers gain control of a victim’s phone number, they can exploit it for various fraudulent activities, including unauthorized access to sensitive accounts and services, potentially leading to financial loss and identity theft.
So, how can mobile device users protect themselves from falling prey to eSIM scams?
First and foremost, it is crucial to adopt robust security practices. This includes using strong, unique passwords for all accounts and enabling two-factor authentication whenever possible. Additionally, users should consider implementing additional security measures, such as using physical security keys or authenticator apps, especially for critical accounts like banking and email.
