Abstract: Systems and methods for securing hybrid applications for computing devices are described. According to the present subject matter, the system(s) implement the described method(s) for building and execution of secure hybrid applications. During build of the hybrid application, the disclosed method may incorporate identifying of at least one non-native file of the hybrid application, generating a primary Unique Identifier (UI) associated with the at least one non-native file, and storing the generated primary UI as a part of the hybrid application to form a secure hybrid application. During execution of the secure hybrid application the disclosed method may incorporate identifying of at least one non-native file of the secure hybrid application, generating a secondary UI associated with the at least one non-native file, extracting primary UI stored in the secure hybrid application. The system/method may further implement determining whether the generated secondary UI is different from the extracted primary UI.
