New Cybersecurity Risks Arise with eSIM Technology: Protecting Yourself from Phone Number Theft

Cybercriminals are increasingly targeting users of eSIM technology, which is a chip embedded in the device that allows for digital activation of mobile services. Unlike traditional physical SIM cards, eSIMs do not require a physical card to be inserted into the phone. Instead, users can activate their service by logging into an app or scanning a QR code. However, this modern technique does not prevent cybercriminals from attempting to steal user accounts and personal information.

According to cybersecurity company ESET, cybercriminals can access users’ mobile accounts using stolen or leaked credentials. These cybercriminals often use social engineering, phishing, and other deceptive strategies to break into user accounts and obtain the QR code needed to activate the eSIM on their own device, effectively stealing the victim’s phone number. In 2023, Russian cybersecurity company FACCT reported an increase in SIM swapping as eSIM technology became more popular. Cybercriminals targeted financial institutions after cloning eSIMs and were able to access customers’ personal accounts with over a hundred attempts recorded in a single institution.

Being a victim of eSIM swapping can have serious consequences for security and privacy. Some threats include unauthorized access to personal accounts and potential financial losses. To protect against phone number theft, ESET specialists recommend being cautious of phishing scams and suspicious contacts. They also suggest enabling two-factor authentication on mobile accounts and regularly monitoring account activity for any suspicious behavior.

In conclusion, while eSIM technology offers many benefits such as convenience and elimination of physical SIM cards, it also poses new challenges for security and privacy. It is important for users to be aware of these risks and take proactive steps to protect themselves from cyber threats related to eSIM technology.
