Please be aware that there has been a recent influx of malicious emails being sent from Google Docs. The email doesn’t look quite right, but anyone who clicks through arrives at a login screen that looks almost indistinguishable from the same screen you’d see if someone actually invited you to a Google Doc. This phish works because it tricks the user into granting permissions to a third-party application. This is the future of phishing, it is becoming ever more sophisticated.
Phishing attempts which seek to get you to click on bad links don’t necessarily have to follow this pattern. It is important that you are diligent before opening emails, especially if they have strange links and/or attachments.
