Whole internet probed for insecure devices. 21 March 2013Last updated at 07:34 ET The project probed millions of devices connected to the net A surreptitious scan of the entire internet has revealed millions of printers, webcams and set-top boxes protected only by default passwords.
An anonymous researcher used more than 420,000 of these insecure devices to test the security and responsiveness of other gadgets, in a nine-month survey. Using custom-written code, they sent out more than four trillion messages. The net's current addressing scheme accommodates about 4.2 billion devices. The number of addresses responding was a surprise as the pool of addresses for that scheme has run dry. The scan found half a million printers, more than one million webcams and lots of other devices, including set-top boxes and modems, that still used the password installed in the factory, letting almost anyone take over that piece of hardware.

It all started when I shot the sunset panorama below from one of the locations where I work.
It shows a horizontal field of view comparable to a 60mm lens on a 35mm film camera. There is nothing exceptional about this panorama except maybe that it shows -- on the righthand side -- the Zugspitze which happens to be Germany's highest mountain. The Zugspitze is 2962 m (or 9718 Ft) high and from the point where the photo was taken, exactly 83.39 km (or 52 miles) away. So, I thought it may be a good idea to crop into that image and look what guys are doing up there on mountain top ;) Theoretically, such a crop should be feasible because the image actually was stitched from several images taken with the FA* 300mm f/4.5 lens on the Pentax K-7 each. Below is what the crop (100% pixel level and corresponding to a 2000mm lens on 35mm film) looks like: Really looks blurry as if it were out of focus or having motion blur. 1.
