Desktop Application Penetration Testing (Electron, thick client)
We test desktop and thick-client applications, including Electron builds, for renderer sandbox escapes, IPC boundary flaws, insecure local credential storage, and privilege boundaries a local attacker can cross.
Testing Checklist
Every engagement covers these critical security areas.
Testing Methodology
A structured, repeatable process that ensures thorough coverage and actionable results.
Build and Configuration Review
Inspect the packaged application for Node integration exposure, contextIsolation and sandbox settings, DevTools accessibility, and whether the renderer loads remote content in production builds.
IPC Boundary Testing
Map the inter-process communication surface between renderer and main process, then test whether the renderer can invoke privileged operations it should not reach.
Local Storage and Credential Handling
Examine how authentication tokens, session state, and configuration are persisted on disk, and whether they survive tampering by a local user.
Privilege Boundary Assessment
Establish what a low-privilege local account can read, modify, or exfiltrate, including host configuration relevant to a user with console or shell access.
Client-Side Logic Review
Test validation, state machines, and decision logic that runs on the device rather than server-side, where a determined user controls the runtime.
Reporting and Remediation
Deliver findings tagged with CWE identifiers and scored with CVSS v3.1, mapped to OWASP DASVS verification requirements, with reproduction steps and fixes specific to the framework in use.
