Attack-driven security for macOS and iOS
Approach

Attack-driven approach for macOS and iOS

Security assessments are conducted from an offensive perspective, focusing on how macOS and iOS platform mechanisms can be abused in realistic attack scenarios.

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

Coverage

Attack surface driven

The assessment focuses on high-value attack surfaces within macOS and iOS environments.

Inter-process communication (XPC, Mach services)
Privileged execution paths (launchd, helper tools)
Installers, updates, and deployment logic
Application trust boundaries and entitlements
Local data storage and sensitive data exposure
Interactions with backend services and APIs

Positioning

Research-driven assessments

The approach is informed by ongoing research into macOS and iOS internals, enabling the identification of vulnerabilities that are often missed by conventional security assessments.

Focus

Depth over volume

The objective is not to maximize the number of findings, but to identify meaningful vulnerabilities with real impact on security.
