Mint Mobile Customers on Ice: Data Breach Exposes Personal Information


Data breaches can seriously impact businesses when client information is exposed. Attackers still find methods to get around the security measures put in place for product infrastructure. An incident involving a data breach has affected Mint Mobile, a mobile virtual network operator (MVNO). The organization gave more information about the situation and confirmed the breach. Mobile virtual network operator (MVNO) Mint Mobile, known for its low prices, has revealed that it suffered a major data breach that exposed sensitive customer data and could have made SIM swapping attacks easier.

Amid the company’s T-Mobile purchase, this breach raises worries since it resembles an occurrence from 2021. The facts of the breach, its ramifications, and Mint Mobile’s response are all thoroughly examined in the firm’s report on December 22, 2023. Threat actors were able to carry out SIM switch attacks with the help of the breach, even though passwords and credit card details were apparently untouched. With the aid of top forensic cybersecurity specialists, the organization is looking into the event.

Breached client information:

  • Name
  • Telephone number
  • Email address
  • SIM serial number and IMEI number
  • A brief description of the service plan purchased

Mint Mobile assured users that no urgent action was required to safeguard their accounts despite the exposure of client information in the attack. The impacted consumers received an email stating that the root cause of the incident had been identified and resolved. This provides some comfort to Mint Mobile users who might be concerned about their personal information security. By resetting passwords and obtaining OTP codes to bypass multi-factor authentication, they can attempt to access the user’s online accounts once they get access to the number.

Threat actors may use the leaked data to launch SIM switching attacks, as the source Bleeping Computer rightly noted. Mint Mobile revealed another breach of customer data in July 2021, as mentioned above. This time, they revealed that an unauthorized attacker had transferred phone numbers and account information.
