A hardcoded password is used.
Password manipulation can be risky, for instance if passwords are stored in plain in a property file. Moreover, passwords stored as program constants expose to the risk of inferring the password by simply looking at the binary executable of the code. This checker identifies situations when password manipulation is done in an unsafe way.

Avoid storing passwords in property files and use encrypted files instead. Do not use program constants for passwords, store them in encrypted files instead.
