T-Mobile CEO Mike Sievert wrote a blog post discussing the company's privacy and security in the wake of the recent data breach affecting 53 million individuals. Sievert confirmed the details of the breach, noting it involved customers, former customers and prospective customers. He also announced consumer aid, including two-year identity protection, while noting T-Mobile entered into partnerships with Mandiant and KPMG to help improve overall cybersecurity measures. Sievert's post came the same day The Wall Street Journal published an interview with the hacker who executed the breach.
