Can eSim be hacked? The truth about eSIM

The security feature always plays a crucial role in the decision-making process when using a sim. Unlike traditional SIM cards, eSIMs cannot be physically swapped, reducing the risk of someone removing your eSIM and replacing it with another. However, does this mean eSIMs are completely immune to hacking? 

In this article, we will provide an in-depth answer to the question, “Can eSim be hacked?”, and an explanation for different cases. Moreover, there are some effective tips for you to protect your eSIM. Let’s continue reading!

Can eSIM be hacked?

eSIMs can still be hacked though they offer a higher level of protection than traditional physical SIMs as they can’t be stolen independently of the device. Nevertheless, several potential security risks still exist.

   1. SIM swap attacks

Regarding eSIMs, the danger of SIM swapping depends on how secure the mobile providers’ safety measures are. Hackers might try to convince carriers to switch the eSIM to another device, giving them unauthorized access to the victim’s calls and texts. This lets attackers grab one-time passcodes (OTPs) for online accounts, potentially leading to unauthorized access to the victim’s personal info and money. 

   2. Lost or stolen phones

Unlike regular SIM cards that can be physically swapped or stolen, eSIMs are built into the phone and can’t be removed. This creates a security risk, as hackers could exploit the eSIM if they get hold of the lost or stolen device.

   3. Remote code execution and supply chain attack

Remote code execution attacks let hackers run harmful code on a device from afar. Supply chain attacks target software developers and suppliers to access source codes, building processes, or updating mechanisms. While these attacks can be tricky to pull off, they pose a serious risk to the security of eSIMs and the devices using them.

How to protect your eSIM?

The previous section has addressed the question “Can eSIM be hacked?”. Even though eSIMs offer improved security, you should stay informed some following tips to prevent a bad situation:

• Keep devices and software up-to-date to address security vulnerabilities promptly.
• Utilize strong passwords and biometric authentication for enhanced device and eSIM security.
• Choose reputable carriers and device manufacturers with advanced security measures.
• Exercise caution against phishing and social engineering attacks; avoid clicking on suspicious links.
• Refrain from sharing personal information with unknown sources to prevent unauthorized access.
• Enable remote wipe and tracking features to protect data and locate the device if lost or stolen.

FAQs

   1. Is eSIM a security risk?

While eSIMs are designed to be secure, they can still be hacked. Some potential risks include remote code execution and supply chain attacks. These attacks could allow hackers to get sensitive information or take control of a device. 

   2. Does eSIM help in theft?

Yes, eSIMs can help prevent theft. Compared to regular SIM cards, eSIMs can’t be easily removed or swapped, making it harder for thieves to use the device or access personal information. 

Additionally, eSIMs can work with tracking features like Find My iPhone to locate a lost or stolen device. Users can enhance security by disabling Control Center and Siri from the lock screen and using eSIM exclusively. 

   3. Is eSIM encrypted?

Indeed, eSIMs are stored in a secure element (SE) on compatible devices, adding another layer of protection. The Trusted Execution Environment (TEE) further isolates the eSIM from the main system, providing a trusted environment. Despite these measures, eSIMs are not hack-proof, so keeping devices updated and using strong authentication methods is crucial.

Wrap up

So, if your friend asks, “Can eSIM be hacked?”, your answer should be yes, but it depends. The combination of encryption, remote provisioning security, and advanced authentication mechanisms fortifies eSIMs, making them a secure choice for users. However, there are still some cases in which hackers can steal your data. 

Therefore, being aware of some tips to protect your eSIM is important. Moreover, if you find this article helpful, please like and share it!
