Although no action is needed, it is worth reviewing your password to make sure your account is as protected as possible.

IT Services is working on measures to mitigate against this kind of attack in the future. In the meantime, it is worth reviewing your password and other security measures to make sure your account is as protected as possible. 

You can set up two-factor authentication for your account for additional security, and monitor activity on your account to check for unauthorised activity.
