AT&T is investigating an incident involving the illegal downloading of customer data and is working closely with law enforcement to apprehend those responsible.
In April, AT&T discovered that customer data was being illegally accessed through a third-party cloud platform. An investigation involving leading cybersecurity experts was launched to determine the extent of the breach. AT&T has since shut down the illegal access point and is working with law enforcement, resulting in at least one arrest.
The compromised data includes call and text message records for nearly all AT&T wireless customers, mobile virtual network operators (MVNOs) using the AT&T network, and AT&T landline customers who interacted with those wireless numbers between May 1, 2022, and October 31, 2022. For a small number of customers, records dated January 2, 2023 were also compromised. The data identifies phone numbers interacted with during those time periods, and for some records, one or more cell site identification numbers are included.
The compromised data does not include call or SMS content, social security numbers, birth dates, or other personally identifiable information. Typical usage details such as timestamps of calls or SMS are also missing. Although customer names are not included, it is often possible to determine a name using publicly available tools.
At this time, AT&T does not believe the data is publicly available. The company's top priority remains its customers. Affected customers are being notified and informed of appropriate resources. AT&T deeply regrets the incident and remains committed to protecting customer data. For more details, visit att.com/DataIncident.
Benefits of a digital security protocol for small businesses
Implementing a strong digital security protocol is important for small businesses to protect their sensitive data. First, it helps protect customer information and ensure that personal and financial data is not exposed to cybercriminals. This not only protects customers but also builds trust and loyalty, which is crucial for maintaining a positive reputation.
Second, a strong digital security protocol can prevent financial losses. Cyberattacks can result in financial damage through fraud, theft, or system failure. By securing digital assets, small businesses can avoid these costly incidents and ensure business continuity.
Third, compliance with legal and regulatory requirements is another benefit. Many industries have regulations that require the protection of customer data. A comprehensive security protocol helps companies comply with these regulations and avoid fines and legal consequences.
In addition, digital security protocols help protect intellectual property and proprietary information. For small businesses, innovative ideas and unique products are often their most valuable assets. Protecting these assets from cyber threats is key to maintaining competitive advantage.
In addition, a security protocol increases overall operational efficiency. Regular updates and maintenance of security systems ensure that business operations run smoothly and without interruptions due to cyber incidents. This also includes training employees on best practices, which reduces the risk of human errors leading to security breaches.
Finally, investing in digital security can improve a small business's market position. Customers and partners prefer to do business with companies that are committed to protecting their data. This can lead to more business opportunities and growth.
