In the wake of the recent Mint Mobile data breach, it has been revealed that the company suffered a security incident that compromised the personal information of its customers. This news has understandably caused concern among Mint Mobile users, who are advised to take necessary precautions to safeguard their data and monitor their accounts for suspicious activity.
Mint is a budget-friendly mobile virtual network operator (MVNO) that provides pre-paid mobile plans.
Mint Mobile notified its customers on December 22, 2023, about the security incident via emails titled “Important information regarding your account. The email warns the customers that an unauthorized actor has obtained some limited types of customer information.
What Did the Mint Mobile Data Breach Expose?
The company confirmed that credit card numbers are not stored and they protect passwords, so the incident didn’t compromise them.
The following customer information was exposed in the Mint Mobile data breach: name, telephone number, email address, SIM serial number, IMEI number (a device identifier similar to a serial number), and a brief description of the service plan purchased.
Risks Associated with the Mint Mobile Data Breach
The exposed data is concerning, as it is enough information for a threat actor to conduct SIM-swapping attacks. In SIM swapping, the attacker ports a person’s number to their own device and gains access to the user’s online accounts by performing password resets and receiving the OTP codes to get past multi-factor authentication.
Threat actors commonly use this technique to breach accounts at cryptocurrency exchanges, stealing all assets stored in the online wallet. Mint Mobile customers should immediately secure their funds and prevent unauthorized access.
