Unexpected e-mail messages that have you click on links, open attachments, or disclose sensitive information can be seriously malicious.
You should remember that all sections of an email you receive, including the sender, can be manipulated to look however an attacker wants it to.
UniSA prevents the majority of spam and phishing from reaching staff and students but not all unwanted emails can be stopped and it is important that users can identify and learn how to deal with to these emails.
Spam is unsolicited and/or bulk emails usually with a commercial focus on promoting or selling products. These can be a nuisance but don't need to be reported, blocking senders or unsubscribing from services are an effective control.
Phishing is a malicious email that attempts to gain some benefit from your interaction, such as responding or clicking a link. Websites that contain malware or other payloads don't require any interaction besides you opening the website. Any response informs attackers they've sent to a legitimate email address which can lead to further use of your email, such as trying to login as you.
The two main types of phishing emails are credential submission (getting you to enter your credentials into a website) and impersonation attempts (pretending to be someone you know to convince you to do something).
Staff and students should be aware of:
- Unsolicited emails, including sender or content, unrelated to your role
- Senders who appear to be a UniSA staff member but the email doesn't come from an @unisa.edu.au address
- Use of scare tactics or threats to perform an action
- Links to a website to enter credentials (particularly Outlook, OneDrive, or other Microsoft service)
If you're suspicious of an email you SHOULD NOT click links, open attachments, or respond. The email should be forwarded as an attachment (Ctrl + Alt + F) to the IT Help Desk (ithelpdesk@unisa.edu.au). However, if you have interacted with the email please follow the recommended process:
- If an attachment was opened:
- Disconnect your computer from the network by unplugging network cables and/or turning off WiFi; AND
- Call IT Help Desk IMMEDIATELY on (08) 8302 5000.
- If credentials were submitted by clicking on a link within the email:
- Call the IT Help Desk IMMEDIATELY on (08) 8302 5000 to change your password.
- If you replied to the email:
- Please stop any further communication
- Call the IT Help Desk IMMEDIATELY on (08) 8302 5000 to change your password.
