Analysis Method for Phishing SVG Files Described

Dynamic analysis reveals phishing SVG file secrets. In a recent diary entry, the author details a method for analyzing a phishing SVG file containing obfuscated JavaScript without engaging in static analysis. By utilizing a virtual machine disconnected from the Internet, the author opens the SVG in Microsoft Edge, accesses the developer tools, and switches to the Network tab. After entering a dummy password and clicking the Download button, the deobfuscated URL and payload are revealed. This approach allows for a safer examination of potentially harmful files while minimizing exposure to online threats.
