It utilizes full hypervisor integration to allow for high performance, scalable analysis that is resistant to detection and evasion techniques. VMRay's approach leverages the hypervisor to monitor all activity within virtual machines and detect advanced persistent threats and targeted attacks that other tools may miss.
Analysis of Field Data on Web Security Vulnerabilities
Base Paper Abstract:
Most web applications have critical bugs (faults) affecting their security, which makes them vulnerable to attacks by hackers and organized crime. To prevent these security problems from occurring it is of utmost importance to understand the typical software faults. This paper contributes to this body of knowledge by presenting a field study on two of the most widely spread and critical web application vulnerabilities: SQL Injection and XSS. It analyzes the source code of security patches of widely used web applications written in weak and strong typed languages. Results show that only a small subset of software fault types, affecting a restricted collection of statements, is related to security. To understand how these vulnerabilities are really exploited by hackers, this paper also presents an analysis of the source code of the scripts used to attack them. The outcomes of this study can be used to train software developers and code inspectors in the detection of such faults and are also the foundation for the research of realistic
vulnerability and attack injectors that can be used to assess security mechanisms, such as intrusion detection systems, vulnerability scanners, and static code analyzers.

The researchers developed a system called DroidRanger that uses permission-based filtering and behavioral analysis to detect both known and unknown malware. DroidRanger revealed 211 malicious apps total, with 32 from the official market and 179 from alternative markets. It also discovered a sophisticated zero-day malware with 40 samples, 11 of which were in the official market.
SYSTEM CALL DEPENDENCE GRAPH BASED BEHAVIOR DECOMPOSITION OF ANDROID APPLICAT...
This document discusses a proposed approach to map system-level behaviors of Android applications to Android APIs. The approach involves three steps: 1) obtaining an application's behavior through system-level tracking and symbolic execution, represented as System Call Dependence Graphs, 2) concurrently obtaining all Android APIs called by the application, and 3) mapping the System Call Dependence Graphs to the Android APIs based on system call entries and timestamps. This mapping could help identify potentially malicious applications trying to evade detection by avoiding direct use of Android APIs. The study shows this approach can effectively identify potential permission abuse with negligible performance impact.
Mitigating Privilege-Escalation Attacks on Android Report
This document summarizes previous work on mitigating privilege-escalation attacks on Android. It discusses how Android's open framework allows applications to potentially gain unauthorized access to data. It reviews common privilege-escalation attacks like confused deputy attacks and inter-app collusion. The document also summarizes existing security extensions that aim to prevent these attacks, but notes limitations in addressing confused deputy and collusion attacks specifically. It proposes extending reference monitoring at the kernel level in addition to the middleware to better prevent these types of attacks.

1. FlowDroid is a static taint analysis system that precisely tracks sensitive data flows in Android apps. It models lifecycles, callbacks, and asynchronous execution to handle Android complexity.
2. An evaluation on 39 benchmark apps found FlowDroid had higher precision and recall than commercial tools. It also detected all leaks in a vulnerable app with no false positives/negatives.
3. FlowDroid analyzes app bytecode, configurations, and models execution to detect data leaks from sources like contacts to sinks like advertising. Its context, field, object and flow sensitivities improve precision over prior work.
The Lazy Attacker: Defending Against Broad-based Cyber Attacks
Advanced Persistent Attacks (APTs) get most of the attention from the cyber security community because, as defenders, we want to be vigilant against the most insidious techniques. However, this unilateral mindset ignores a much less interesting reality.
Advanced Threat Protection - Sandboxing 101
The document discusses Blue Coat's Advanced Threat Protection solution, which uses a three-stage approach to block known threats, analyze unknown threats, and reduce the dwell time of latent threats. It focuses on the use of sandboxing to detect and analyze unknown threats through dynamic analysis in a virtual machine or emulation sandbox. Blue Coat's Malware Analysis Appliance utilizes a hybrid analysis approach with sandbox emulation and virtualization, behavioral detection patterns, and an extensible plugin architecture to analyze files and expose targeted attacks. The appliance is designed for enterprise scalability and integration with Blue Coat's ProxySG and Content Analysis System to enable blocking, detection, and analysis of threats across the security infrastructure.

ABSTRACT
Shoreline monitoring is important to overcome the problems in the measurement of the shoreline. Recently,
many researchers have directed attention to methods of predicting shoreline changes by the use of
multispectral images. However, the images being captured tend to have several problems due to the weather.
Therefore, identification of multi class features which includes vegetation and shoreline using multispectral
satellite image is one of the challenges encountered in the detection of shoreline. An efficient framework
using the near infrared–histogram equalisation and improved filtering method is proposed to enhance the
detection of the shoreline in Tanjung Piai, Malaysia, by using SPOT-5 images. Sub-pixel edge detection and
the Wallis filter are used to compute the edge location with the subpixel accuracy and reduce the noise. Then,
the image undergoes image classification process by using Support Vector Machine. The proposed method
performed more effectively and reliable in preserving the missing line of the shoreline edge in the SPOT-5
images.

ABSTRACT
Smartphones are used by billions of people that means the applications of the smartphone is increasing, it is out of control for applications marketplaces to completely validate if an application is malicious or legitimate. Therefore, it is up to users to choose for themselves whether an application is safe to use or not. It is important to say that there are differences between mobile devices and PC machines in resource management mechanism, the security solutions for computer malware are not compatible with mobile devices. Consequently, the anti-malware organizations and academic researchers have produced and proposed many security methods and mechanisms in order to recognize and classify the security threat of the Android operating system. By means of the proposed methods are different from one to another, they can be arranged into various classifications. In this review paper, the present Android security threats is discussed and present security proposed solutions and attempt to classify the proposed solutions and evaluate them.
