Over 10 million people who have stayed at MGM Resorts hotels – including Twitter boss Jack Dorsey and pop idol Justin Bieber – have had their personal details posted online by hackers.
The security breach, publicised by ZDNet and security researcher Under the Breach, saw the records of 10,683,188 former guests – including names, postal addresses, phone numbers, dates of birth, and email addresses – made available in an online data dump.
According to breach notification service HaveIBeenPwned, over three million unique email addresses were included in the stash, opening opportunities for online fraudsters and other cybercriminals to exploit the information.
High profile names in the leaked database include Jack Dorsey and Justin Bieber, alongside journalists, company executives, FBI agents, and government officials.
