The website "Have I Been Pwned", or HIBP, was created by Microsoft Regional Director Troy Hunt as a free resource for the public to check if their personal data had been compromised by a breach on the internet. You can visit HaveIBeenPwned.com and enter your email address or account password to see if either had been involved in a data breach. The way Troy has built the site ensures visitors can enter their passwords safely and securely.
Marriott just announced this week that it learned of a security breach from four years ago, and 500 million users are affected. For 327 million guests, the exposed information include names, phone numbers, email addresses, passport numbers, and arrival and departure information. For millions of others, credit card numbers and expiration dates were compromised. Marriott says it will begin emailing guests affected by the breach.
