We looked into this and can confirm it is a legitimate email. There is not a system-wide issue affecting a number of Yahoo Mail users.
If we detect unusual activity on an account, we will prompt the user to change their password. This is part of our ongoing security efforts to keep our users' accounts and their data secure.In the not-so-aside meantime ... The more I use Yahoo! these days, the more I want to return to being bullish. As I discussed last week on CNN's "The Lead with Jake Tapper", Google ( GOOG) has this curious edge in that its content seems to stick more. By that I mean it appears users engage more and spend more time with Google content. That's largely because of YouTube, but it also has a lot to do with how Google ties search results in with its other still-emerging platforms. Clearly, Marissa Mayer is trying to get Yahoo! to that place. That's certainly part of the method behind the Tumblr acquisition as well as the recent pickup of the great consumer tech personality David Pogue, formerly of The New York Times. That's a move we should not overlook. While it's a different and riskier strategy than Google's, Mayer appears to be assembling talent across Yahoo!'s dynamic platforms. This core of what we can coldly refer to as "intellectual property" can produce Google-like loyalty from Yahoo! users as it comes together. It just doesn't happen overnight. But that's the hallmark of most long-term and sustainable fixes, not short-term and quick band-aid approaches. In other words, as Mayer's strategy continues to take shape I'm getting closer to the bullishness I expressed ahead of YHOO's massive run which kicked off last summer.
