OUR METHODOLOGY

Attack Simulation Process

A systematic five-phase approach following PCI DSS guidelines and real-world threat actor TTPs to uncover every vulnerability in your payment infrastructure

1
Intelligence Gathering

Reconnaissance

We map your entire POS ecosystem including terminal makes/models, TMS infrastructure, network topology, payment processor integrations, and merchant ID configurations. Every potential attack surface is documented.

Key Techniques

  • Passive network reconnaissance
  • Terminal fingerprinting (Verifone, Ingenico, PAX, etc.)
  • TMS discovery and enumeration
  • Payment flow analysis
  • PCI DSS scope identification

Tools Used

Security Analysis

Vulnerability Assessment

Comprehensive scanning reveals misconfigurations, outdated firmware, weak encryption implementations, and known CVEs affecting your payment terminals, TMS platforms, and supporting infrastructure.

Key Techniques

  • CVE enumeration (POS-specific databases)
  • Firmware version analysis
  • TMS authentication and authorization testing
  • Configuration audit against CIS benchmarks
  • TLS/SSL cipher suite analysis

Tools Used

Attack Simulation

Exploitation

We simulate real-world attacks including card data interception, RAM scraping, terminal hijacking, and payment manipulation using techniques employed by actual threat actors.

Key Techniques

  • Man-in-the-Middle (MitM) attacks
  • Memory scraping simulation
  • Terminal firmware manipulation
  • Payment replay attacks

Evidence Collection

Data Analysis

Every finding is documented with cryptographic proof, risk scoring using CVSS 3.1, and business impact analysis. Evidence packages are prepared for PCI QSA review if needed.

Key Techniques

  • CVSS 3.1 scoring
  • PCI DSS requirement mapping
  • Business impact quantification
  • Attack chain documentation

Strategic Guidance

Reporting & Remediation

Comprehensive report with executive summary, technical deep-dives, and prioritized remediation roadmap. We provide hands-on support during the remediation phase and verify fixes with retesting.

Key Techniques

  • Executive summary for leadership
  • Technical remediation playbooks
  • PCI compliance gap analysis
  • Retest verification

THREAT INTELLIGENCE

Common Vulnerabilities

Real examples of critical security issues we frequently discover during POS assessments, with technical details and remediation guidance

CRITICAL

Cleartext PAN Transmission

CVSS Score

9.8

Description

Primary Account Numbers (PAN) transmitted without encryption over network. Attackers on the same network segment can capture complete card data using packet sniffing.

Technical Evidence

HTTP traffic analysis revealed PAN data in request body: {"card":"4111111111111234","cvv":"123","exp":"12/25"}

Remediation

Implement P2PE (Point-to-Point Encryption) from card swipe to processor. Deploy TLS 1.3 for all internal communications.
