Two US insurance companies, Washington National Insurance and Bankers Life, have warned that hackers compromised their computer systems and potentially stole personal information of thousands of individuals.
The hackers used SIM-swapping attacks to gain control of victims' phone numbers and bypass multi-factor authentication, allowing them to access sensitive information.
SIM-swapping attacks are not new, and companies and individuals should take steps to protect themselves, such as avoiding linking accounts to phone numbers and adding additional security measures to cellphone accounts.
