Highlights eSIM technology enables digital SIM swapping, exposing users to new fraud risks. Attackers use stolen credentials to port victims' phone numbers to their devices. Cybersecurity experts recommend using complex passwords and two-factor authentication. Increased eSIM adoption calls for enhanced security measures against cyber fraud. The introduction of embedded Subscriber Identity Modules (eSIMs) has heralded a new era of convenience and connectivity. These digital SIM cards, stored directly on a device's chip, offer a seamless way to maintain cellular service without the physical constraints of traditional SIM cards. However, this advancement has not come without its pitfalls. Cybercriminals, ever adaptive, have found ways to exploit eSIM technology to commit fraud, posing a significant threat to user security and privacy. The Mechanics of eSIM Swapping Scams SIM Swappers are using eSIMs on compatible phones to pull off their SIM swap rip-offs. eSIM technology, while revolutionary, has inadvertently provided cyber criminals with a new vector for attack. As per a press release by Russian outlet Facct, by exploiting the digital nature of eSIM provisioning, attackers can hijack a victim's phone number and, by extension, gain unauthorized access to their personal and financial accounts. This type of attack, known as SIM swapping, is not new, but the method of execution has evolved with the advent of eSIMs. Traditionally, SIM swappers used social engineering tactics or insider assistance to port a target's phone number to a new device. However, with increased security measures put in place by mobile carriers, attackers have turned their attention to the vulnerabilities inherent in eSIM technology. By obtaining a victim's mobile account credentials through phishing, brute force attacks, or data leaks, they can initiate a number of porting requests to a device under their control. "Having gained access to the victim's mobile phone number, cybercriminals can obtain access codes and two-factor authentication to various services, including banks and messengers, opening up a mass of opportunities for criminals to implement fraudulent schemes," said F.A.C.C.T. analyst Dmitry Dudkov. This process involves generating a QR code that, once scanned, reprograms the eSIM, effectively transferring the victim's phone number to the attacker's device. Countermeasures and Recommendations Embedded Subscriber Identity Module that is embedded inside your phone and doesn't come out The shift to eSIM technology, while convenient, necessitates heightened vigilance and enhanced security measures to protect against these sophisticated attacks. Cybersecurity experts advocate for the adoption of complex, unique passwords for cellular service accounts and the activation of two-factor authentication wherever possible. For accounts holding sensitive information, such as banking or cryptocurrency wallets, additional layers of security, including physical security keys or authenticator apps, are recommended. FAQs What is eSIM fraud? eSIM fraud occurs when cybercriminals hijack a person's phone number by exploiting the digital SIM technology (eSIM), allowing them to gain unauthorized access to the victim's personal and financial accounts. How do attackers carry out eSIM swapping? Attackers perform eSIM swapping by acquiring a victim's mobile account credentials through methods like phishing, then generate a QR code to transfer the phone number to a device they control.

Scammers can use your social media profiles to gather information on you that may help them impersonate you when they’re trying to close a SIM swap scam. What are the Signs that you’re the victim of a SIM swap? 1. You can’t make calls or send texts Getting errors when trying to send texts or make calls? The first sign that you could be a victim of SIM swapping is when your phone calls and text messages aren’t going through. This likely means fraudsters have deactivated your SIM card and are using your phone number. 2. You’re notified of activity elsewhere You’ll know you’re a victim if your phone provider notifies you that your SIM card or phone number has been activated on another device. 3. You’re unable to access accounts If your login credentials no longer work for accounts like your bank and credit card accounts, it’s likely that scammers have changed your passwords and usernames, maybe after having taken over your phone number. Contact your bank and other organizations immediately to let them know. 4. You find transactions you don’t remember making If you’re checking your online credit card statement and you notice several transactions that you don’t remember making, you might be the victim of a SIM swap scam. This is a sign that criminals have accessed your credit card number and used it to make unauthorized purchases. They might have done this by first stealing your phone number and using the information sent to it to access your account. How can you protect against SIM swap scams? Fortunately, there are ways in which you, and your service providers, can help protect against becoming a victim of SIM swap fraud. Online behavior: Beware of phishing emails and other ways attackers may try to access your personal data to help them convince your bank or cell phone carrier that they are you. Don’t click on links in email messages from people you don’t know. And remember, yourbank, cable provider, credit card company, or other service providers won’t ask for your personal or financial information through an email message. Account security: Boost your cellphone’s account security with a unique, strong password and strong security questions and answers that only you know. PIN codes: If your phone carrier allows you to set a separate passcode or PIN for your communications, consider doing it. It could provide an additional layer of protection. IDs: Don’t build your security and identity authentication solely around your phone number. This includes text messaging (SMS), which is not encrypted. Authentication apps: You can use an authentication app such as Google Authenticator, which gives you two-factor authentication but ties to your physical device rather than your phone number. Bank and mobile carrier alerts: See if your banks and mobile carrier can combine efforts, sharing their knowledge of SIM swap activity, and implementing user alerts along with additional checks when SIM cards are reissued, for instance. Behavioral analysis technology: Banks can use technology that analyzes customer behavior to help them discover compromised devices, warning them not to send SMS passwords. Call-backs: Some organizations call customers back to make sure they are who they say they are — and to catch identity thieves.
