It's been 25 years since the first PC virus (Brain A) hit the net, and what was once an annoyance has become a sophisticated tool for crime and espionage. Computer security expert Mikko Hyppönen tells us how we can stop these new viruses from threatening the internet as we know it.
As computer access expands, Mikko Hypponen asks: What's the next killer virus, and will the world be able to cope with it?
Why you should listen to him:
The chief research officer at F-Secure Corporation in Finland, Mikko Hypponen has led his team through some of the largest computer virus outbreaks in history. His team took down the world-wide network used by the Sobig.F worm. He was the first to warn the world about the Sasser outbreak, and he has done classified briefings on the operation of the Stuxnet worm -- a hugely complex worm designed to sabotage Iranian nuclear enrichment facilities. As a few hundred million more Internet users join the web from India and China and elsewhere, and as governments and corporations become more sophisticated at using viruses as weapons, Hypponen asks, what's next? Who will be at the front defending the world’s networks from malicious software? His work offers a peek into the post-Stuxnet future.
He says: "It's more than unsettling to realize there are large companies out there developing backdoors, exploits and trojans."

"Hypponen believes that malware attacks will increasingly be directed at social networks."
“Storify” is actually an obsolete word that used to be in the dictionary that means “to form or tell stories.” It’s also a word that was used internally at The Associated Press, where Burt ( co-founder ) worked as a correspondent. Editors sending messages to reporters asking them to do a story would regularly write: “Can u pls storify?”
Storify is a way to tell stories using social media such as Tweets, photos and videos. You search multiple social networks from one place, and then drag individual elements into your story. You can re-order the elements and also add text to give context to your readers.
Millions of people are sharing content through social media. But these streams of information are quickly lost in the never-ending stream of updates. With Storify, you can put together the best Tweets, photos and videos to make stories that will be remembered.
Regular blogging platform are a pain and takes a lot of time. You can cut and paste text, download and then re-upload photos, copy links to original sources, attempt to format that to look nice by going back and forth betStorifyen previews and editing modes, etc. Storify make it easy to do that by just dragging-and-dropping, creating beautiful, simple stories. Storify preserve all attribution and metadata for each element. Storify let you notify all the sources quoted in a story with one click, a great way to help it go viral. Stories with Storify are interactive, and your readers can re-Tweet or reply to the people quoted in stories. Also, Storify's API opens up new possibilities for developers to display stories in new ways and on different devices.
You can point readers to the version on your profile page at http://storify.com/your_username. But you can also take the embed code from that story and put it on any Web site, much like you would embed a Youtube video. Because it’s an embed, you will always get attribution as the source and you will be able to see where your story is embedded and how many views it gets. When readers re-Tweet elements from your story and interact with it, you’ll get the attribution as the curator.
