Data Breached Of 500 Million Starwood Guests

Recently, Marriott's guest reservation system was hacked, potentially exposing the personal information of approximately 500 million guests.

According to a news report from CNN, recently, the Marriott's cybersecurity team has found that the guest reservation system was hacked, potentially exposing the personal information of approximately 500 million guests.
 
The hotel revealed that the hack had affected its Starwood reservation database, a group of hotels it bought in 2016 that includes the St. Regis, Westin, Sheraton, and W Hotels. Hackers had unauthorized access to the Starwood reservation system since 2014, but the company found out the issue last week.

"The company recently discovered that an unauthorized party had copied and encrypted information, and took steps towards removing it," Marriott said in a statement.
 
For 327 million people, according to Marriott, hacked information includes their names, phone numbers, email addresses, passport numbers, date of birth, and arrival and departure information. While, for millions of others, their credit card numbers and card expiration dates were potentially compromised.
 
This corporate data breach in history is second behind one involving Yahoo when in 2017, over 3 billion accounts were compromised.
 
According to John Shier, Senior Security Advisor, Sophos, the potential fallout from the Marriott's Starwood data breach should be alarming to anyone who has stayed at a Starwood property in the last four years.
  
"We fell short of what our guests deserve and what we expect of ourselves. We are doing everything we can to support our guests, and using lessons learned to be better moving forward," told CEO Arne Sorenson.
 
Marriott’s security is now facing probes from multiple government bodies, including the New York Attorney General’s office. European regulators like the U.K. information commissioner, who have the ability to fine companies significant sums with the power of the General Data Protection Regulation (GDPR), are also looking into the incident.
 
Marriott's (MAR) stock is plunging on the news. The hotel chain shares witnessed a maximum 8.7 percent drop after announcing the data breach.
