Default password verification - pass.sql

@c

Hi Friends

I am using pass.sql below scripts to check the default password in Oracle databases. I ran this scripts for some old database's as in the part of audit checking.

It shows the below username having default password, but SYS is not configured with default its having strong pwd. The database is migrated from other servers. How it happen? Please advice
