Critical Findings

Key Takeaways

  • Client – one of India's leading broking and capital markets institutions, serving millions of investors through a large digital and enterprise ecosystem.

  • Problem – needed to validate whether its people, processes, and technology could withstand a determined real-world attacker rather than a conventional security assessment.

  • What Payatu did – conducted a full-scope, black-box red team assessment across physical security, cloud, enterprise infrastructure, identity, and employee attack surfaces.

the challenge

Why the client called us in

Security reports showed compliance, but they didn't answer the most important question: Could a determined attacker compromise the organisation? The client engaged Payatu to validate its resilience through a realistic, end-to-end red team assessment spanning people, processes, physical security, and enterprise infrastructure.

  • Emulate advanced real-world attack scenarios
  • Measure detection and response effectiveness
  • Deliver evidence-based improvements to cyber resilience

scope of engagement

What was in scope

  1. External reconnaissance and attack surface assessment
  2. Internal network and Active Directory security assessment
  3. Cloud infrastructure and enterprise identity testing
  4. Physical intrusion and office security validation
  5. Real-world phishing and social engineering campaigns

Our Approach

How Payatu ran the engagement

01

Discovery
Conducted open-source intelligence (OSINT) and external reconnaissance to map the client's attack surface, identify exposed assets, and profile potential attack vectors.

02

Initial Access
Simulated real-world intrusion techniques through phishing, external exploitation, and physical intrusion attempts to establish an initial foothold within the organization.

Key findings

What we found

CRITICAL
Active Directory compromise
Misconfigurations and privilege escalation paths resulted in complete domain compromise.
CRITICAL
Credential theft
User credentials and authentication tokens enabled sustained access and lateral movement.
