Criminals (hackers) send out spoof/fake emails to thousands of random email addresses with the intent of convincing valid UCalgary faculty or staff members to respond to their requests.
Some emails are obviously a scam, while others are more subtle. Many have poor grammar or spelling, but all have been very effective in acquiring user IDs and passwords. Criminals usually do this with the intent of aquiring security details, getting you to share that information verbally, or by clicking a link to another website that the criminal has created.
Your information is then recorded and can be used to gain access to your account. The result could be fraudulent emails being sent from your email account, access to your computer files and/or accessing your private information to commit identity theft.
