Frankenstein Code Stitches Code Bodies Together To Hide Malware 111

mikejuk writes "A recent research technique manages to hide malware by stitching together bits of program that are already installed in the system to create the functionality required. Although the Frankenstein system is only a proof of concept, and the code created just did some simple tasks, sorting and XORing, without having the ability to replicate, computer scientists from University of Texas, Dallas, have proved that the method is viable. What it does is to scan the machine's disk for fragments of code, gadgets, that do simple standard tasks. Each task can have multiple gadgets that can be used to implement it and each gadget does a lot of irrelevant things as well as the main task. The code that you get when you stitch a collection of gadgets together is never the same and this makes it difficult to detect the malware using a signature. Compared to the existing techniques of hiding malware the Frankenstein approach has lots of advantages — the question is, is it already in use?" Except for the malware part, this has a certain familiar ring.

LiftPort Wants To Build Space Elevator On the Moon By 2020 210

Zothecula writes "When the late Neil Armstrong and the crew of Apollo 11 went to the Moon, they did so sitting atop a rocket the size of a skyscraper that blasted out jets of smoke and flame as it hurtled skyward. For over half a century, that is how all astronauts have gone into space. It's all very dramatic, but it's also expensive. Wouldn't it be cheaper and easier to take the elevator? That's the question that Michael Laine, CEO of LiftPort in Seattle, Washington, hopes to answer with the development of a transportation system that swaps space-rockets for space-ribbons. LiftPort ultimately wants to build a space elevator on Earth, but the company isn't planning on doing it in one go. Instead, Laine and his team are settling for a more modest goal – building an elevator on the Moon by 2020. This is much easier. For one thing, there’s no air on the Moon, so no icing problems. Also, the lower gravity means that no unobtainium is needed for the ribbon. Kevlar is strong enough for the job. And finally, there’s very little in the way of satellites or debris to contend with."
