Yahoo yesterday announced that Yahoo mail has been the focus of a co-ordinated hack and that at this time it has confirmed a number of users e-mail accounts have been compromised – you may be one of them (and if you are see below for my top tips on how to secure your passwords going forward). It is not clear how many users have been compromised, or exactly how. Yahoo don’t have a history of providing much information but it would be prudent for any Yahoo mail users to take precautions.

Usernames and passwords of some of Yahoo's email customers have been stolen and used to gather personal information about people those Yahoo mail users have recently corresponded with, the company said Thursday.

Yahoo! Inc. Chief Executive Officer Marissa Mayer has failed to spur growth at the Web portal 18 months after taking the job -- and the outlook isn’t improving as advertisers continue spending their money elsewhere.

Following lackluster earnings, Yahoo CEO Marissa Mayer stressed a turnaround would take years. Investors may not give her that much time.

What’s that old saying? Software will eat the world? That was never more evident than at CES 2014. Now that the dust has settled, the Gorkana Group has released a social insight report for the event, and one thing is instantly clear: Yahoo CEO Marissa Mayer won the show.

Let’s go back in time. In 2005, Yahoo purchased 40 percent of the Chinese ecommerce company Alibaba for $1 billion. The move would later all but save the American company. While Yahoo, under the leadership of its yet-new CEO Marissa Mayer has shown fresh dynamism, and has rebuilt its reputation in the technology market as its mobile push has matured, the company’s core financial performance metrics have dragged.

Yahoo chief executive officer Marissa Mayer has been under a microscope ever since she took over the company in 2012. But now, with the pricey firing of chief operating officer Henrique de Castro, the former Googler is under even more scrutiny. De Castro will walk away from Yahoo with up to $109 million, according to reports citing research from Equilar, an executive compensation and corporate-governance data firm.

When Yahoo redesigned its webmail service two months ago, it got rid of tabs, a feature the company says often confused users when they had too many open. That feature was later replaced by a "recent" view, which showed the last few messages in a short list. Now Yahoo has brought tabs back with another feature designed to let users with tons of tabs quickly see what they're working on.

Yahoo may be working on its own voice-based personal assistant to rival Apple's Siri and Google Now. A video has recently surfaced that shows the unreleased app running on an Android smartphone. The origins of the clip are unclear, though it may have been developed for internal purposes. In the video, we see the Android device mounted in a car. The driver turns on the engine, and without any voice prompts (or forward movement), the app recognizes that he's headed to the office.

Found this as I was cleaning up some backups from almost 15 years ago.  THought it would be interesting to let people see what my goals were for our merger with Yahoo back then.

Yahoo CEO Marissa Mayer wrote a blog on Tumblr saying how “very sorry” she is for the inconvenience and frustration the Yahoo outage caused to its users. She also explained the cause of the very long “scheduled maintenance.”

Normally a report of a web services outage goes like this: web service goes down, reporter writes post, hits publish, web service comes right back up. But that doesn’t appear to be the case for Yahoo Mail, which has been down for some users for well over 24 hours, and in some cases nearly two days, if the reports on Twitter and those rolling into our tips inbox are to be believed.

This fall, Yahoo began serious talks to buy photo-sharing site Imgur, a source with first-hand knowledge of those discussions tells us. Since she joined Yahoo in July 2012, CEO Marissa Mayer has acquired dozens of startups. Most of these acquisitions have been acqui-hires.

As one of Google’s highest-ranking women, Marissa Mayer became a Silicon Valley superstar, but inside the search giant her dazzle sometimes wore thin, with colleagues rebelling against her imperious style. In the wake of Mayer’s jump to run the struggling Yahoo, Bethany McLean asks whether she will be its savior or its next big problem. A year and a half in, the results are mixed.

Miley Cyrus was officially the most searched term overall on Yahoo in 2013, beating out more serious issues like the hotly debated Affordable Care Act, aka Obamacare. In related news, the most popular question starting with "What" happened to be "What is twerking?"

Yahoo has acquired SkyPhrase, a natural language processing startup, in a move that could improve Yahoo’s ability to make sense of user queries and commands across any number of Yahoo products. Terms of the deal, which was announced Monday, were not disclosed. SkyPhrase’s team has joined Yahoo’s Labs business unit in New York City, a Yahoo spokeswoman said.

Marissa Mayer became the CEO of Yahoo on July 16, 2012. Since then, the stock has exploded from ~$16 to over $35.

Beginning Jan. 8, Yahoo will enable encryption by default for users logging into its Web-based mail service, the company has told The Washington Post.

Three weeks ago, Yahoo Inc Chief Executive Marissa Mayer strode into a Manhattan hotel and was greeted like a rock star by hundreds of advertising executives who snapped pictures as she sat down for an interview with journalist Charlie Rose.

Yahoo, it seems, just can’t do anything right when it comes to winning friends in the security industry. First, they came up with a bonkers scheme for recycling old email addresses – not apparently realizing that the danger of identity theft to which it was exposing the original account holders.
