No need to crack RSA when you can guess the key File-encrypting ransomware Trojans are almost ubiquitous on Windows, and it was only a matter of time until the advent of the first piece targeting Linux. Dubbed Linux.Encoder.1, this first piece of Linux ransomware is extremely similar in behavior to CryptoWall, TorLocker and other notorious ransomware families for Windows.

In Norway, doctors are clinging to older MS DOS-based electronic journals. As a result there's a system in place that still employs floppy disks-and it works extremely well. But a blog post on Gundersen.net says the Norwegian government might be retiring the floppy disk option as soon as next year.

Set aside the ad-blocking debate for a moment. The biggest development in advertising right now may not about whether you watch the ads, but whether the ads are watching you.

Last year, NASA's advanced propulsion research wing made headlines by announcing the successful test of a physics-defying electromagnetic drive, or EM drive. Now, this futuristic engine, which could in theory propel objects to near-relativistic speeds, has been shown to work inside a space-like vacuum.

This 2013 graphic shows the cloud of space junk surrounding Earth.Credit: NASA's Goddard Space Flight Center/JSC The International Space Station could one day get armed with a laser to shoot down orbiting debris, researchers say. This concept could eventually lead to a laser-firing satellite that could get rid of a large percentage of the most troublesome space junk orbiting Earth, scientists added.
