In a recent statement, AT&T, the largest telecommunications company in the United States, announced the discovery of a dataset for sale on the dark web containing information on approximately 73 million accounts. This includes data from around 7.6 million current AT&T customers and 65.4 million former users.
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 dataset may contain email and mailing addresses, phone numbers, and birthdates.
AT&T has contacted all affected customers via email or mail, advising them to reset their passcodes. If you're an AT&T customer, exercise caution when email prompts you to change your password. Ensure it is genuinely from AT&T, as cybercriminals might exploit this situation by sending fake emails with malicious links. If in doubt, contact AT&T support directly and request a reset link while on the phone.
The origin of the breach remains uncertain, whether it was from AT&T or a vendor. AT&T has initiated an investigation and will likely hire computer forensics specialists to determine the cause of the breach.
The company will also need to remove malware from its customer account system software without disrupting the service for unaffected customers. Addressing the breach, including the investigation, remediation, lawsuits, and legal fees, will be costly.
