In the ever-evolving landscape of cybersecurity, tools that enable security analysts and system administrators to efficiently analyze and understand potential threats are invaluable. Highlighter, a freeware utility developed by FireEye, is one such tool that aims to streamline the process of examining files for suspicious content. This article will explore the key features of Highlighter, its target audience, supported platforms, installation process, and how to effectively utilize the tool to enhance cybersecurity efforts.

What is Highlighter?

Highlighter is a free utility designed by FireEye, a leading cybersecurity company, to assist security analysts and system administrators in analyzing files for potential threats. The tool provides users with three distinct views of the file being analyzed: a text view, a graphical full-content view, and a histogram view. These views offer unique insights into the file's content and structure, enabling users to identify and highlight suspicious keywords, remove lines containing "known good" content, and visually recognize usage patterns that may indicate malicious activity.

Key Features

Highlighter offers several key features that make it a valuable tool for cybersecurity professionals:

  1. Text View: This view allows users to highlight interesting keywords and remove lines containing "known good" content, streamlining the analysis process by focusing on potentially malicious content.

  2. Graphical Full-Content View: The graphical view displays the entire content and structure of the file as an image that can be dynamically edited through the user interface. This feature provides a comprehensive overview of the file, making it easier to identify suspicious patterns or anomalies.

  3. Histogram View: The histogram view displays patterns in the file over time, revealing usage patterns that may not be apparent in other text viewers or editors. This metadata can be extremely useful in identifying malicious activity or trends.

Who Can Use Highlighter?

Highlighter is primarily designed for security analysts and system administrators who are responsible for maintaining the security of their organization's computer systems and networks. However, the tool's user-friendly interface and intuitive features make it accessible to anyone with a basic understanding of cybersecurity concepts and a need to analyze files for potential threats.

Supported Platforms

Highlighter is a Windows-based application and supports the following versions of the Windows operating system:

  • Windows 2000

  • Windows 2003

  • Windows XP

  • Windows Vista

  • Windows 7 (32-bit and 64-bit)

It is important to note that Highlighter may not be compatible with later versions of Windows or other operating systems such as macOS or Linux.

Highlighter is a powerful and user-friendly freeware utility that can significantly enhance the capabilities of security analysts and system administrators in identifying and mitigating potential cybersecurity threats. By providing multiple views of a file's content and structure, Highlighter enables users to efficiently analyze files and make informed decisions about their potential risk. As cybersecurity continues to be a critical concern for organizations worldwide, tools like Highlighter will remain essential in the ongoing effort to safeguard digital assets and maintain a secure computing environment.
