Handling your compromised account

Compromised Accounts Overview 

This article provides guidance to staff, students and users if an unauthorised person has gained access to your account. When someone that is not you gains access to your credentials (i.e., username, passwords), your account is considered to be compromised. This means that unauthorised persons are able to use your credentials to pose as you, and the privacy of your data and others is at risk. AIT monitors email traffic, and if our systems find a suspicious pattern or behaviour, we will notify you that your account has been compromised. If you receive this notification, or if you notice that you are unable to log into your email account, the sections below provide some steps that you can immediately take to protect your information. Additionally be aware of any unprompted Authenticator notifications you may receive on your device as that may indicate somebody is trying to access your account.

Remember legitimate messages from AIT will never ask for your credentials. If you are unsure please contact us immediately on 0115 9170 197.
