  Brave new risks of nanotechnology 

  http://www.ft.com/cms/s/1/a0bbffa6-65fa-11dc-9fbb-0000779fd2ac.html

  Never underestimate the ability of an American consumer to overestimate risk: when it comes to food, toys and drugs, we Americans think we have a fundamental constitutional right to total safety. A dab ... of lead paint here, a spot of e-coli there, the slightest whiff of risk (however infinitesimally small) spells doom in the market. Consumer hysteria feeds on itself, and soon the whole nation is throwing out its toys. But the panic over Chinese imports, which could spawn years of lawsuits and reams of government regulations, may pale by comparison with an even bigger consumer crisis on the horizon: the battle over the risks and rewards of nanotechnology. The science of these Franken-molecules is still in its infancy, but already nanoparticles are being used or developed for use in consumer products from sunscreen to stain-proof ties, stink-free refrigerators, and contact lenses that change colour according to blood-sugar levels (allowing diabetics to test their blood by simply looking   [More...] [Less...]

  Exploiting Web 2.0: Barbarians inside the firewall 

  http://www.networkworld.com/news/2007/092107-exploiting-web-20-barbarians-inside.html

  It is also becoming more and more difficult to distinguish malicious from nonmalicious sites. Google recently published a paper from researching sites it crawls (see " The Ghost in the Browser "), and ... found that one in 10 websites contains a malicious payload. Most users would be hard-pressed to distinguish the malicious 10 percent from a random set of search results. Once inside the firewall, these covert applications can steal confidential data, infect other machines and launch spam or malicious attacks. The "new new" threat: Botnets The most sophisticated of these new threats are botnets. These collections of software robots known as "bots" run on compromised computers called "zombies" that can be controlled by "bot herders" through a communications infrastructure named "command and control" or "C&C" for short. The value of a botnet is directly proportional to the number of machines it controls, the value of those machines (for example, .com versus .org, if data theft is the goa   [More...] [Less...]
