Web Application Security

One-time project / long-term partnership

Web applications are often the primary attack surface for modern businesses. We conduct deep, exploit-driven assessments of authentication flows, session handling, access controls, and business logic to uncover real attack paths that put your data and users at risk.

Why it matters: A single unvalidated business logic flaw can grant attackers access to customer data, payment processing, or sensitive operations—often without detection.

What We Attack

  • Authentication & session mechanics (credential reuse, fixation, bypass)
  • Access control enforcement (broken function level, IDOR, privilege escalation)
  • Business logic flaws (race conditions, workflow bypass, state manipulation)
  • Integration points (third-party auth, SSO, OAuth token misuse)
  • Client-server trust boundaries and API contract violations

Engagement Approach

  • Target Mapping: Identify all entry points, authentication schemes, and user roles
  • Control Validation: Test each control's resilience to bypass, injection, and abuse
  • Business Logic Testing: Simulate real attacker workflows to exploit multi-step flows
  • Impact Verification: Confirm that discovered flaws yield access to sensitive data or operations
  • Retest & Evidence: Provide reproducible PoCs and remediation verification

Compliance & Standards

  • GDPR / NIS2: Data protection and availability validation
  • PCI DSS: Payment data and cardholder environment controls
  • ISO 27001 / SOC 2: Access control and incident response readiness
  • OWASP Top 10: Industry-standard vulnerability taxonomy
Real-world impact

A retail platform that trusts user-supplied IDs in API requests can leak customer order histories and personal data. A SaaS application with weak session tokens can be hijacked mid-session. A financial web app with race condition flaws can be manipulated to double-spend balances. We find these and provide proof before attackers do.

Typical timeline

Scope definition (1–2 days), reconnaissance and attack surface mapping (2–3 days), controlled exploitation (3–5 days), PoC validation (1 day), reporting and retest (2–3 days). Total engagement typically 2–3 weeks for moderate scope.

API Security Testing

One-time project / long-term partnership

Modern architectures rely on APIs as the backbone of business logic and data flow. From public REST endpoints to internal service-to-service communication, each API is an attack surface. We systematically identify and exploit authorization gaps, token misuse, and trust boundary weaknesses to expose data and access paths that attackers seek.

Why it matters: APIs are frequently targets for automated attacks, unauthorized data access, and lateral movement. A single broken endpoint can expose customer databases, internal secrets, or cross-tenant data.

Attack Surface Coverage

  • Endpoint enumeration (public & hidden routes, versioning, undocumented paths)
  • Authentication bypass (missing auth, weak token validation, credential reuse)
  • Authorization flaws (BOLA, horizontal/vertical privilege escalation, ACL abuse)
  • Parameter tampering (resource IDs, pagination, filtering, sorting)
  • Token misuse (JWT claim injection, oauth flow bypass, token reuse across scopes)
  • Data leakage (verbose error messages, metadata exposure, timing attacks)
  • Rate limiting and abuse (brute force, enumeration, resource exhaustion)

Methodology

  • Discovery: Map all endpoints, methods, parameters, and response structures
  • Authentication Analysis: Test token generation, validation, and refresh flows
  • Authorization Testing: Validate resource access controls across roles and tenants
  • Business Logic Validation: Test multi-step workflows, edge cases, and state manipulation
  • Proof of Concept: Generate reproducible HTTP requests and responses showing impact
  • Retest & Closure: Verify remediation and confirm controls are enforced

Compliance Alignment

  • GDPR / NIS2: Data access validation and availability assurance
  • DORA: Financial operational resilience and ICT criticality assessment
  • ISO 27001 / PCI DSS: Access control, encryption, and incident response
  • OWASP API Security Top 10: Industry-specific API attack taxonomy
Example findings

A fintech API that accepts user-supplied account IDs in requests leaks customer balances and transaction history. A multi-tenant SaaS API returns data from the wrong tenant due to missing authorization checks. A mobile app's API endpoint allows password reset with only an email, enabling account takeover. We find these through systematic, exploit-driven testing.

Why API testing is different

APIs require different testing approaches than web UIs: no browser protections, programmatic access, less logging, and faster attack iteration. We use API-specific tools and techniques to uncover real exploitability, not just theoretical risks.

Cloud & Identity Attacks

One-time project / long-term partnership

Cloud environments introduce new attack surfaces: IAM policies, role assumption, workload identity, and service-to-service trust boundaries. Misconfigurations in these areas can grant attackers access to entire environments, databases, and sensitive systems. We map and exploit real privilege escalation paths in your cloud infrastructure.

Why it matters: A single overpermissioned IAM role or exposed metadata service can lead to account takeover, data exfiltration, or infrastructure compromise. Many cloud breaches start with identity abuse.

Cloud Attack Vectors

  • IAM misconfiguration (overpermissioned roles, assume-role trust abuse, cross-account access)
  • Metadata service exploitation (EC2, GCP, Azure Instance Metadata endpoints)
  • Service principal / managed identity abuse (Kubernetes, serverless, databases)
  • Workload identity federation (trust boundary bypass, token exchange attacks)
  • Cloud storage exposure (public buckets, ACL misconfiguration, bucket policy bypass)
  • Credential exposure (API keys, tokens, secrets in logs, configs, environment variables)
  • Cross-account and cross-subscription lateral movement
  • Privilege escalation through role chaining and trust relationships

Testing Approach

  • Identity Mapping: Document all IAM roles, service principals, and trust relationships
  • Privilege Analysis: Identify excessive permissions and privilege escalation paths
  • Metadata & Token Testing: Attempt exploitation of cloud-specific identity mechanisms
  • Lateral Movement: Test paths from compromised workload to sensitive resources
  • Data Access Validation: Confirm unauthorized access to databases, storage, and secrets
  • Evidence & Remediation: Provide PoCs demonstrating real exploitability and remediation steps

Compliance & Governance

  • DORA: Cloud criticality assessment and ICT risk management
  • GDPR / NIS2: Data protection in shared cloud environments
  • ISO 27001 / CSA STAR: Access control and cloud-specific security controls
  • Cloud CAF & FedRAMP: Architecture review and identity governance
Real-world scenarios

An EC2 instance with overpermissioned IAM role can be compromised to assume admin roles and access all company data. A Kubernetes service account in a container can query metadata endpoints to obtain credentials for adjacent workloads. A misconfigured assume-role trust allows an attacker to assume a production role from a staging account. We uncover these chains and quantify the impact.

Why cloud identity testing is critical

Cloud environments centralize identity and access control. A single broken trust relationship or overpermissioned principal can expose your entire infrastructure. Unlike on-premises systems, cloud misconfiguration is often invisible until it's exploited.

Infrastructure & AD Testing

One-time project / long-term partnership

Active Directory and network infrastructure are critical trust boundaries for enterprise security. Misconfigurations, weak controls, and poor segmentation enable attackers to move laterally, escalate privileges, and establish persistence. We test your network defenses with controlled, exploit-driven attack scenarios.

Why it matters: Many breaches involve AD compromise, credential theft, and lateral movement. A single weak password, delegation misconfiguration, or unpatched system can grant attackers domain admin privileges and access to all resources.

Attack Surface & Techniques

  • Active Directory enumeration and abuse (Kerberoasting, AS-REP roasting, delegation attacks)
  • Credential harvesting (LSASS dumping, SAM extraction, Mimikatz testing)
  • Lateral movement validation (pass-the-hash, pass-the-ticket, Zerologon)
  • Privilege escalation paths (token impersonation, token delegation, UAC bypass)
  • Network segmentation testing (VLAN hopping, routing abuse, firewall bypass)
  • DNS & DHCP poisoning and abuse
  • Persistence mechanisms (scheduled tasks, WMI, Golden Ticket creation)
  • Domain trust exploitation (external trusts, forest transits, SID history)

Engagement Methodology

  • Asset Discovery: Identify domain controllers, servers, endpoints, and network topology
  • AD Enumeration: Map users, groups, delegation, trusts, and privilege pathways
  • Controlled Exploitation: Test Kerberos flows, credential reuse, and privilege escalation in lab or staging
  • Lateral Movement Validation: Demonstrate real paths from compromised endpoint to sensitive systems
  • Segmentation Testing: Validate network controls and access restrictions
  • Persistence & Detection: Test attacker persistence techniques and your detection capability

Regulatory Alignment

  • NIS2: Critical infrastructure resilience and incident response
  • DORA: ICT operational risk in financial services
  • ISO 27001 / SOC 2: Access control, audit logging, and incident management
  • MITRE ATT&CK: Technique mapping for defense prioritization
Engagement scope

We typically test from both external network access (DMZ, VPN) and internal endpoints. Scope includes AD abuse, credential theft, lateral movement, and privilege escalation. Testing is performed in staging or controlled lab environments where possible, with careful coordination to avoid business impact.

Why this matters for your business

AD compromise is the most common path to enterprise breach. A single weak point—an overpermissioned service account, an unpatched system, or a delegation misconfiguration—can lead to complete domain takeover. We validate your defenses and help you prioritize remediation.

Automotive & Embedded Security

One-time project / long-term partnership

Modern vehicles and embedded systems are software-intensive and connected. Firmware flaws, weak authentication, and insecure communication protocols can enable remote attacks on vehicle functionality, safety-critical systems, and passenger data. We conduct specialized security assessments of ECUs, CAN networks, wireless protocols, and OTA update mechanisms.

Why it matters: Vehicle safety and data protection are intertwined. Vulnerabilities in infotainment, telematics, or control systems can affect safety, privacy, and brand reputation. Regulatory requirements (ISO 21434, WP.29) mandate security assessment throughout the product lifecycle.

Automotive Attack Surface

  • ECU firmware analysis (reverse engineering, binary hardening, crypto evaluation)
  • CAN network protocols (message injection, spoofing, diagnostics abuse)
  • Wireless interfaces (BLE, cellular, WiFi, TPMS, keyless entry)
  • OTA update mechanisms (signature validation, rollback protection, secure boot)
  • Infotainment & telematics (app sandbox, data encryption, API security)
  • Gateway & communication security (CAN/FlexRay bridges, authentication, encryption)
  • Supply chain & third-party components (library vulnerabilities, vendor code review)
  • Vehicle-to-Infrastructure (V2X) and cloud backend integration

Assessment Methodology

  • Hardware Analysis: Teardown, component identification, and debug port enumeration
  • Firmware Extraction & Analysis: Extraction, reverse engineering, crypto evaluation, hardening assessment
  • Protocol Testing: CAN, diagnostics (UDS), wireless protocol security
  • Functional Testing: Safety-critical system manipulation and exploit validation
  • OTA & Update Security: Signature validation, rollback protection, secure boot
  • Data Security: Encryption, PII handling, secure deletion
  • Threat Modeling & Risk Assessment: SOTIF and ISO 26262 alignment

Compliance & Standards

  • UNECE WP.29: UN regulation for vehicle cybersecurity and OTA updates
  • ISO 21434: Automotive cybersecurity engineering and risk management
  • ISO 27001 / TISAX: Information security and automotive supplier trust framework
  • ISO 26262 / SOTIF: Functional safety and safety of the intended functionality
Example vulnerabilities

An ECU firmware lacks secure boot, allowing arbitrary code execution. CAN network accepts unauthenticated messages, enabling brake or throttle manipulation. OTA updates are not cryptographically signed, allowing downgrade attacks. Keyless entry protocol is vulnerable to relay attacks. Telematics API exposes vehicle location and owner information. We assess these systematically.

Why automotive testing is specialized

Automotive security requires specialized knowledge: embedded systems, automotive protocols (CAN, UDS, ISO-TP), hardware analysis, and safety-critical considerations. We combine cybersecurity expertise with automotive domain knowledge to provide assessments that meet regulatory requirements and protect vehicle safety and data.
