Yahoo disclosed Wednesday that user data associated with “more than one billion” user accounts was stolen by a hacker in August 2013. In a statement, the company says the incident is “likely distinct” from an incident announced in September in which account data connected to 500 million accounts was stolen by what the company claimed was a “state-sponsored actor.”

The data stolen “may have” included names, email addresses, telephone numbers, dates of birth, and, in some cases, encrypted or unencrypted security questions and answers, according to Yahoo. See the full statement below, via Good Morning America:

It’s unclear how this latest announcement will affect the ongoing acquisition of the company by Verizon. In July, Verizon agreed to buy Yahoo for $4.8 billion. After the September announcement, Verizon General Counsel Craig Siliman told reporters that the breach could affect the deal, according to Reuters, and others have speculated that the breach could drive down the sale price.

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
