Phishing is probably the most common form of social engineering we see at the University. The emails will typically contain a statement that something is going to happen to your account if you don't act now, which usually involves clicking on a link to a page where you are requested to provide your username and password and sometimes more.
Another variant of phishing is Spear Phishing, which is targeted towards a specific individual or position likely to obtain confidential information or higher level credentials.
