A system, method, and computer-readable medium for detecting malicious computer code are provided. Instructions, such as HTML or JavaScript instructions may be received from a server, parsed, and executed. During execution of the instructions, one or more functions of a software application, such as a web browser, may be hooked, and an event object may be created for each called function that is hooked, resulting in a collection of event objects. Rules may be matched with event objects of the collection of event objects to detect malicious code. Attributes from the matched event objects may then be used to locate original malicious script or code injected into a web page.

Systems and methods for detecting malicious code

Systems and methods are provided for malware scanning and detection in a computing system. In one exemplary embodiment, the method includes launching, in a computing device of the computing system, a virtual machine, and launching, in the virtual machine of the computing device, an internet browser. The method also includes requesting, by the internet browser, data from a web page, and performing, using one or more analysis tools, analysis on the web page. In the method, performing analysis on the web page includes performing monitoring and recording of system application programming interface (API) calls, and creating software objects associated with the web page. The method also includes performing antivirus scanning of the software objects, de-obfuscating JavaScript associated with the software objects, and correlating data associated with the performed analysis to determine if the web page is a malicious web page.
