How to Identify JavaScript Attacks

Rolling Meadows, IL, USA (30 November 2016)—New ISACA guidance will help cyber security professionals identify a form of attack that enriches hackers by utilizing JavaScript code to redirect users to advertisements that generate revenue for the hacker.


The white paper, “Incident Response: Obfuscated JavaScript and Evil Adware Recognition,” analyzes a web server malware sample from to describe a real-world attack that compromises a website content management system (CMS) with JavaScript code. The attack analysis pinpoints traits associated with redirection attacks.


The guidance includes figures highlighting network traffic captures, requests for JavaScript files, embedded redirect code and other elements associated with the attack.


The guide examines how analysis of network traffic captures helped an organization identify exploitation vectors. Malware analysts identified a variety of web requests to download and execute malicious JavaScript. Understanding that the malicious code and redirection to nefarious servers are indicators of web-server exploitation aided the analysts in recognizing characteristics of the attack, and can be useful in web-server evaluations.


The white paper is part of the guidance and tools that global business technology and cyber security association ISACA provides cyber security professionals and their organizations through its Cybersecurity Nexus (CSX).


“While cyber attacks resulting in the theft of personal or financial information are well-documented, nefarious actors also are capable of more subtle attempts in pursuit of financial gains,” said Christos Dimitriadis, Ph.D. CISA, CISM, CRISC, chair of ISACA’s Board of Directors and group director of Information Security for INTRALOT. “This guidance will allow cyber professionals and their organizations to be more vigilant in guarding against attacks on CMS JavaScript code.”
