Massive Data Breach at AT&T: What You Need to Know and How to Protect Your Business

In a recent statement, AT&T, the largest telecommunications company in the United States, revealed a significant data breach. The company discovered a dataset for sale on the dark web, containing information on approximately 73 million accounts—7.6 million current AT&T customers and 65.4 million former users.

Details of the Breach

The compromised data includes passcodes (PIN numbers) and Social Security numbers from 2019 or earlier. While no personal financial information or call history was exposed, the breach may involve email and mailing addresses, phone numbers, and birthdates.

AT&T has contacted affected customers via email or mail, advising them to reset their passcodes. If you’re an AT&T customer, exercise caution with any email requesting a password change. Ensure the email is from AT&T and not a phishing attempt by cybercriminals looking to exploit this breach. If in doubt, call AT&T support directly and request a new reset link while on the phone.

Cause and Consequences

The origin of the data breach—whether from AT&T itself or a third-party vendor—remains under investigation. AT&T has initiated a thorough investigation and is likely to engage computer forensics experts to identify the breach’s cause. Additionally, they will need to remove any malware from their customer account system without disrupting services for unaffected customers. The financial implications of this breach, including investigation costs, cleanup efforts, lawsuits, and legal fees, are expected to be substantial.
