Data Breach Exposes Personal Info of 73 Million AT&T Customers

• Data from about 73 million current and former AT&T customers leaked onto the dark web, including names, emails, phone numbers, Social Security numbers and account info • AT&T has reset account passcodes as a precaution and advises customers to change passwords, monitor credit, and enable two-factor authentication • Affected customers will be notified and offered free credit monitoring and identity theft protection services • This breach follows previous data breaches at AT&T's competitors T-Mobile and Verizon • The source of the data breach is still undetermined, but it may be from an AT&T vendor rather than a direct system attack
