Technical Capabilities

Powered by static taint analysis, 3rd party dependencies fingerprinting and vulnerability analysis, dynamic instrumentation and novel backend scanning capabilities, Ostorlab leads the way by providing the most advanced vulnerability detection capabilities.

Configuration Analysis

Configuration analysis checks the settings of features like debug mode, backup mode, network security policy and framework-specific settings, like Cordova whitelist to detect unsafe values that introduce vulnerabilities or lower the application's security.

Static Taint Analysis


Taint analysis is a powerful capability that evaluates all execution paths within the application to detect vulnerable patterns. Taint analysis is capable of detecting vulnerabilities caused by unsafe settings, like the use of weak cryptographic ciphers, or vulnerabilities caused by accepting untrusted input without validation.

3rd Party Vulnerability Detection


Powered by a fingerprinting engine that understands all major frameworks like Cordova, Ionic, Xamarin or React Native and all popular package management systems, like Gradle, Cocoapods, npm or nuget, Ostorlab is capable of detecting outdated vulnerable dependencies. Ostorlab also maintains its own vulnerability database providing curated vulnerability data, correcting and listing unreported vulnerabilities.

Dynamic Analysis

Dynamic analysis monitors the application's behavior on a real device. Using debug-powered analysis, Ostorlab dynamic instrumentation supports the latest version of Android and iOS and provides false-positive-free results. Dynamic analysis also uses a monkey-tester (software) to interact with the application and maximize coverage during testing. Monkey-tester is capable of heuristically identifying login forms, checkout menu or shipping addresses.

Behavioral Analysis

The behavioral analysis lists the application attack surface and injects it with attack input to detect vulnerabilities. These vulnerabilities range from SQL injection to memory corruption. Ostorlab behavioral analysis implements an advanced evolutionary approach that provides high coverage within the application.

XSS Detection


While XSS vulnerabilities still plague web application, it still impacts multi-platform mobile applications as well as multi-platform backends. Ostorlab XSS detection uses powerful polyglot payloads to detect DOM and reflected XSS vulnerabilities and uses fuzzing to find postMessage XSS vulnerabilities.

Backend Vulnerability Analysis

Backend analysis uses API requests collected during dynamic analysis to crawl the backend server, and fuzz it for vulnerabilities. Ostorlab backend analysis is tailored for mobile application and understands API serialisation protocols like REST, GraphQL or Protobuf. Backend fuzzing uses a novel approach powered by machine learning, providing advanced detection capabilities with a very low number of requests.
