How to Execute a Red Team Operation Against Financial Institutions

November 27, 20234 min read

Executing a Red Team operation, particularly against financial institutions, requires a detailed plan, sophisticated tools, precision, and a thorough understanding of cybersecurity and financial regulations. Red Teams simulate the tactics, techniques, and procedures (TTPs) of real-world attackers, with the goal of identifying security weaknesses before malicious actors can exploit them.

I. Planning Phase

  • Objective Setting
    • Define clear objectives for the Red Team operation.
    • Establish what success looks like and determine the scope of the operation.
  • Team Assembly
    • Select a team with a diverse skill set including penetration testers, social engineers, physical security specialists, and cybersecurity experts.
    • Ensure that the team has no prior knowledge of the security systems in place at the financial institution to maintain a realistic testing environment.
  • Legal and Compliance Review
    • Obtain written permission from the financial institution’s senior management.
    • Review relevant laws and regulations to ensure the operation will not violate any legal or compliance standards.
  • Intelligence Gathering
    • Perform reconnaissance to gather information about the financial institution.
    • Identify potential entry points for the digital and physical infrastructure.
  • Tool Selection
    • Choose appropriate tools and methods for the operation, which might include social engineering kits, penetration testing software, and lock-picking tools.

II. Execution Phase

  • Initial Breach
    • Attempt to gain initial access through various methods, which may include spear-phishing, exploiting public-facing applications, or using compromised credentials.
  • Privilege Escalation
    • Once inside the system, attempt to escalate privileges to gain greater access to sensitive information or critical systems.
  • Lateral Movement
    • Explore the network to understand how systems are connected and to identify high-value targets.
    • Continue to move laterally within the network to reach these targets without being detected.
  • Persistence
    • Establish methods to maintain access within the environment for potential long-term operations.
  • Exfiltration
    • Test the ability to remove data from the network without triggering data loss prevention measures.
  • Covering Tracks
    • Conduct operations in a way that mimics regular user behavior to avoid detection.
    • Remove evidence of the Red Team’s presence in the system to test the institution’s ability to identify and trace back activities.

III. Reporting Phase

  • Data Analysis
    • Review the data collected during the operation to identify the exploited vulnerabilities and assess the overall security posture.
    • Examine the effectiveness of security controls, incident response capabilities, and security team awareness.
  • Developing Recommendations
    • Create a comprehensive report with detailed findings of security weaknesses and potential improvements.
    • Suggest realistic and actionable steps for remediation based on best practices and industry standards.
  • Presentation to Stakeholders
    • Present the findings to the financial institution’s management and key stakeholders.
    • Focus on the potential impact of the identified vulnerabilities and the value of taking corrective actions.

IV. Post-Operation Phase

  • Remediation Verification
    • After the institution has implemented remedial actions, verify that changes have been executed properly and that vulnerabilities are effectively mitigated.
  • Retesting
    • Optionally, conduct a follow-up engagement to ensure that fixes are holding and that no other issues have been introduced in the course of remediation.
  • Continuous Improvement
    • Discuss the benefits of incorporating regular Red Team exercises into the institution’s security program.
    • Advocate for ongoing security training and awareness programs to improve the organization’s security culture.

Important Note: The entire process should be executed with the utmost respect for ethics and legal boundaries, ensuring that the security testing does not disrupt the financial institution’s normal operations or compromise any customer data.
