Over the past few days, Twitter has been helping folks victimized by a phishing attack. Phishing is a deceitful process by which an attempt is made to acquire sensitive information such as Twitter usernames and passwords. The bad guys masquerade as someone you trust and may send you a Direct Message (DM) with a link. This DM may say something along the lines of, "LOL that you??" followed by a link to a fake Twitter login page. If you enter your credentials on that fraudulent page, the phishers can sign in as you and trick more people.

Anatomy of A Phishing Scam

Generally a phishing attack against Twitter users breaks down to a three-part process. First, accounts compromised in the manner described above send out messages to all accounts following them. Second, accounts that are newly compromised send out more messages. Third, the scammers behind the phishing attack make an attempt at monetization by sending out spam links instead of links to a fake login page. We fight phishing scams by detecting affected accounts and resetting passwords. However, it's better to stop them before they start.

Avoiding Phishing Scams

We designed the Direct Message system so that you could only get DMs from accounts that you choose to follow—this cuts way down on spam and attacks. Our Trust and Safety team identifies and deletes spam accounts every day. Still, we recommend against indiscriminately following hundreds or thousands of accounts without having a look first. To learn how you can avoid falling victim to a phishing scam or if you have other questions about keeping your Twitter account secure, please read status blog that we update regularly.

In other words: Yahoo! People want to discover and share tweets everywhere ranging from SMS and TV, to apps and the Web. For a global network of 600 million people, Yahoo! represents the Web. Similar to the partnerships we have made with other large internet companies, Yahoo! will receive what has been dubbed "Firehose"—a full feed of public tweets sent to Twitter and our partners every second of every day from all around the world.

Through this arrangement, people will be able to find relevant tweets in Yahoo! Search as well as other popular products and properties, including the Yahoo! Homepage, Yahoo! Mail, Yahoo! Sports, and more. Yahoo! will also be able to build unique Twitter clients into their properties making it easier for folks to tweet wherever they feel comfortable within the Yahoo! network.

From our perspective, this partnership represents a big opportunity. Tweets may be short, but they have proven over and over again to contain valuable information. As the Twitter information network grows and expands, it becomes more valuable for everyone who participates. Our open approach helps us get closer to providing universal connectivity to a global network of immediate information.

Hi, I'm the other performance, @twittereng on Twitter itself.

As a member of the Twitter analytics team, part of my job is to measure and understand growth. The graph above tells a story of how we've grown over the past three years in terms of number of tweets created per day. Please note that tweets from accounts identified as spam have been removed so the counts in this chart do not include spam.

Folks were tweeting 5,000 times a day in 2007. By 2008, that number was 300,000, and by 2009 it had grown to 2.5 million per day. Tweets grew 1,400% last year to 35 million per day. Today, we are seeing 50 million tweets per day—that's an average of 600 tweets per second. (Yes, we have TPS reports.)

Tweet deliveries are a much higher number because once created, tweets must be delivered to multiple followers. Then there's search and so many other ways to measure and understand growth across this information network. Tweets per day is just one number to think about. We'll make time to share more information so please stay tuned.

If you have been following the events in Haiti since the devastating quake last month, then you know of the initial bursts of compassion. International dialogue now shifts from lifesaving relief to long term restoration. Officials are saying this may take ten years at a cost of billions.

Post-disaster needs assessment is underway and there will be an international donor conference late next month in New York City. In the meantime, there are ways to stay involved in sustained efforts such as the WFP's monthly donation program.

My name is @TheSaints recovered a surprise onside kick, and for the next minute 44% of all worldwide tweets were about football. Chatter around brands had meanwhile dropped to much lower levels until Parisian Love commercial sparked viewers once more. Excitement around the game grew steadily with large peaks following scores and turnovers up until the final moments. As the game ended, one out of every two tweets on Twitter was about the Super Bowl!

Every day millions of people interact with Twitter to share and discover what's happening now. Major events like the Super Bowl focus people around a few common topics. There is real value in being able to measure the reach and influence of those topics in real time, and we in the analytics team are looking forward to a lot more where this came from. On to the Winter Olympics...

twitter.com to read and write tweets, we've been spending some time focusing on ways to improve your experience on the site. Today, we're introducing a feature called Hovercards that will be a handy way to interact with the folks behind each tweet.
