Tech secrets: 21 things 'they' don't want you to know

The NSA Is Tapping Your Data Stream

Remember all the hubbub about the Bush administration's warrantless wiretapping? Nowadays, the National Security Agency still sifts through the petabytes of information traveling along the nation's fiber backbone--but legally, thanks to some after-the-fact lawmaking by Congress.

Some quick background: In December 2005, the New York Times reported that the NSA had engaged in domestic digital surveillance without U.S. court approval. In January 2006, former AT&T technician Mark Klein provided documents to the Electronic Frontier Foundation confirming that the NSA had installed surveillance equipment at a major Internet hub in San Francisco.

In 2006 and 2008, the EFF filed suit against AT&T and the federal government, respectively, over warrantless wiretapping. Both suits were rebuffed by federal courts and are currently on appeal. In July 2008, Congress passed a bill granting retroactive immunity to telecoms for their participation in the NSA's wiretaps.

"What people don't know and should is that there is a dragnet sucking up all their communications so the government can review them," says the EFF's Jennifer Granick. "AT&T is still routing all of its data traffic through the NSA."

The Fix: Short of pulling a Ted Kaczynski and holing up in a cabin in Montana, there isn't much you can do. Last September, four Democratic senators introduced the Retroactive Immunity Appeal Act, which would make telecoms accountable for their role in warrantless spying, but the bill hasn't gotten far. In the meantime, avoid googling "Osama" and "improvised explosive device" on the same day, unless you enjoy surprise visits from the Men in Black.

Your Facebook Apps Are Spying on You

Sure, it's silly and fun to play Mafia Wars or to take one of the 2,345,678 quizzes on Facebook. When you install one of these apps, though, it gains access to any information you've designated as available to 'Everyone'. Per Facebook's Platform guidelines, this can include a huge amount of information, including your name, photo, birthday, location, job history, religion, political point of view, relationships, favorite books and movies, and so on. Much of this information is shared by default. It's the motherload for data miners.

Facebook requires each app to adhere to your privacy preferences and to have its own privacy policy, but it doesn't require apps to have a very good policy. Some, like Farmville's policy, are fairly comprehensive; others appear to have been written by 12-year-olds.

The Fix: Facebook recently introduced privacy controls that help limit what information apps can access. Use them. To start, log in and go to Account, Privacy Settings, Profile Information. Change any setting marked 'Everyone' to Only Friends or Friends of Friends. Then go to Applications and Websites, What your friends can share about you, and uncheck most if not all of the boxes.
