Verizon warned an undisclosed number of prepaid customers that attackers gained access to Verizon accounts and used exposed credit card info in SIM swapping attacks.
"We determined that between October 6 and October 10, 2022, a third party actor accessed the last four digits of the credit card used to make automatic payments on your account,"
Verizon said in an alert published this week.
"Using the last four digits of that credit card, the third party was able to gain access to your Verizon account and may have processed an unauthorized SIM card change on the prepaid line that received the SMS linking to this notice. If a SIM card change occurred, Verizon has reversed it."
