T-Mobile has suffered a cyberattack exposing a small number of customers’ accounts, according to documents posted by The T-Mo Report.
According to the report, customers either fell victim to a SIM swapping attack (which could allow someone to bypass SMS-powered two-factor authentication), had personal plan information exposed, or both. The document shows that the customer proprietary network information that was viewed could’ve included customers’ billing account name, phone and account number, and info about their plan, including how many lines were attached to their account. The person who took credit for the summer hack called T-Mobile’s security “awful”
