different methods. On the one hand, we have launched known attacks against a machine running our scripts; on the other hand, we have deployed that machine on the Internet, next to a high interaction honeypot during two months. For those attackers that have targeted both machines, we can verify if our

JavaScript is a browser scripting language that allows developers to create sophisticated client-side interfaces for web applications. However, JavaScript code is also used to carry out attacks against the user’s browser and its extensions. These attacks usually result in the download of additional

A script-based attack framework is a new type of cyberattack tool written in scripting languages. It carries various attack scripts targeting vulnerabilities across different systems. It also supports fast development of new attack scripts that can even exploit zero-day vulnerabilities

authentication.) Some of the common attack types reported today, such as SQL injection and cross-site scripting, involve such subversion of legitimate access privileges. In this paper, we present a new approach to strengthen policy enforcement by augmenting security policies with information about

, however, and attacks such as the Samy and Yamanner worms have exploited filtering weaknesses. This paper proposes a simple alternative mechanism for preventing script injection called Browser-Enforced Embedded Policies (BEEP). The idea is that a web site can embed a policy in its pages that specifies

into downloading malicious JavaScript code from an intermediate, trusted site. In this case, the malicious script is granted full access to all resources (e.g., authentication tokens and cookies) that belong to the trusted site. Such attacks are called cross-site scripting (XSS) attacks.

into different zones of different sizes and then features from each of these zones are extracted in various directions using gabor filters. Script is then determined by using SVM classifier. The experimental tests carried out in the field of Gurmukhi and English Script recognition show that the proposed

Cross-site Scripting (XSS) attacks in web applications are considered a major threat. In a yearly basis, large IT security vendors export statistics that highlight the need for designing and implementing more efficient countermeasures for securing modern web applications and web users. So far, all

We present a practical protection mechanism against SQL injection attacks. Such attacks target databases that are accessible through a web frontend, and take advantage of flaws in the input validation logic of Web components such as CGI scripts. We apply the concept of instruction

JavaScript has been exploited to launch various browser-based attacks. Our previous work proposed a theoretical framework applying policy-based code instrumentation to JavaScript. This paper further reports our experience carrying out the theory in practice. Specifically, we discuss how
