CAPE (Configuration, Automation, Payload Extraction) Sandbox is an automated malware analysis system designed to execute and analyze suspicious files within isolated environments. It's a fork of the popular Cuckoo Sandbox, offering a user-friendly web interface and a REST API for integration with other security tools. CAPE Sandbox automatically collects comprehensive data about the malware's behavior, including system calls, file modifications, network traffic, and registry changes. This information is then presented in detailed reports, allowing analysts to quickly identify malicious activity and understand the malware's capabilities. CAPE is not just a static analysis tool; it actively observes the malware in a controlled setting. More information on what is CAPE can be found here.

Key Features

CAPE Sandbox boasts a wide array of features that make it a valuable asset for malware analysis:

  • Automated Analysis: Streamlines the analysis process, eliminating the need for manual execution and monitoring of suspicious files.

  • Detailed Reporting: Provides comprehensive reports containing detailed information about the malware's behavior, including system calls, file modifications, network activity, and registry changes.

  • Web Interface: Offers a user-friendly web interface for submitting files, managing analysis tasks, and viewing reports.

  • REST API: Enables integration with other security tools and platforms, allowing for automated analysis workflows.

  • Customizable Environments: Supports various operating systems and software configurations, allowing analysts to tailor the analysis environment to specific malware samples.

  • Network Analysis: Captures and analyzes network traffic generated by the malware, revealing communication patterns and potential command-and-control servers.

  • Signature Generation: Facilitates the creation of YARA rules and other signatures based on the analyzed malware, improving detection capabilities.

  • Dynamic Analysis: Focuses on observing the runtime behavior of the malware in a controlled environment.

  • Open Source: Being open source allows for community contributions, ensuring continuous improvement and customization. A guide to setting up CAPEv2 sandbox can be found online.

Use Cases or Applications

CAPE Sandbox can be applied to various security tasks and scenarios:

  • Malware Identification and Classification: Quickly identify and classify unknown malware samples based on their behavior.

  • Threat Intelligence Gathering: Extract valuable information about malware capabilities, targets, and communication patterns for threat intelligence purposes.

  • Incident Response: Analyze malware involved in security incidents to understand the scope of the compromise and develop effective remediation strategies.

  • Vulnerability Assessment: Identify potential vulnerabilities exploited by malware.

  • Security Research: Conduct in-depth malware research to understand emerging threats and develop new detection techniques.

  • Automated Analysis Pipelines: Integrate with SIEMs or other security platforms to automatically analyze suspicious files and URLs detected in the network.

  • Phishing Analysis: Analyze suspicious attachments or URLs in phishing emails to identify malicious content and protect users. Building an automated malware sandbox can improve the speed of analysis.

What is Unique About CAPE Sandbox?

CAPE Sandbox stands out due to its combination of features and open-source nature. While other sandboxing solutions exist, CAPE offers a balance of powerful analysis capabilities, ease of use, and customization options. Its active community and regular updates ensure that it remains a relevant and effective tool for tackling the latest threats. Further, the open-source nature allows security teams to customize the environment to match their specific needs and infrastructure, a major advantage over closed-source solutions. The REST API allows for seamless integration into existing security workflows. You can find the CAPE tool here.

Who Should Use CAPE Sandbox?

CAPE Sandbox is a valuable tool for a wide range of security professionals:

  • Security Analysts: To analyze suspicious files and URLs, understand malware behavior, and generate threat intelligence.

  • Incident Responders: To investigate security incidents, identify compromised systems, and develop remediation strategies.

  • Threat Hunters: To proactively search for and identify hidden threats within the network.

  • Malware Researchers: To conduct in-depth analysis of malware samples and develop new detection techniques.

  • Security Engineers: To integrate malware analysis into security infrastructure and automate threat detection.

  • Managed Security Service Providers (MSSPs): To offer malware analysis services to their clients. One can refer to this guide to build CAPEv2.

Supported Platforms & Installation

CAPE Sandbox is primarily designed to run on Linux-based systems. Detailed installation instructions and documentation are available on the CAPE Sandbox GitHub repository: https://github.com/kevoreilly/CAPEv2. The installation process involves setting up the necessary dependencies, configuring the analysis environment, and installing the CAPE Sandbox software. The documentation provides step-by-step guidance for both basic and advanced configurations. The github repository is available at CAPE's Github.

Pricing

As an open-source project, CAPE Sandbox is free to use and distribute. This makes it an attractive option for organizations of all sizes, particularly those with limited budgets. However, organizations may need to invest in hardware and personnel to support the deployment and maintenance of CAPE Sandbox. Also, there is the option to obtain a commercial license from affiliated companies to access enhanced features and support capabilities. Documentation can be found at readthedocs.

Short Summary

CAPE Sandbox is a powerful and versatile open-source automated malware analysis system. Its key features include automated analysis, detailed reporting, a user-friendly web interface, and a REST API for integration. It's suitable for a wide range of use cases, including malware identification, threat intelligence gathering, and incident response. While it is free to use, implementing and maintaining the software requires technical expertise. CAPE Sandbox offers a cost-effective and customizable solution for organizations seeking to enhance their malware analysis capabilities. It is important to read the license terms and conditions from CAPE's Github before installing the software. Finally, due diligence in sandbox selection, like this article, is always a good idea.
