A systematic five-phase approach following PCI DSS guidelines and real-world threat actor TTPs to uncover every vulnerability in your payment infrastructure
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
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Comprehensive scanning reveals misconfigurations, outdated firmware, weak encryption implementations, and known CVEs affecting your payment terminals, TMS platforms, and supporting infrastructure.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
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
Tools Used
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

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
