Emerging Threats: How eSIM Technology Is Vulnerable to Cybercriminals

The transition to eSIM technology has brought about a new era in mobile connectivity, but it also presents new challenges for cybersecurity. Unlike traditional physical SIM cards, eSIMs are chips embedded in the device that allow users to activate their service digitally by logging into an app or scanning a QR code. However, this modern technique does not provide complete protection against cybercriminals who are increasingly targeting users and attempting to access their accounts.

According to ESET, cybercriminals can exploit stolen or leaked credentials to gain access to users’ mobile accounts through social engineering, phishing, and other deceptive strategies. They often steal the QR code needed to activate the eSIM on their own device, effectively stealing the victim’s phone number and putting them at risk of financial losses and identity theft.

In 2023, FACCT reported an increase in SIM swapping attacks that took advantage of the transition to eSIM technology. Cybercriminals targeted financial institutions after cloning eSIMs, with over a hundred attempts recorded in a single institution alone. These attacks have serious consequences for security and privacy, including unauthorized access to personal accounts and potential financial losses.

To protect against phone number theft and other eSIM-related threats, ESET specialists recommend being cautious of phishing scams and suspicious contacts. They also recommend using strong passwords and two-factor authentication when possible to prevent unauthorized access to mobile accounts. Additionally, regularly updating software and firmware on mobile devices can help prevent vulnerabilities from being exploited by cybercriminals.

In conclusion, while eSIM technology offers many benefits for mobile connectivity, it also presents new challenges for cybersecurity. As such, it is important for users to be vigilant about protecting their personal information from cyberattacks that rely on stolen credentials or deceptive tactics.
