Once you know the original link, you can start looking for it in the application code.
There is also code in the code below that uses this link
There is also another variation on the use of the link in the code, using the example of the com.old.king application
They differ slightly, but there are differences. Both uses of the link will be used to create a YARA-rule.
Conclusion
The result of the analysis of applications of this type is the YARA-rule, which allows to accurately identify applications belonging to this type.
