Symptoms of a SIM-Swap Fraud Incident and Steps to Take Afterward
SIM swapping, or SIM jacking, is a harmful cyber attack where your cell number is redirected to another SIM and phone. Consequently, your calls, texts, and two-factor authentication codes are being sent to the wrong device, potentially leading to compromised online accounts like email and bank accounts.
To execute a SIM-swap attack, hackers attempt to convince your cellular service provider to change your existing number to a new SIM. Different providers have varying security measures in place to prevent this, but they usually require access to sensitive information, such as an address, password, or answer to a security question.
Hackers can obtain this information through standard methods like phishing emails, data breaches you have no control over, or simply by observing your conversations in a public place. They will then try to move your number to a new phone through various channels, including in-person at a store, over the phone, or online.
Not every SIM-swap attempt is successful - sometimes, you may receive a suspicious email from your phone carrier asking for confirmation on a number transfer. Even if the attack is unsuccessful, it's vital to take precautions in case there's a subsequent attempt.
Ways to protect against a SIM-swap attack
To safeguard your data and reduce the risk of your number being stolen, staying alert to potential threats is essential. Be aware of how SIM-swap attacks work and becoming knowledgeable about the risks can help.

Be careful with links sent to you via email, social media, or messenger apps. Verify their authenticity and, if possible, directly visit websites (like your bank) to log in rather than following links. Always keep your software up to date to ensure you have the latest security features. Lastly, create strong and complex passwords to further safeguard your accounts.
Discuss with your cell service provider regarding the security measures they implement to prevent SIM-swap attacks. Additionally, review the steps needed to access your online accounts to better understand the type of information potential attackers are attempting to obtain.
Enable two-factor authentication wherever possible. Using an authentication app rather than text messages for these codes can help you maintain control over your accounts even if your phone number is compromised.
Signs of a SIM-swap attack
Several clues suggest you're a victim of a SIM-swap attack: You start to miss calls and texts, have no cell signal, and receive alerts about suspicious activity in your accounts. As alarming as these issues may be, it's crucial to remain calm and act quickly to regain control of your phone number and the affected accounts.

How to respond
Prompt action is critical after a suspected SIM-swap attack. For accounts you still have access to, change the passwords and log out other devices (for example, follow the process for your Apple account).
If you're still unsure about the extent of the damage, contact your cell service provider immediately to discuss your situation. They can examine their logs for any unusual activity and may be able to restore your number. Additionally, contact your bank and other affected services to inform them of the potential attack and suspend any transactions they may consider suspicious.
Stay cautious and vigilant. You can never be too prepared when it comes to safeguarding your personal information and digital accounts.

The positive aspect is that the increasing popularity of biometrics and passcodes is making it more challenging for others to assume your identity - although not completely impossible. Should you own additional authenticated devices other than your mobile phone, such as tablets or computers, get them operational as soon as feasible to report breaches and regain control over your accounts.

Additionally, staying informed about SIM swap attacks and understanding how they work can help you identify potential threats and take prompt action if necessary.
