Rising Threat of SIM Swapping Attacks: How eSIM Technology Can Mitigate Risks
The telecommunications landscape is currently grappling with a significant crisis as SIM swapping attacks escalate at an alarming rate. In the United Kingdom, incidents surged by an astonishing 1,055% in 2024, rising from just 289 cases in 2023 to nearly 3,000 cases. This dramatic increase in telecommunications fraud has triggered urgent calls for enhanced security measures, with embedded SIM (eSIM) technology emerging as a viable solution to address this growing threat. As cybercriminals increasingly exploit the vulnerabilities of traditional SIM card systems, eSIM technology presents advanced security features that could substantially lower the success rate of these sophisticated attacks.
SIM swapping, also referred to as SIM hijacking, is a complex form of identity theft where attackers manipulate mobile carriers to transfer a victim’s phone number to a SIM card under their control. The attack typically follows a predictable pattern, beginning with cybercriminals gathering personal information about their targets through data breaches, social media reconnaissance, or phishing campaigns. Armed with details such as names, addresses, birthdates, and account security questions, attackers contact the victim’s mobile carrier, impersonating the legitimate customer and requesting a SIM transfer due to a “lost” or “damaged” device. The effectiveness of these attacks lies in their exploitation of SMS-based two-factor authentication (2FA) systems, which many organisations still rely on for security verification. Once attackers gain control of the victim’s phone number, they can intercept verification codes sent via SMS, allowing them to reset passwords and access banking accounts, cryptocurrency wallets, email services, and social media platforms. A study from Princeton University revealed that 80% of initial attempts at SIM swap fraud were successful across major U.S. wireless carriers, underscoring the widespread vulnerabilities in current authentication processes.
