v4.7.4.3 suspicious
5.0
Medium Risk

Assemblyline 4 - Automated malware analysis framework

🤖 AI Analysis

Final verdict: SUSPICIOUS

The package exhibits a moderate level of risk due to potential command injection vulnerabilities from the use of shell=True in subprocess calls. While there are no clear signs of malicious intent, further scrutiny is warranted.

  • High shell risk due to use of shell=True
  • Moderate network and obfuscation risks
Per-check LLM notes
  • Network: Network calls include standard HTTP and FTP interactions which could be legitimate depending on the application's functionality.
  • Shell: Use of shell=True in subprocess calls can lead to command injection vulnerabilities and should be scrutinized carefully.
  • Obfuscation: The use of base64 decoding and json.loads suggests data might be encoded for transport or storage, which is common but could indicate obfuscation.
  • Credentials: No clear patterns indicating credential harvesting were detected.
  • Metadata: The maintainer has only one package, which might indicate a new or less active account, but no other suspicious activities were flagged.

💡 AI App Starter Prompt

Use this prompt to build a project with assemblyline 
Create a fully-functional mini-application called 'MalwareAnalyzer' using the Python package 'assemblyline', which is an automated malware analysis framework. This application will serve as a simplified version of a malware analysis tool for educational purposes. The application should allow users to upload suspicious files and receive a report detailing the file's behavior, including any malicious activities detected during analysis.

Steps to follow:
1. Set up the environment by installing the required packages, including 'assemblyline'.
2. Develop a user interface where users can upload files for analysis. For simplicity, you may use a command-line interface (CLI).
3. Implement functionality within the application to submit the uploaded file to the Assemblyline server for analysis.
4. Retrieve the analysis results from the Assemblyline server and present them in a structured format to the user.
5. Enhance the application by adding features such as saving the analysis report to a local file, displaying the analysis status in real-time, and providing options to filter the report based on severity levels.
6. Ensure the application handles errors gracefully, such as when the file upload fails or the Assemblyline server is unreachable.
7. Document the steps to set up the application and its usage, along with any assumptions made during development.

Features to consider implementing:
- Real-time progress updates while the file is being analyzed.
- A summary section in the report highlighting key findings.
- Options to analyze files in different formats (e.g., executables, scripts, documents).
- Integration with a simple database to store and retrieve historical analysis reports.

Utilize the 'assemblyline' package's core functionalities, such as submitting files for analysis and retrieving results, to achieve the goals of the application. Explore the documentation and available examples provided by the package to understand how to interact with the Assemblyline server effectively.
