Phishing can generally be defined as non-legitimate email you receive that tries to get you to provide the sender something personal. The sender is generally "fishing" for something from you, typically, one of the following...
info (including personal info, login credentials, or alternate contact info, e.g. cell #)
money (including gift cards)
What are some elements that make up phishing email?
It could be in the form of an html-based email with a login page embedded.
It could be something as simple as someone emailing you requesting you to send them info directly.
And sometimes, the sender might have first created an email address, like a gmail address, that looks similar to one you might already know... but not exactly the same.
Or it might be a masqueraded sender address. See the Spoofing (Masquerading)/Spear Phishing section below.
A phishing email might have a link to a login or info request page.
The above are just some examples of characteristics of phishing emails.
(Later in this page, we will provide you instructions for reporting phishing email to the appropriate groups.)
Be Wary...
It is very important that you examine all incoming email to make sure it comes from a legitimate source.
Your mail client should provide you a way to look at full mail or message headers so you can see if what you think is a legit address in the From: part of your message is actually the real address the sender is sending from.
If you're unsure about an email, you should look up the person's email address off an official website (my.jh.edu, etc.) and use the looked-up address to contact the email originator to confirm the email request. Remember, these spammers might simply change even one character in their own email address from an email address you might already recognize.
If your email has a link to a web page, the text for the link you see in your email may not be where the link actually takes you. Examine the link carefully. If you're at a computer, you might be able to hover your pointer over the link to see its true URL.
Also, look for spelling or grammatical errors in an email. Sometimes, those could indicate that the email is not from a legitimate source.
Spoofing (Masquerading)/Spear Phishing
Spoofing or Masquerading is when someone sends an email and it appears to come from someone else. You you could receive spoofed/masqueraded email in the form of a phishing email. Please see above for info on phishing email.
Spear Phishingextends the masquerading, as spear phishing is a type of phishing spam where a spammer sends email that appears to be from someone you know/trust, but is actually from the spammer.
In the case of spear phishing, the spammer tries to get you to send them information (financial, etc.), as you might think you're actually sending it to the person you know/trust (and you're really not.)
Spear Phishing is a very dangerous type of email, and it's easy to fall prey to it. It has become a common personal information-fishing tactic. And... it's also a very easy thing for a spammer to do.
Spammers can make the From: address in your email look like any name or email address, like that of your trusted friend, family member, co-worker, etc. However, the actual e-mail was sent by the spammer. Examining the full mail headers for your email (different methods for each email client), can help you determine the actual sender's (spammer's) email address. (And it's also possible that the spammer's email address you see in the headers might not actually belong to the spammer, but rather another email address the spammer has stolen.)
If you receive email that looks like it comes from someone you know, but the message content seems suspicious in some way, examine the mail carefully, including the mail headers for the actual sender's email address, to be sure it's legitimate. If you receive email asking for personally identifiable information, financial info, login credentials, etc., be wary, and make sure you are replying to the legitimate audience.
If you are not sure if the email is legit, contact the "sender" by an alternate means, e.g, by phone (a phone number you know is legit) or send a separate email to that individual (do not just click reply on the suspicious email) using an email address you know for that individual.
If You Receive Phishing/Spoofing Email...
If you receive phishing/spoofing email , especially if it's requesting you to log in to the JHU login page (or to other pages that request you to login) or requests your cellphone number or asks for a gift card or wants to know your availability, please be wary of it, and if you think it's not legit, do not click on any included links located in that phishing mail!
Instead... (and please read the below options carefully.)
...if the mail you received is specifically a Phishing email that looks like it came from an @cs.jhu.edu email address
If you receive a Phishing email that looks like it came from an @cs.jhu.edu email address, we want to know about that, regardless of whether you received the email at your own @cs.jhu.edu or @jhu.edu email address. So, in this instance, please forward the Phishing email (including any mail headers, if possible, by forwarding itas an attachment), to support@cs.jhu.edu so that our CS IT Support Team can examine it and take proper action.
However...
If the Phishing email you received does not look like it came from an @cs.jhu.edu email address, then please see the below two options to determine who to report the Phishing email to.
...if you receive Phishing/Spoofing email at your @jhu.edu, @jhmi.edu or other non-@cs.jhu.edu (but still JHU-related) email address
If you receive spam (including phishing, etc.) email at your @jhu.edu (or @jhmi.edu, @jh.edu, etc.) email address directly (and is not from an @cs.jhu.edu email address, or if you don't forward your CS email to your @jhu email), you can visit JHU's How-to page for reporting spam As part of the process, you'll want to forward that email (including any mail headers, if possible, by forwarding it as an attachment), to spam@jhu.edu (and perhaps make the Subject Line say SPAM), so that JHU can examine it and take proper action. If you're not sure if the email is legitimate, mention that in your correspondence with JHU IT as well. If you haven't heard back from JHU in a reasonable amount of time, please open a trouble ticket with JHU IT.
NOTE: Phishing mail received at your non-CS email address and that did not originate from an @cs.jhu.edu address does not need to be reported to CS IT (i.e,. support@cs.jhu.edu)
...if you receive Phishing/Spoofing email directly at your @cs.jhu.edu email address
If you receive the spam/phishing email directly (i.e., not forwarded from your @jhu.edu address) at your CS email address, or... if you think the email originated from an @cs.jhu.edu email address, please forward it (including any mail headers, if possible, by forwarding itas an attachment), to support@cs.jhu.edu so that our CS IT Support Team can examine it and take proper action.
