Security assessments for macOS and iOS

Cryptum Labs provides macOS and iOS security assessments focused on real attack paths, platform internals, and exploitability analysis.

In certain engagements, assessments may extend to targeted offensive scenarios involving macOS systems where relevant to the application or platform context.

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

Optional

Continuous security validation

Ongoing validation following an assessment, focused on changes, regressions, and newly introduced attack surfaces.

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.
