    • Misuse of API: If the API token is exposed, it could lead to unauthorized link manipulation.
Summary
  • Platform Purpose: A URL shortening and tracking system for Universitas Indonesia, designed to simplify link management and provide analytics.
  • User: Likely an administrator with full permissions to create, manage, and analyze links.
  • Data Volume: 5,202 links and over 5.7 million clicks have been recorded, making this a significant dataset for the university.
  • Importance of Data: Relevant for university operations, event management, and communication strategies. However, sensitive information like IPs and API tokens must be protected to avoid misuse.

Technical Details and System Features
1. Core Tools and Features:
  • Short URL Creation:
    • The system enables the creation of short URLs for long links. These URLs are displayed in the dashboard and include the following details:
      • Short URL
      • Original URL
      • Click counts
      • Creation date and time
      • The IP address of the user who created the link
  • Data Tracking and Analysis:
    • Click data and user information are logged through IP addresses.
    • Links can be sorted by date, clicks, or priority.
  • Bookmarklet Tools:
    • These tools allow users to shorten links directly from their browser without logging into the system.
  • API Integration:
    • The system provides an API for automated link creation and integration with other systems.
    • A Signature Token is used for secure requests to the system.
    • This feature is particularly useful for IT teams or software developers.

2. Identified Security Risks:
  1. Outdated Software Version:
    • The system uses YOURLS version 1.9.2, which is outdated and prompts for an update to the latest version.
    • Older versions may have unresolved security vulnerabilities.
  2. Exposure of API Token in Admin Interface:
    • The Signature Token is clearly visible in the second image.
    • This poses a significant risk as anyone with access to this token could exploit the API.
  3. Lack of IP Address Protection:
    • User IP addresses are stored and displayed in the system. If unauthorized individuals access this data, it could lead to a breach of user privacy.
  4. High Click Volume:
    • With over 5.7 million clicks recorded, the system is at risk of DDoS attacks or misuse of links if not properly secured.

3. Database Structure and Data Management:

    • Manage internal links and quickly shorten long URLs.
  • For Data Analysts:
    • Analyze link usage patterns (e.g., click counts and access times).
  • For Event Organizers:
    • Track user engagement with links related to forms, reports, and educational content.

Importance of Stored Data:
  • This data is highly valuable for the university as it includes:
    • User and student activities associated with the links.
    • Analytics on event attendance and resource usage.
    • API usage for integration with other systems.

Technical Summary
The YOURLS system used by Universitas Indonesia is a robust tool for managing short URLs and tracking analytics. With over 5,200 stored links and nearly 5.7 million clicks processed, it is a critical resource for data analysis and improving the university's communication strategies. However, immediate security improvements are required to safeguard user privacy and system integrity.
