Local data storage often holds critical credentials, configuration files, and sensor data on the device itself. When attackers can manipulate or extract this data, they can spoof devices, hijack sessions, or escalate privileges—undermining both security and user trust.
Local Data Storage Security Testing evaluates how your application or embedded system protects its data at rest, ensuring robust controls against tampering, unauthorized access, and weak storage schemes.
Tests Performed in Local Data Storage Assessments
Device Spoofing
We attempt to manipulate or forge device identifiers (e.g., hardware IDs, stored tokens) in local storage, verifying whether such tampering allows an attacker to impersonate a trusted device on your network.
Identity Tampering
This test checks if user or device identities—such as locally stored UUIDs, certificates, or credentials—can be altered to assume another user’s privileges or bypass access controls.
Pairing Attacks
We evaluate the security of pairing or provisioning workflows, testing whether captured or injected pairing keys and tokens stored locally can be reused to connect malicious devices as “trusted” endpoints.
Session Hijacking
We inspect how session cookies, tokens, or keys are stored on the device and attempt to extract or replay them, confirming that local storage protections (e.g., encryption, secure flags) prevent unauthorized session takeover.
Brute Force
This test assesses whether locally enforced passcodes, PINs, or account lockouts are vulnerable to automated guessing attacks due to weak rate-limiting, predictable patterns, or cleartext storage of hashes.
Device Impersonation
We verify if attackers can inject malicious firmware images or credentials into local storage—allowing a counterfeit device to masquerade as legitimate hardware during communications with backend systems.
Weak Identifier
We analyze stored identifiers (MAC addresses, UUIDs, serial numbers) for predictability or reuse. Weak or static identifiers enable tracking, cloning, or unauthorized access across devices.
Insecure Crypto
This test examines the strength and implementation of any encryption or hashing applied to stored data—looking for weak algorithms (e.g., MD5), improper key storage, or lack of authenticated encryption that could expose plaintext.
Backdoor Accounts
We search for hidden or undocumented user accounts, credentials, or debug logins stored on the device that bypass standard authentication checks.
Default Credentials
We check whether out-of-the-box usernames and passwords remain unchanged in storage—allowing attackers to log in with vendor-supplied credentials before any customization.
