Have you ever faced a situation where your phone suddenly disconnects from the network for no reason? Then you must have found multiple emails to reset your password. If this is the case, then you may be prone to SIM swapping attacks. It is a cyber attack that intends to steal information, hack bank accounts, and take over online lives.
However, you do not need to worry about it anymore, as some smart steps can help you prevent yourself from SIM swapping attacks like a digital pro. Let’s delve into what the attack is and how you can protect yourself.
What is a SIM Swapping Attack?
SIM swapping attacks, also known as SIM hijacking, are a type of cybercrime that tricks your mobile network into transferring your mobile number to a cybercriminal’s SIM card or mobile device. If they have control over your mobile number, they can eventually intercept SMS-based two-factor authentication codes and access your personal details and activities like bank accounts, social media, email, crypto wallets, and, unfortunately, your entire life. It is similar to providing your home keys to a thief.
Growing Threat and Mitigating Actions
There is a growing threat of SIM swapping attacks. In response to this, US carriers are taking key steps. Following the increasing cases of SIM-based fraudulence, AT&T, Verizon, T-Mobile, and Mint Mobile are taking steps to protect the SIMs of their users. They have launched an option to make you decide when and how your SIM can work.
Let’s understand in detail what the carriers are offering:
Verizon
Verizon offers you two key features:
- SIM Protection: This allows users to block unauthorized SIM swaps or eSIM transfers
- Number Lock: Through this, you can prevent your mobile number from being ported to another network
When to use these features:
- Go to the My Verizon app or site, and you will receive a notification once you turn on these settings
- Do not forget to enable if you make any big changes
T-Mobile
T-Mobile overtook its SIM protection system against the SIM swapping attacks this year and now offers:
- SIM protection option– Turn on or off the per-line or account-wide through the T-life app or web page
- In-store photo ID requirement- Required to remove the SIM lock
- Port-out protection– Prevents unauthorized number transfers
- This update provides control in the user’s hand to prevent SIM swapping attacks.
Mint Mobile
Mint Mobile is also offering protection against SIM Swapping attacks now:
- Number Lock– It stops SIM activation or changes of mobile number
- You can disable the SIM activation through a one-time password sent to your mobile number
- This feature can be activated through the Mint app or the online portal.
AT&T
AT&T has made efforts to:
- Wireless Account Lock- Prevents unauthorized SIM changes
- Transfer PIN- Need to port the number to another network
- MyAT&T app supports the feature of Wireless account lock
How to Detect SIM Swap Attacks?
There are some signs that can help you detect the SMI swap attacks earlier.
Suspicious email or messages– When you find messages or calls asking for your private information, you should quickly take action.
Continuous calls and messages- If you are getting continuous calls and messages to turn off your device, you must be alert about the attack.
Inability to call or send messages- When the attackers target your SIM, it would not work in your device. Hence, you would not be able to make calls or send texts.
Notifications of suspicious activity– In some cases, you may fall prey to the email notification from the mobile operator to activate the SIM on another device.
Denied access to accounts and apps– Finally, you may be suddenly logged out of your accounts when the attackers try to hack your SIM card.
6 Smart Ways to Prevent SIM Swapping Attacks
Even after the protection measures adopted by the carriers, criminals find their way to conduct cybercrime. Hence, you should be prepared for these situations in the following ways:
Enable SIM Lock Settings
You must use the app or site of your network provider to lock your SIM and number. This is the initial and easiest way to ensure your safety against SIM swapping attacks.
Set a SIM PIN on Your Phone
This is not like your screen password, but the SIM PIN bans access if your SIM is physically removed and used somewhere else.
Stop Using SMS for 2FA
SMS two-factor authentication is another easy step to intercept. You can use authenticator apps like Microsoft and hardware security keys to prevent cybercrimes.
Look for Carrier Alerts
If your network provider sends you an SMS or email regarding the security setting change you did not try, you should take action quickly.
Hide Your Personal Information
The fun social media quizzes often aim to extract as much information as possible. This information is used by the hackers. They can ask security questions to reset your accounts. Hence, it is a smarter way to avoid them by keeping profiles private and sharing little information online.
Implement Passkeys Stored in a Password Manager
Passkeys are modern ways to replace passwords, and they reduce the risk of SIM swapping attacks. This feature depends on public-private key cryptography and is linked to your device or biometrics. They cannot be phished or reused since they only work from your device. You should control your phone number to prevent these acts.
Concluding Remarks
SIM swapping attacks are not just random assumptions; they take place every day, everywhere, to people. However, the carriers are now implementing strong measures to mitigate this issue and stay prepared to fight back. Hence, you should consider locking your SIM through the network app, use strong 2FA, set a PIN on your device, track the notifications, and avoid sharing too much online. Protecting yourself from these risks is in your hands.
