Services

Assessments focused on real-world attack paths

Each engagement is designed to identify meaningful attack paths, platform-specific weaknesses, and implementation flaws within macOS and iOS environments.

Service

macOS Security Assessment

Offensive security assessment of macOS applications and system components, with an emphasis on:

Application trust boundaries and entitlement models
Inter-process communication surfaces (XPC, Mach services)
Privileged execution paths (launchd, helper tools, system services)
Installer and update mechanisms affecting system integrity
Local attack surfaces and privilege escalation conditions
Validation of exploitability and real-world impact
Service

iOS Application Security Assessment

Offensive security assessment of iOS applications, with an emphasis on:

Application protections and runtime behavior
Authentication flows, sessions, and trust assumptions
Local storage, Keychain usage, and sensitive data exposure
Interactions with backend APIs and remote services
Deep links, URL schemes, and inter-application surfaces
Validation of exploitability and real-world impact

Continuity

Continuous security validation

Ongoing validation after an assessment, focused on changes, regressions, and evolving attack surfaces over time.

Targeted follow-ups

Validation of specific components, fixes, or newly introduced functionality.

Regression testing

Verification that previously identified issues do not reappear after changes.

Evolving attack surface

Assessment of new features, integrations, or architectural changes over time.

Why Cryptum Labs

Assessments designed for real-world attack scenarios

Deep Apple platform expertise

In-depth understanding of macOS and iOS security mechanisms, trust boundaries, system services, and platform-specific attack surfaces.

Senior-level execution

All work is performed at a senior level, with no layered delivery or delegation.

Actionable reporting

Deliverables are designed for both decision-makers and technical teams, with clear and practical recommendations.

Research-informed assessments

Assessments are informed by reverse engineering, exploit development, and real attack techniques.

Approach

System-level offensive analysis

Assessments focus on how macOS and iOS security mechanisms interact, and how they can be abused in realistic attack scenarios.

Application and system boundary interactions
Privilege relationships and escalation paths
XPC services and trust validation mechanisms
Installers, updates, and deployment logic
Data flows across system and application components

Philosophy

Attack-driven security evaluation

Security is evaluated through realistic attack scenarios, focusing on how platform mechanisms can be abused rather than how they are intended to function.

Focus on realistic attack paths, not isolated weaknesses
Validation through controlled exploitation scenarios
Prioritization based on impact and exploitability
Research-informed analysis of platform behavior
Clear distinction between theoretical and practical risk

Deliverables

Reporting that supports action

Executive report
A concise risk-oriented document for decision-makers.
Technical report
