US warns airlines about onboard Wi-Fi hacking

Here's one more thing for nervous flyers to worry about: Two U.S. federal agencies are advising airlines to look out for signs that passengers may be trying to hack into planes' navigation systems via Wi-Fi or onboard entertainment systems, Wired reports.

Drone lands on Japanese Prime Minister's roof

The out-of-control drone that crashed on the White House lawn in January seemed to be a harmless accident; less so the camera-equipped drone carrying a bottle marked with the radioactive symbol that was discovered on the roof of the Japanese prime minister's office in central Tokyo on Wednesday morning.

Republican Senator fast-tracks extension of NSA bulk surveillance

Contrary to expectations that U.S. lawmakers would move to stop the NSA from collecting phone records in bulk, the leader of the Republican majority in the Senate on Tuesday introduced legislation to extend the NSA's broad surveillance power before it expires in June, the Hill reports.
