Major Breach at AT&T: How 73 Million Customer Records Were Found on Dark Web

AT&T, the United States' largest telecommunications provider, recently revealed a significant security breach. Approximately 73 million customer records, including 7.6 million from current account holders and 65.4 million from former users, were found for sale on the dark web.

Details of the Breach: The compromised data includes passcodes (PIN numbers) and Social Security numbers dating back to 2019 or earlier. Fortunately, no personal financial information or call history details were included. However, the exposed data may contain email and mailing addresses, phone numbers, and birthdates.

AT&T has proactively contacted all affected customers via email or mail to inform them of the breach and advise them to reset their passcodes. Customers should exercise caution with any email requesting password changes to avoid phishing attempts by cybercriminals leveraging this breach. If you suspect a communication might be fraudulent, directly contact AT&T support for verification.

Investigation and Mitigation: The origin of the breach—whether from AT&T itself or one of its vendors—is currently under investigation. AT&T is employing computer forensics specialists to determine the breach's cause and is taking steps to eliminate any malware found in their systems to prevent further issues without disrupting service for unaffected customers.

Costs and Consequences: Addressing this breach will likely be costly for AT&T, encompassing investigations, system cleanups, legal fees, and potential lawsuits.
