The Internet service company Yahoo! reported two major data breaches of user account data to hackers during the second half of 2016.
 The first announced breach, reported in September 2016, had occurred sometime in late 2014, and affected over 500 million Yahoo! user accounts.
 A separate data breach, occurring earlier around August 2013, was reported in December 2016, and affected over 1 billion user accounts.
 Both breaches are considered the largest discovered in the history of the Internet.
 Specific details of material taken include names, email addresses, telephone numbers, encrypted or unencrypted security questions and answers, dates of birth, and hashed passwords. Further, Yahoo! reported that the late 2014 breach likely used manufactured web cookies to falsify login credentials, allowing hackers to gain access to any account without a password.
The 2014 JPMorgan Chase data breach was a cyber-attack against American bank JPMorgan Chase that is believed to have compromised data associated with over 83 million accounts – 76 million households (approximately two out of three households in the country) and 7 million small businesses.
 The data breach is considered one of the most serious intrusions into an American corporation's information system and one of the largest data breaches in history.
In June 2015, the United States Office of Personnel Management (OPM) announced that it had been the target of a data breach targeting the records of as many as four million people.
 Later, FBI Director James Comey put the number at 18 million.
 The data breach, which had started in March 2014 or earlier, was noticed by the OPM in April 2015.
 It has been described by federal officials as among the largest breaches of government data in the history of the United States.
 Information targeted in the breach included personally identifiable information such as Social Security numbers, as well as names, dates and places of birth, and addresses.
 The hack went deeper than initially believed and likely involved theft of detailed security-clearance-related background information.
In March 2016, the personal Gmail account of John Podesta, a former White House chief of staff and the chairman of Hillary Clinton's 2016 U.S. presidential campaign, was compromised in a data breach, and a collection of his emails, many of which were work-related, were stolen.
 Cybersecurity researchers as well as the United States government attributed responsibility for the breach, which was accomplished via a spear-phishing attack, to the hacking group Fancy Bear, allegedly affiliated with Russian intelligence services.
Security breach notification laws or data breach notification laws are laws that require an entity that has been subject to a data breach to notify their customers and other parties about the breach and take other steps to remediate injuries caused by the breach.
 Such laws have been enacted in most U.S. states since 2002.
 These laws were enacted in response to an escalating number of breaches of consumer databases containing personally identifiable information.
