Fake "Rodriguez shared an important docs with you" message is a phisher scam
Many Caltech email users received a message today with the subject line "Rodriguez shared an important docs with you" and a message stating "Rodriguez Ricardo (firstname.lastname@example.org) Shared you a secure document to review and sign. "Contract .pdf"". These messages are fakes and the fraudulent site they link to is blocked from campus. It is always a good practice to examine a link received in email to see where it goes. Most mail clients will let you do this if you mouse over, but don't actually click, on the link. On a mobile device, press-and-hold will typically also display where a link goes.
