Taking Apart the Energizer Trojan 55

iago-vL writes "Researchers at SkullSecurity have written a tutorial on how they reverse engineered the Energizer Trojan and generated an Nmap probe to remotely detect infections. The Energizer Trojan is a great educational tool because its inner workings are very simplistic, and it makes minimal efforts to hide itself or conceal its purpose; it even lists what appears to be the author's name — 'liuhong' — in the source! The article provides an introduction to malware analysis, from infecting a test machine to debugging and disassembling the Trojan to writing the actual probe."

Trio of Super-Earths Discovered 178

FiReaNGeL writes "A group of astronomers have now discovered a system of three super-Earths around a rather normal star, which is slightly less massive than our Sun, and is located 42 light-years away towards the southern Doradus and Pictor constellations. 'We have made very precise measurements of the velocity of the star HD 40307 over the last five years, which clearly reveal the presence of three planets.' The planets, having 4.2, 6.7, and 9.4 times the mass of the Earth, orbit the star with periods of 4.3, 9.6, and 20.4 days, respectively. 'The perturbations induced by the planets are really tiny — the mass of the smallest planets is one hundred thousand times smaller than that of the star — and only the high sensitivity of HARPS made it possible to detect them' says co-author François Bouchy, from the Institut d'Astrophysique de Paris, France. Clearly these planets are only the tip of the iceberg."

Real-time Raytracing For PC Games Almost A Reality 292

Vigile writes "Real-time raytracing has often been called the pinnacle of computer rendering for games but only recently has it been getting traction in the field. A German student, and now Intel employee, has been working on raytraced versions of the Quake 3 and Quake 4 game engines for years and is now using the power of Intel's development teams to push the technology further. With antialiasing implemented and anisotropic filtering close behind, they speculate that within two years the hardware will exist on the desktop to make 'game quality' raytracing graphics a reality."
