Missing secure obfuscation - APK
Description
It is possible to obtain source code of the application because it has not been obfuscated using a secure mechanism. This could allow an attacker to understand the inner workings of the application or get technical or sensitive information.
Impact
Get technical or sensitive information from the applications source code.
Recommendation
Obfuscate the applications source code at deploy time with tools like: https://github.com/ClaudiuGeorgiu/Obfuscapk in its strongest configuration.
Threat
Unauthorized attacker from Internet network with access to the APK.
Expected Remediation Time
⌚ 120 minutes.

Compliant code
The code is correctly obfuscated using relevant secure tools
//Rename Obfuscation method
private void calculatePay(a b){
while(b.c()){
b.a(true);
c.a();
b(c);
}
}
Non compliant code
The source code was not obfuscated before compiling
//Code before obfuscation
private void calculatePay(SpecialList clientGroup){
while(clientGroup.HasMore()){
clientGroup.getNext(true);
client.updatePay();
makePay(client);
}
}
