All three billion Yahoo users affected by 2013 mega hack

All three billion Yahoo users affected by 2013 mega hack

Shortly after Equifax revealed that its own hack compromised the data of 145.5 million people, not 143 million, Yahoo announced that a 2013 breach originally believed to have affected 1 billion people actually impacted 3 billion.

Spark - which cuts its ties with Yahoo past year - said every Xtra email that existed in 2013 was impacted by the data breach.

Yahoo on Tuesday said that every single Yahoo account was affected by a data breach that took place in 2013.

Verizon now says data from all Yahoo users was affected by a 2013 data hack.

From the investigation, the company claims that user account information who were affected did not include information such as password, credit cards, or bank accounts. It also extended complete cooperation with law enforcement in its investigation of the breach.

Email notifications requesting password changes are being sent to the additional user accounts. Yahoo was acquired by Verizon in June 2017.

Verizon would not provide any information about who the outside forensics experts are.

This big digital assault is considered the largest in the history of the internet - even when it was originally estimated to have hit one billion accounts. Yahoo notified the users it had identified at that time as potentially affected.

The tripling of the reported size of the breach - from an earlier estimate of one billion - comes after Yahoo obtained "new intelligence", the Financial Times reports. The Securities and Exchange Commission (SEC) is reportedly investigating Yahoo to determine if it alerted users to the breach fast enough. The company is still digging through the debris of the attack's aftermath, and has now come to new information from "outside the company". "Yahoo also invalidated unencrypted security questions and answers so they can not be used to access an account", Yahoo said Tuesday.

· Be cautious of any unsolicited communications that ask for your personal information or refer you to a web page asking for personal information. Chandra McMahon, chief information security officer of Verizon, said the telecoms company's investment in Yahoo was allowing the team to take "significant steps to enhance their security, as well as benefit from Verizon's experience and resources".
