Android forensics: Investigating social networking cybercrimes against man-in-the-middle attacks

© 2016 IEEE. Cyber-Attacks are on the rise due to the increased usage of social networking application\u27s built-in Android devices via Wi-Fi connections, which has resulted in privacy issues. Several studies have been conducted to investigate Android phones, however, none of these have proposed a comprehensive Android investigation method, which begins with a Man-in-The-Middle attack and ending in a criminal investigation. The purpose of this research is to propose an Android forensics framework against such Wi-Fi attacks, using advanced forensic tools, such as the Cellebrite Universal Forensic Extraction Device and the Oxygen. This will assist the researcher to prove the suggested arguments in the following: 1. To implement guidelines for the forensic examiners, especially for those new in the field of forensics, and 2. To guide Android and social networking application developers to enhance the level of security. Furthermore, this study recommends the best data extraction methods designed for Android devices

NEW SECURITY PARADIGM – THE USE OF SOCIAL NETWORKS AS A FORM OF THREAT TO THE NATIONAL SECURITY STATE

Abstract Islamic State depends on the recruitment of foreign fighters to execute attacks in their home countries. This paper examines the influence of social networks such as Facebook, Twitter, and YouTube in the indoctrination and direction of young people into extremist and terrorist collectives. The study wholly depended on the qualitative analysis in unfolding the concerns related to social media and terrorism activities. After an in-depth exploration, the paper has proven that a good number of attacks are launched by homegrown terrorists who are self-radicalized and indoctrinated through YouTube videos, Facebook groups, and Tweets. Following this discovery, the researchers recommend collaboration between the social media owners and intelligence security agencies in combating terrorist activities online. The social media owners’ help in monitoring terrorists’ activities on their websites would thus help in improving the intelligence and the general security of the country

Longitudinal changes in IgG levels among COVID-19 recovered patients: A prospective cohort study.

ObjectivesTo quantify SARS-CoV2 IgG antibody titers over time and assess the longevity of the immune response in a multi-ethnic population setting.SettingThis prospective study was conducted in a tertiary hospital in Abu Dhabi city, UAE, among COVID-19 confirmed patients. The virus-specific IgG were measured quantitatively in serum samples from the patients during three visits over a period of 6 months. Serum IgG levels ≥15 AU/ml was used to define a positive response.Participants113 patients were analyzed at first visit, with a mean (SD) age of participants of 45.9 (11.8) years 87.5% of the patients were men. 63 and 27 participants had data available for visits 2 and 3, respectively.Primary outcomeChange in SARS-CoV2 IgG antibody titers over the visits.ResultsNo mortality or re-infection were reported. 69% of the patients developed positive IgG response within the first month after the onset of symptoms. The levels of IgG showed a consistent increase during the first three months with a peak level during the third month. Increasing trend in the levels of IgG were observed in 82.5%, 55.6% and 70.4% of patients between visit 1 to visit 2, visit 2 to visit 3, and from visit 1 to visit 3, respectively. Furthermore, about 64.3% of the patients showed sustained increase in IgG response for more than 120 days.ConclusionsOur study indicates a sustained and prolonged positive immune response in COVID-19 recovered patients. The consistent rise in antibody and positive levels of IgG titers within the first 5 months suggest that immunization is possible, and the chances of reinfection minimal
