AT&T Investigates Data Breach Impacting Millions, Resets Passcodes for Affected Users

Following the recent data breach, AT&T has confirmed it is currently conducting an investigation into the matter. The breach, which occurred two weeks ago, resulted in the exposure of millions of customers' data on the dark web - a restricted section of the internet only accessible through specialized software.

Impacted Users

The company has taken action by resetting the passcodes of approximately 7.6 million current users affected by the breach. Additionally, they are actively reaching out to these customers, as well as the 65.4 million former account holders whose data was also compromised.

Impact on Operations

AT&T stated in a press release that, as of today, the incident has not caused any significant impact on its operations. Nonetheless, the company continues to investigate the situation.

Data Exposed

During AT&T's preliminary review, it was discovered that the leaked data pertains to approximately 2019 or earlier. The information exposed includes personal details such as names, home addresses, phone numbers, dates of birth, and Social Security numbers. However, it is important to note that the compromised data does not contain personal financial information or call history.

Customer Guidance

AT&T has advised affected users to remain vigilant by setting up fraud alert accounts and closely monitoring their account activity and credit reports. The company is also in the process of reaching out to impacted users via email.

Past Incidents

Earlier in February, AT&T encountered a significant cellular outage lasting several hours. It was later clarified by the company that the outage resulted from a system issue, rather than a cyberattack. AT&T's CEO, John Stankey, issued an apology for the incident and provided affected customers with credits.
