According to a post by ZDNet, 10.6 million MGM Resorts hotels guests have had their personal details published to a hacking website this week. ZDNet verified the authenticity of the data today, together with a security researcher from Under the Breach, a soon-to-be-launched data breach monitoring service. The leaked files that were released contain the personal and contact details not just for regular tourists, but also for celebrities, tech CEOs, reporters, government officials, and employees at some of the world’s largest tech companies. Twitter CEO Jack Dorsey, pop star Justin Bieber, and DHS and TSA officials are some of the big names Under the Breach spotted in the leaked files. Included in the leaked files are personal details such as full names, home addresses, phone numbers, emails, and dates of birth. MGM confirmed that they had a breach last summer and notified affected guests. MGM told ZDNet, “We are confident that no financial, payment card or password data was involved in this matter.” While the breach suffered by MGM is no where near as big as the Marriott breach of 2017, the leaked data is a treasure trove of contact details for many high-profile users, working for big tech firms and governments all over the world. These users now face a higher risk of receiving spear-phishing emails, and being SIM swapped. Need help preventing or dealing with a breach?
