CPNI letter from AT&T

I received a letter on letterhead purportedly from AT&T informing me that "We recently determined that an unknown and unauthorized person gained access to the number of lines on your account" and referenced Customer Proprietary Network Information (CPNI). Is this a genuine letter from AT&T?

So this is a repeat performance? How many times has CPNI been breached at AT&T? And HOW SECURE does the Passcode make the account, since AT&T has reported my information was accessed WHEN I DID INDEED HAVE A PASSCODE ON IT?!!!

Hey AT&T, i AM doing everything on my part to keep my account secure, YOU ARE FAILING.

Repeat performance of what? You replied to a 10 month old post. The letter referenced by the OP was 10 months ago.

Another attack in early March 2023. I am 1 of 9,000,000,000 customers who were sent this email on March 7th, 2023.

"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"
