Mobile App Penetration Testing in Singapore

Review the app and the backend it trusts. We test what is stored on the device, what the app can invoke, and whether the API independently enforces the user and tenant boundary.

Assess the client and the API together

A mobile finding rarely stops at the device. Data exposure, broken object authorization, and privilege escalation usually require the app and its backend to be reviewed as one flow, including the identities each hop trusts.

  • Keychain, Keystore, local files, caches, screenshots, and logs
  • Deep links, universal links, exported components, and WebView bridges
  • Certificate pinning, transport validation, and debug or backup exposure
  • Token lifecycle, refresh behavior, device binding, and API authorization

Use realistic identities and states

Tests run against approved builds and test accounts. We verify what changes when a user is suspended, logs out, switches tenants, changes device, or loses network connectivity, instead of treating a successful login as proof of correct authorization.

  • Cross-user and cross-tenant access attempts with synthetic records
  • Expired, revoked, and replayed tokens against backend endpoints
  • Sensitive actions that should require re-authentication or biometrics
  • Server-side enforcement when client checks are bypassed

Fit delivery to Singapore product teams

Scoping covers the app versions, backend environments, and regional data flows in scope. Technical findings can support internal MAS TRM, PDPA, or PCI DSS control work, but the engagement is a security assessment rather than a compliance certification or legal opinion.

  • Agree builds, accounts, test windows, and data handling before testing
  • Prefer staging or isolated tenants for state-changing cases
  • Report each issue with device, app version, identity, and affected data
  • Retest the corrected app and backend path before closure

Frequently Asked Questions

How is the Mobile App Pentesting schedule determined?

After a preliminary analysis where we map all targets, we calculate the man-day effort and present a finalized schedule.

Do you help remediate the vulnerabilities?

Absolutely. Our report includes specific remediation advice tailored to your tech stack and infrastructure.

Are reports legal compliance documents?

No. Our reports are not certifications or legal compliance documents; they are technical evidence packages prepared with recognized methodologies such as OWASP and NIST.
