The exposed user account information included names, birth dates, phone numbers, security questions, and weakly encrypted passwords. Note that some people use the same password on multiple accounts and it is a dangerous practice. This could allow cybercriminals to access other accounts. Some stolen information was reportedly sold on the dark web.


Equifax security breach

A data breach at Equifax, one of the nation's largest credit reporting companies, exposed the personal information of more than 145 million Americans.


Cybercriminals exploited a website application vulnerability. The unauthorized access to data occurred between May and July 2017. Equifax announced the cybersecurity incident on September 7, 2017.


The hackers gained access to personally identifiable information that included names, Social Security numbers, dates of birth, addresses, and in some cases, driver's license numbers.

The breach likely increased the risk of identity theft for millions of Americans.


Facebook security breach

Facebook announced in September 2018 that there had been an attack on the computer network. The personal information of approximately 29 million users was exposed. Cybercriminals exploited three software flaws in Facebook's system.


Hackers managed to hack into user accounts, including those of Facebook CEO Mark Zuckerberg and Chief Operating Officer Sheryl Sandberg.
