Researchers Hijack Mebroot Botnet, Study Drive-By Downloads 130

TechReviewAl writes "Researchers at the University of California at Santa Barbara hijacked the Mebroot botnet for about a month and used it to study drive-by downloading. The researchers managed to intercept Mebroot communications by reverse-engineering the algorithm used to select domains to connect to. Mebroot infects legitimate websites and uses them to redirect users to malicious sites that attempt to install malware on a victim's machine. The team, who previously infiltrated the Torpig botnet, found that at least 13.3 percent of systems that were redirected by Mebroot were already infected and 70 percent were vulnerable to about 40 common attacks."

Learning Ext JS 133

stoolpigeon writes "Rich Internet Applications (RIA) have often been associated with some type of sandbox or virtual machine environment to make desktop features available via the web. Many applications though, have left behind the restrictions and demands of those technologies, implementing RIAs as pure web interfaces. One key technology in this area is JavaScript. It's been well documented that working with JavaScript can be problematic across various browsers. In response a number of JavaScript libraries have been created to alleviate the issues in dealing with different browsers, allowing developers to focus on application logic rather than platform concerns. One such library, focused on providing tools for building RIAs is Ext JS. For the aspiring developer looking to use Ext JS, Packt provides a guide to the library in the form of Learning Ext JS." Read on for the rest of JR's review.

Ex-Astronaut Developing Plasma Rocket To Revitalize NASA 277

TechReviewAl writes "Former astronaut Franklin Chang Diaz believes that the private sector can revitalize NASA, and his company is developing a plasma rocket to back up that claim. Chang Diaz argues that private industry can be used to develop much of the basic technology needed for space exploration, allowing NASA to focus on more sophisticated and critical components. His company, Ad Astra, is developing a variable specific impulse magnetoplasma rocket (VASIMR) that will be used to reposition the International Space Station. Last week, the rocket passed an important milestone in testing — reaching 200 kilowatts (enough to move the ISS). A video of the rocket can be seen on Ad Astra's site."

Is Cloud Computing the Hotel California of Tech? 250

Prolific blogger and open source enthusiast Matt Asay ponders whether cloud computing may be the Hotel California of tech. It seems that data repositories in the form of Googles and Facebooks are very easy to dump data into, but can be quite difficult to move data between. "I say this because even for companies, like Google, that articulate open-data policies, the cloud is still largely a one-way road into Web services, with closed data networks making it difficult to impossible to move data into competing services. Ever tried getting your Facebook data into, say, MySpace? Good luck with that. Social networks aren't very social with one other, as recently noted on the Atonomo.us mailing list. For the freedom-inclined among us, this is cause for concern. For the capitalists, it's just like Software 1.0 all over again, with fat profits waiting to be had. The great irony, of course, is that it's all built with open source."

Algae First To Recover After Asteroid Strike 86

pickens writes "The asteroid that impacted earth 65 million years ago killed off dinosaurs, but microalgae bounced back from the global extinction in about 100 years or less. Julio Sepúlveda, a geochemist at MIT, studied the molecular remains of microorganisms by extracting organic residues from rocks dated to the K-T extinction (in this research referred to as Cretaceous-Paleogene), and his results show that the ocean algae community greatly shrunk in size but only for about a century. 'We found that primary production in this part of the ocean recovered extremely rapidly after the impact,' says Julio Sepúlveda. Algae leave certain signatures of organic compounds and isotopes of carbon and nitrogen; bacteria leave different signatures. In the earliest layers after the asteroid impact, the researchers found much evidence for bacteria but little for algae, suggesting that right after the impact, algae production was greatly reduced. But the chemical signs of algae start to increase immediately above this layer. A full recovery of the ocean ecosystem probably took about a million years, but the quick rebound of photosynthesizing algae seems to confirm models that suggest the impact delivered a swift, abrupt blow to the Earth's environment."

Apple Takes Action Over Australian Logos 425

sams67 writes "Australian supermarket Woolworth is on the receiving end of an action from Apple over Woolworth's new logo. The green, highly stylized 'W' logo could at best be described as 'apple-like.' As outlined in the article, Apple is taking similar action in Australia against music festival promoter, Poison Apple, and pay TV provider Foxtel, over their fruit-related logos."

Submission + - People Emit Visible Light (aol.com)

Anonymous Coward writes: "The human body literally glows, emitting a visible light in extremely small quantities at levels that rise and fall with the day, scientists now reveal. Japanese researchers have shown that the body emits visible light, 1,000 times less intense than the levels to which our naked eyes are sensitive. In fact, virtually all living creatures emit very weak light, which is thought to be a byproduct of biochemical reactions involving free radicals."
