Biggest data breaches have been suffered
▸The case of Marriot
After Marriott reported that hackers had stolen personal information from half a million customers since 2014, lawsuits have been filed against the hotel company in the amount of $ 12.5 billion. the information stolen from your guests includes date of birth, telephone numbers, passport number, credit cards and their expiration date.
Marriott has more than 6,700 properties worldwide and 30 hotel brands. And this still does not know from where or who carried out this attack.
▸Yahoo!
The company, which was sold to Verizon in July 2016, admitted in 2017 that the hack was bigger than it thought, since it reached the entire digital platform and not just part of it. In an official statement, Oath, the Verizon division in charge of Yahoo, said at the time that all of its customer accounts had been affected. The hackers obtained security questions and email addresses used to reset passwords.
Unfortunately shortly after suffering this attack. In December 2014, a large-scale data breach left at least 500 million accounts exposed (it became public in 2016). On that occasion, names, email addresses, phone numbers, passwords and, in some cases, security questions were compromised. The US Department of Justice blamed four Russian individuals.

773 million email addresses, 2,692,818,238 lines with user and password combinations that make a total of 1,160,253,228 combinations. In total, 22 million unique passwords leaked in a file that comes from various sources and considered the largest leak in history, also taking into account that users often repeat passwords.
The list of passwords has been uploaded to the famous platform of have I been pwned? In which you can check if your password has been exposed.
