To prevent unauthorized use of devices through app modification.

This book provides an understanding of cases of damage from unauthorized app modifications and countermeasures.

In recent years, the digitalization of devices has progressed in various fields, and the trend of realizing diverse functions through apps is spreading in the manufacturing industry. Consequently, there has been an increase in damages such as the decline of corporate profits and credibility due to the sale of illegally modified apps resulting from cracking (the act of unauthorized analysis and alteration), as well as the leakage of proprietary technologies and know-how contained in these apps. When apps that interface with company devices are modified, and pirate apps that enable unintended functions circulate, the safety of the devices themselves becomes a concern. Even with devices that utilize new technologies like drones, cracking of the apps can lead to the theft of proprietary technologies and the sale of imitation products, resulting in a wide range of potential damages. One of the reasons for this is that information related to cracking and easy-to-use illegal tools for beginners are readily available on the internet. The security product "CrackProof" aims to prevent such cracking damages to apps.
