​Notice Regarding Customer Proprietary Network Information (CPNI) – Wireless Account Ending in 6811​

​Dear Hugo Cabello,​

​AT&T's commitment to customer privacy and data security is a top priority. We recently determined that an unauthorized person breached a vendor's system and gained access to your "Customer Proprietary Network Information" (CPNI). In our industry, CPNI is information related to the telecommunications services you purchase from us, such as the number of lines on your account or the wireless plan to which you are subscribed. However, please rest assured that no sensitive personal or financial information such as Social Security number or credit card information was accessed. ​

​To address this issue, the following steps have been taken:​

​·        We confirmed with the vendor that the vulnerability has been fixed.​

​ ​
• ​We have notified federal law enforcement about the unauthorized access of your CPNI as required by the Federal Communications Commission. Our report to law enforcement does not contain specific information about your account, only that the unauthorized access occurred.​
​ ​

​If you have an existing account with AT&T, you may want to consider adding our "extra security" password protection to the account at no cost. You can learn more at ​​https://www.att.com/support/article/my-account/KM1051397/​​ ​

​Please accept our apology for this incident. If you have further questions, you may visit: ​​https://att.com/data-event/login​​ You will be prompted for your myAT&T login credentials, and if you do not have a myAT&T profile, you can create one using your account information. ​

​Thank you, ​

​AT&T​
