This example is pretty flagrant in many respects. The grammar is very bad (note the first sentence is not even a complete sentence). It does not come from a Stanford address (what is telkomsa.net?) It is signed "Standford". The email is addressed to "info@cs.stanford.edu". Even if that is a legitimate address, it would clearly go to a very large number of people, but the email itself suggests that the individual recipient's account has been compromised. And, of course, the email includes a link to click where the recipient is supposed to "update settings". Do not trust links like this, especially when they do not even pretend to go to a stanford.edu site.
