Verizon says Yahoo email hacking could scupper $4.83 billion deal The company said in a statement Wednesday after the markets closed that unnamed attackers stole the accounts in August 2013, a year prior to a previously disclosed attack, in which attackers stole around 500 million accounts in September 2014. The company wasn't able to identify the intrusion associated with the August 2013 breach.
Yahoo's massive data breach could affect hundreds of millions of users. One-time Internet pioneer Yahoo was recently the focus of a bidding war for its core assets, which were scooped up by AOL owner Verizon. SAN FRANCISCO -- Information from at least 500 million Yahoo accounts was stolen from the company in 2014, and the company said Thursday it believes that a state-sponsored actor was behind the hack. The information may have included names, email addresses, telephone numbers, dates of birth, and, in some cases, encrypted or unencrypted security questions and answers, Yahoo said. Claims surfaced in early August that a hacker using the name "Peace" was trying to sell the usernames, passwords and dates of birth of Yahoo account users on the dark web -- a black market of thousands of secret websites.
NEW YORK – The revelation of Yahoo's latest hack underscores what many Americans have known for years: All those emails, photos and other personal files stored online can easily be stolen, and there's little anyone can do about it. The only saving grace is that the attackers apparently did not exploit the information for fraud. But their true motives remain a mystery. While there are a number of straightforward measures all users should take to protect themselves, relatively few people actually do. And in this case, doing so wouldn't really have mattered.
Since 2010, billions of sensitive files, personal information and account details have been leaked thanks to devastating hacks and damaging breaches. As more sensitive personal data has made its way online, the size and impact of breaches has steadily increased throughout the decade. Attacks have hit almost every sector and show no signs of slowing down as more people are forced to entrust the safety of personal information to various websites. "For me, the largest hacks of the decade are not just the ones that were the biggest, but the ones that were game-changers in how we approach security. If we had this talk 10 years ago, we would be blown away by the numbers, but now, the numbers don't really affect us that much," said Etay Maor, chief security officer at the cybersecurity firm IntSights.
