“3-Day Training: The ARM Exploit Laboratory”

Posted by fidest press agency su mercoledì, 27 febbraio 2019

The all new ARM IoT Exploit Laboratory is a fast paced 3-day intermediate level class intended for students who want to take their exploit writing skills to the ARM platform. The class covers everything from an introduction to ARM assembly all the way to Return Oriented Programming (ROP) on ARM architectures. Our lab environment features hardware and virtual platforms for exploring exploit writing on ARM based Linux systems and IoT devices.The class concludes with an end-to-end Firmware-To-Shell hack, where we extract the firmware from a popular SoHo router, build a virtual environment to emulate and debug it, and then use the exploit to gain a shell on the actual hardware device.

Applied DNA Expands Internationally with New Central DNA Testing Laboratory in India

Posted by fidest press agency su mercoledì, 24 gennaio 2018

DNAApplied DNA Sciences, Inc. (NASDAQ:APDN, “Applied DNA,” “the Company”) today announced the establishment of a Central DNA Testing Laboratory in Ahmedabad, India providing full forensic authentication services. The laboratory supports Applied DNA’s growing global textile business in the Asia-Pacific region with expansion capability for other supply chains present in the region, such as fertilizer and pharmaceuticals. Officially opening on February 15, 2018, the Central Laboratory is strategically located in the state of Gujarat, an economic hub for the development and advancement of cotton, other textiles, fertilizers, petrochemicals and pharmaceuticals.Dr. Ila Lansky, a forensic scientist with over 11 years of forensic DNA experience, will direct the Central DNA Testing Laboratory. She currently oversees all aspects of forensic analysis, testing, authentication and reporting for all samples submitted, following the standard operating procedures established by Applied DNA’s New York forensic laboratories. The Central DNA Testing Laboratory is a high throughput laboratory, providing customers with accurate reports in a short turnaround time.
“This is an important opportunity for Applied DNA to bring our proven technologies to the heart of India’s textile industry, and share our impeccable standards and operational protocols,” said Dr. Lansky. “The laboratory will have the ability to process thousands of samples, serving our textiles customers in the region.”The Indian textile industry is currently estimated at approximately $135 billion USD and is expected to reach $230 billion by 2023 (IBEF 2017). It is home to such global textile brands and manufacturers as The Himatsingka Group and GHCL Limited. Additionally, India is home to the sixth largest pharmaceutical market in the world, with an expected value of $550 billion by 2020 (IBEF 2017).“Opening a lab in Gujarat has both strategic and practical importance for Applied DNA,” said Dr. James A. Hayward, president and chief executive officer of Applied DNA. “Our partnership with Himatsingka has proven remarkably successful, with uptake in the commercial ecosystem and endorsement by big box retailers. Adoption of our technologies by other textile companies is growing. Working closely with such India-based industry majors as Himatsingka and GHCL, we know Applied DNA’s value in enabling source-verified supplied chains and contributing the steady growth and ensured protection of the circular economy. It only makes sense for Applied DNA to have a facility where so many of our current and future partners are based.”

Large nuclear cardiology laboratory slashes radiation dose by 60% in eight years

Posted by fidest press agency su domenica, 7 maggio 2017

viennaVienna, Austria. A large nuclear cardiology laboratory has slashed its average radiation dose by 60% in eight years, according to new research presented today at ICNC 2017 and published in JACC: Cardiovascular Imaging.1,2 The study in over 18 000 patients shows dose reductions were achieved despite a large number of obese patients.
“There has been concern amongst the medical community and the public that the radiation from medical diagnostic tests could increase the risk of cancer,” said Professor Randall Thompson, a cardiologist at the Mid America Heart Institute, Kansas City, Missouri, US.
He continued: “Although the risk of harm from an individual nuclear cardiology test is very low – even very conservative estimates suggest only one in 1 000 extra patients would develop cancer 20 years later – the cumulative dose from multiple medical diagnostic tests may be a concern.” Medical societies advocate getting radiation doses as low as is reasonably achievable. There are ways to do this but surveys show that adoption of new technologies, which cost money, and new testing algorithms, which take more physician time, has been slow.
This study assessed the impact on radiation dose of modifying protocols and introducing new hardware (cameras) and post processing software in a large nuclear cardiology laboratory network in Kansas City.The study included the 18 162 single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) studies performed at all four of the Saint Luke’s Mid America Heart Institute nuclear cardiology laboratories from 1 January 2009 to 30 September 2016. SPECT MPI shows how well blood flows through the muscle of the heart and is primarily performed to diagnose the cause of chest pain or to help manage patients with known coronary artery disease. Protocols were modified by performing stress-only tests where possible, which saves the radiotracer dose from the rest scan. Stress and rest scans are still required in some patients since shadowing from body parts can look like a lack of blood flow and two scans can clarify the findings. Technetium tracers are now used instead of thallium 100% of the time at one-third of the radiation dose.Small field of view cameras which have advanced post processing, and a new generation of camera systems which are more sensitive and need less radiotracer injected into the body, have both been introduced. These camera systems are equipped with advanced processing which enhances the nuclear pictures and need less radiation or shorter image acquisition times. Professor Thompson’s laboratory focussed primarily on reducing the radiation dose.
The average radiation dose fell from 17.9 mSv in 2009 to 7.2 mSv in 2016 and the median dose (the 50th percentile) dropped from 10.2 mSv to 2.5 mSv. Professor Thompson said: “There was a dramatic lowering of the radiation dose with all of these concerted efforts. The average dose fell by 60% and the median dropped by 75%.” “The average dose had fallen to 5.4 mSv in 2012 but crept up as we’ve had more obese patients referred in whom we have to use the higher dose protocols,” he added. “But more than half of patients now are tested with a low-dose, stress-only test using the new technology, which is why the median dose of radiation has fallen so dramatically.”
The average background dose for people living in Europe and North America from radon underground and cosmic background sources is about 3 mSv a year. Medical societies consider higher and lower dose tests to be above 10 mSv and below 3 mSv, respectively. In 2010 the American Society of Nuclear Cardiology set a target of 9 mSv or less for the majority of tests. Professor Thompson said: “The majority of studies were in the high dose range back in 2009 and now most tests have a radiation dose that is about a third of the target. This is despite being referred a larger number of obese patients. In the last 2.5 years, 17% of patients have needed the large field of view camera as their average body mass index was 46 kg/m2 and they were simply too big for the small cameras.”He concluded: “By adopting contemporary protocols and technologies it is feasible to substantially lower radiation doses in nuclear cardiology in very large numbers of patients in real world clinical practice.”
