Today Yahoo! announced a big milestone in the fight against spam – we were awarded a $610 million judgment against spammers responsible for creating a fake Yahoo! lottery email scheme. This scheme was perpetrated against email users and led them to believe that they were being offered a lottery prize from Yahoo!. You can read about the actual case and the judgment issued by a New York judge here.

As a leader in anti-spam protection, we are constantly looking at how we can win the war on spam, and take several different approaches to help keep our 300-million Yahoo! Mail users as safe as possible. On the technology front, we are continually updating our technology engine to stay one step ahead of spammers. In fact, Yahoo! Mail blocks more than 600 billion spam messages each and every month (that’s over 7.2 TRILLION spam messages we block each year.) And, since introducing an updated version of Yahoo! Mail in May this year, we’ve reduced the amount of spam reported by our Mail users by an additional 60%.

More importantly, today’s ruling shows that Yahoo! goes after spammers. In a big way. We initially started building this specific case back in 2008 and have diligently been pursuing it since then. Why? Because we are vigilant about protecting you, every other Yahoo! User and the online industry in general. We do not, nor will we in the future, hesitate to bring legal action against wrong doers who are engaging in fraudulent activities across our platforms.

Is the fight against spam over? Not by a long shot. Every day the spammers try to figure out how to stay one-step ahead of the good guys, and every day Yahoo! employs the latest technology we can to stop them.

But what we can say is that today Yahoo! won a major round against spammers.

In light of this, with the roll out of the new Yahoo! Mail last May, we recently launched more advanced anti-phishing defenses and enhanced spam protection to help protect your inbox.  And we’re happy to report its success.  The Yahoo! team put together new technology that’s now blocking nearly 550 billion spam messages from hitting your inboxes each month – that’s approximately 1,800 emails for every Yahoo! Mail user.

We think the technology we’re using to keep your mailboxes safe is quite awesome and we wanted to show you how we do it, so today we’re going live with the Yahoo! Mail Visualization Project – a view of what no one has seen before using live data…how we use cloud computing and Apache Hadoop technology to filter spam and re-route email for the 300 million mail users we have across the globe.

We won’t bore you with the techy details in writing because it’s much more compelling to see…

So why is it important for us to reveal how Yahoo! Mail works? Because we’re proud to show the science and technology powering the products you use every day.  Through the visualization project, we can demonstrate the technology behind the Yahoo! Network and show the impact that the tech has on you, the consumers of Yahoo!’s great technology.  As a quick example, the anti-spam protection we mentioned earlier uses Hadoop to aggregate anonymous data from the billions of emails sent and received each day and as a result has helped us reduce spam reports by 65%.  Our technology analyzes all this anonymous data (with the help of Hadoop) and identifies spam patterns so we can then use really intelligent algorithms to predict future email patterns that will differentiate “good” and “bad” senders.

To give some perspective on how powerful our computing technology is, think about these fun facts:

• For every loving message from mom, Yahoo! Mail blocks 4 spam messages from the people she warned you about.
• In the time it takes you to read this, our Hadoop software (the brain behind Yahoo! Mail) has learned from more than 4 million user actions.
• In the time it takes sunlight to reach earth, Hadoop processes 332 million user actions, helping reduce spam in Yahoo! Mail.
• Hadoop processes 1 terabyte of data (equivalent to 4,000 years of continuous typing) in the time it takes the fastest human to run a mile.
• We add over 70 million Yahoo! Mail accounts per year – that’s the combined population of London, NYC, Paris and Tokyo.

With that we’ll leave you with the link to the Mail Visualization project.  It’s super interactive and ready for you to check it out for yourself: http://visualize.yahoo.com/

Last May, we filed a lawsuit against “Yahoo! Lottery” spammers who use our brand to trick unsuspecting users into handing over personal data to claim a prize. And we’re making progress on catching these scammers, but we’re concerned that they may step up efforts to dupe people impacted by these tough times.

Today we announced a public-private coalition with Microsoft, the African Development Bank, and Western Union to allow victims of lottery scams to upload police reports we can use with the goal of tracking down these devious criminals and developing better ways of protecting people online. INTERPOL has gotten involved to inform international law enforcement agencies about the initiative and provide guidance on critical information to collect to identify trends and common patterns.

Here’s how it works. Yahoo! and the other coalition members have set up dedicated email addresses and Web sites (ours is http://antispam.yahoo.com/phishingtips) where lottery scam victims — those who took the bait and handed over personal information — can share details of the police report they have filed. These reports may be helpful to other coalition members and law enforcement in fighting lottery scammers.

For readers who spot a scam but don’t fall for it, we have tips for you, too. First off, don’t ever reply to the message, even as a joke. You don’t want to be encouraging these guys. Instead, click the “Spam” button, which helps us and our anti-spam systems block these types of messages and kick these criminals off the Internet. We also have a form you can use to report lottery scams and other kinds of abuse originating from Yahoo! users.

As we’ve said before, no one ever wins the Yahoo! Lottery. And that’s simply because there is no Yahoo! Lottery. We’re on a mission to protect you from these online predators, but in addition to what we’re doing on our end, you can also find some tips on how you can protect yourself on our anti-spam resource site.

We recently filed a lawsuit that ought to send an unmistakable message to spammers masquerading as Yahoo! lottery commissioners, sending emails to unsuspecting users about having won a mythical jackpot. And in order to claim that jackpot, these “lucky” users simply need to hand over personal data like passwords, credit card information, and social security numbers. Some “winners” are even duped into sending money for processing and mailing charges.

We won’t tolerate these hoax emails or having our brand used to deceive you, and we’re seeking maximum damages permissible by law. This lawsuit (one of nearly ten suits to date) is part of a multi-faceted approach we’ve been taking to combat spam by supporting anti-spam legislation, creating technologies like DomainKeys, collaborating with industry leaders, and increasing consumer awareness. Consider this: every day, we block more than one billion spam and phishing messages — that’s more that four times the number of first class letters the US Postal Service delivers each day.

Besides what we’re doing on our end, here are some of the things you can do to protect yourself:

• Protect your email address like your phone number: Give it out selectively and only to people you trust. Don’t post it in public places like message boards or chat rooms. And try disposable email addresses (like our AddressGuard) for things like shopping or selling things online.
• Just say no to junk mail: Report unsolicited email by clicking on the spam button in the toolbar at the top of your inbox or message. This reports the contents so that Yahoo! Mail or your service provider can take appropriate action and potentially block them from reaching your inbox in the future.
• If it’s too good to be true, it probably is: Don’t be fooled by cash prizes or that prince who needs your help smuggling millions of dollars out of his country. They’re scams. Don’t reply, don’t click, and don’t give away any personal information.
• That’s no warning: See a pop-up ad with a warning about your computer? Or have an email from a “computer expert” warning you of a virus? They’re usually hoaxes from unscrupulous folks. Ignore them and don’t follow any steps described unless you’re sure the threat is real.
• Create a sign-in seal: Sign-in seals are a new safeguard offered by Yahoo! and many financial institutions to help protect your login. A sign-in seal is a secret message or image that you create so you can be sure you’re logging into your account and not a phishing site. To create your seal, go to any sign-in page across Yahoo! and look for the box with keys above your login.

You can find more tips on our anti-spam resource site. It’s a jungle out there, but there are plenty of ways to defend your inbox. Plus we’ve got your back.
