GEN001475 - The /etc/group file must not contain any group password hashes.

Information

Group passwords are typically shared and should not be used. Additionally, if password hashes are readable by non-administrators, the passwords are subject to attack through lookup tables or cryptographic weaknesses in the hashes.

Solution

Edit /etc/group and change the password field to an exclamation point (!) to lock the group password.
