AT&T, a Dallas-based telecommunications company, recently disclosed its second data breach of the year, impacting over 100 million U.S. customers. The breach, which occurred due to a malicious actor illegally accessing AT&T’s workspace, compromised communication records from specific dates in 2022 and 2023. This breach follows a previous one that exposed social security numbers and names of 73 million AT&T customers to the dark web.
When facing a data breach, it is essential to take proactive measures to safeguard your personal information. Mitch Thornton, Executive Director of the Darwin Deason Institute for Cybersecurity at Southern Methodist University, emphasizes the importance of protecting one’s systems and access to third-party accounts. AT&T has committed to notifying affected users and providing identity theft and credit monitoring services. However, there are proactive steps individuals can take to mitigate potential risks.
Monitor Your Credit and Transactions
One of the initial steps following a data breach is to monitor your credit for any suspicious activity. Criminals often test the waters by making small purchases to see if they go unnoticed. Thornton advises individuals to review credit card transactions meticulously and not overlook any unexpected charges. Resetting passwords and enabling two-factor authentication are crucial security measures to prevent unauthorized access to accounts.
Implement Credit Freezes and Locks
Consider implementing credit freezes or locks to restrict unauthorized access to your credit reports. While both measures serve a similar purpose, credit locks typically involve a cost and instant application, whereas credit freezes are free but may require a few business days to take effect. These safeguards can prevent fraudulent attempts to open new accounts using compromised information.
Utilize Security Software
While protecting data stored by third-party entities like AT&T may be challenging, investing in security software for personal systems can enhance overall protection. Thornton suggests using reputable security software to fortify home systems against potential cyber threats. Despite the limitations in guarding against third-party breaches, security software remains a valuable tool in combating malicious activities.
In the aftermath of a data breach, individuals should remain vigilant against phishing scams and fraudulent communications. Cybercriminals may attempt to exploit the situation by impersonating legitimate entities like AT&T to obtain sensitive information. Thornton advises individuals to verify the authenticity of any requests for personal information and contact companies directly to confirm the legitimacy of such requests.
The AT&T data breach serves as a stark reminder of the prevalent risks associated with cyber threats and identity theft. By taking proactive steps to safeguard personal information and adopting security best practices, individuals can mitigate the impact of data breaches and protect themselves from potential vulnerabilities. Remaining informed, vigilant, and proactive are key principles in navigating the evolving landscape of cybersecurity threats.
