User accounts from your domain might have been compromised.
10月7日
The following is an automated security notification from Google about your
domain accounts.
It has come to our attention that some of your user accounts from your
domain: gapp.nthu.edu.tw might have been compromised.
The following users in your Google Apps domain appear to be affected:
coco0514@gapp.nthu.edu.tw
We have disabled the users in a way that they can be recovered by the admin.
Please follow the actions below in order to secure these users.
ACTIONS REQUIRED
1. To reset the user's password, follow the steps in this Help Center article:
https://support.google.com/a/answer/33319?hl=en
Inform the user of their new temporary password, and ask them to set a new
password. (It should not be a password used with any other sites.)
2. To help check whether their account might have been compromised, advise
users to:
Check for filters and forwarding rules so that email is not being
forwarded to suspect addresses.
Check to make sure their signature has not been changed.
BEST PRACTICES FOR SECURITY
As an administrator, you may also consider implementing additional security
features for your Google Apps domain:
1. Enrolling your domain in 2-step verification, which offers an additional
layer of user authentication:
