This was the tweet from the Associated Press on April 23: “Breaking: Two explosions in the White House and Barack Obama is injured.” Of course, it wasn’t true. The AP had been hacked. But the stock market temporarily lost more than 100 points on the news, and the tweet briefly rattled some already jittery nerves around the country.

So how does this type of hacking happen, and how can you keep it from happening to you?

Our topic this week on a special edition of the GeekWire radio show: the latest in digital security, hacking and protecting yourself online.

We’re joined in the studio by three people with different perspectives to this topic.

  • Dave Peck (@dangerdave), one of the founders of Cloak, a Seattle startup that helps computer and device users protect themselves on public wireless networks.
  • Eric Butler, a freelance software developer (@codebutler) known for creating Firesheep, a tool that demonstrated just how easy it can be to hijack someone’s online accounts on open wireless networks.

Just as we were going into the studio, the importance of these issues was illustrated yet again as news broke about  Living Social being hacked, affecting more than 50 million customers of the deals service.
