PHISHER? | Or Just a Spoofer?

Spoofer. Smaller eyes, shorter teeth. Darker fur.
Often less dangerous than a Phisher, but...
It may help to look at the attached photos to appreciate the differences between Spoofers and Phishers.

They have some things in common - like two long teeth on both the upper and lower jaws with which they can rip your throat out and then proceed on a more leisurely basis to the rest of what's left of you.

Both spoofers and phishers are e-thieves.

It pays, therefore, to learn their M.O.'s and take the steps recommended below to prevent yourself being damaged by either of them.

They say good judgment comes from experience... Experience comes from bad judgment. But let's move on.

Spoofers

Spoofers change the apparent sender details on an e-mail and fool you into thinking they are someone they are not. This could just be for fun, or more likely it could have an ulterior motive of getting you to believe that the person they are pretending to be is in trouble. So you may get an email that looks like it is from your classmate Fred, who explains he is in Paris and he lost his wallet and could you please wire cash immediately to Western Union to be picked up by Fred's friend Maham Xuru. Anyone asking you to send money to Western Union is immediately suspicious, because that is a favorite way of getting money.
Phisher. Longer teeth, wider eyes. Longer fur, lighter shade
of color. Does not have your interest at heart.

Phishers

Phishers design emails to try to get you give up sensitive information.

They are more dangerous because if their design works, you may not realize you are giving them access to sensitive information.

Sensitive means passwords that enable e-thieves to remove money from your bank account directly... or charge something to your credit card.

Spoofers and Phishers Work in Teams

The two predators can work together.

You may get an email that looks like it's from someone you know, and then gets emails designed to coax you to give access to passwords to opening your accounts.

Spotting Spoofers

Spoofers are clever at hiding, but there are ways to spot them.

One technique they are using is to include the logos of the companies they are pretending to be. Once upon a time, they would just send an email saying "This is the AOL E-mail Memory Department - you have exceeded your 2 Gigabyte limit - click on the link below to expand your memory or we will close your account." Now spoofer is more likely to include the AOL logo and other indications that this is a genuine warning.

One of the cleverest techniques is to have the e-mail come from the Fraud Prevention Department, or include a link marked "Unsubscribe".  It would be cute or funny if their purpose wasn't so deadly.

Return e-mail addressed may include slightly altered names that substitute a different domain ending or a different letter in the name of the organization - a zero instead of an O, for example.

AOL and other ISPs have been showing headers in e-mails, or allowing this as an option, which makes it easier to spot spoofers.

The worst case is when a spoofer manages to take over a computer. That happened to me. I basically had to buy another computer. Good judgment comes from experience. Experience comes from bad judgment.

Spotting Phishers

Phishers are easy to identify through the trail that they lay out for you. They want you to come to a place where they can jump up at you and finish you off with a lunge at your throat.

Essentially, phishers want to make money by charging a thing, or things, to your account that you will never see, or by simply taking money out of an account.  Spoofing is a stop on the way to achieving their purpose.

They want the phishee to provide personal information through a reply to an e-mail or through filling out a fork on a website.

Protecting Yourself

Before following a link, hover your cursor over it and check that the address matches the one you think you are going to or sending to. Here are the questions that should be going through your mind:
  • What Are They Asking for? Be careful about any email that asks for your social security number or tax identification number, your bank account information, credit card number, PIN number, credit card security code, your mother's maiden name, your birthplace or your favorite pet's name.
  • Is the English Grammatical? Poor grammar or typographical errors may mean the e-mail is being tranlasted automatically from another language or is sent by people for whom English is not their first language.
  • Does the Return Address Look Genuine? If the "received from"or "reply to"  for the e-mail looks strange, start worrying. Most e-mail programs let you look at the source of the e-mail. 
  • Does the Website Look Real? Some phishers set up spoof websites. When in doubt, reply directly to a known e-mail address.  
  • Does the E-mail Address Look Real? Some phishing e-mails include a link that looks as though it will take you to a real account, but it is really a shortened link to a completely different website. If you hover over the link with your mouse when viewing the message in your e-mail client, you often can see the underlying false website, as a pop-up or in the browser status bar.
  • Do They Offer a Chance to "Unsubscribe"? Spammers often use the "Unsubscribe" button to  create a list of valid e-mail addresses for nefarious purposes.

Spoofed Again - Looking for Advice

A warning note from CERN.
On Thanksgiving Day I was spoofed again for the first time in two years. (Previously I was spoofed/phished using Norton antivirus software on a Vaio PC with Internet Explorer; SONY no longer services these  Vaios.)

A spoof occurs when a malicious hacker gets email addresses from your contact list and sends emails that look as thought they are coming from you. The hacker is "phishing" for someone to click a URL in order to get begin getting access to another computer or to persuade the recipient to send money.

A favorite spoof is an appeal to you to wire money to someone on your email list who is stranded in a foreign country like Nigeria and needs instant cash to buy a plane ticket home. You will be repaid as soon as the sender returns. Yeah, sure.

Someone got access to my AOL contact list and sent emails to a couple of hundred people saying in my name: "I recommend this - click here." I myself have received many such emails and by now I know enough not to click on them. Another clue to recipients of the spoof in my name was that the email address attached to the sender was a name that looked nothing like mine. But still, I am sorry this happened and I am taking steps to prevent a recurrence.

Ever since I purchased a Mac, I have not had a virus problem, so this is a first on the new computer. Someone who received one of the spoofs sent me an email sympathizing and suggesting I change my ISP password and have a complete scan of my computer with the Kaspersky antivirus program or another one that works. This program costs money to buy and more money to keep updated. So I sought advice. Here's what I did:
1. I called AOL right away and changed my password. It is now a unique password that I use for no other purpose.
2. At the same time, I changed my security question and answer. It is one that could not be guessed from any bio.
3. I was advised by AOL tech support to check whether I am getting properly covered by McAfee. Then I discovered that AOL's McAfee download is not compatible with Mac computers and operating systems or on Safari. It requires Windows and Explorer or Firefox.
4. So then I went to JustAsk.com and asked for advice on an anti-virus program that works with Macs. (On JustAsk you rate the answer and you pay a fee for the answer if you are satisfied.) I was told to use AVG, a free Dutch-based antivirus program with an office in San Francisco. AVG got rave reviews in 2006-2010. I did this and the program searched 1.3 million files and found four Trojan horses, which have all been removed and the files in which they appear have been deleted. The Trojan horses were all in AOL messages that had these subject lines: "service completed", "payment advice", "invoice" and "payment".
5. Then I read a review that says that AVG in 2014 is not so good any more. Bummer.
So now I am looking for advice again from anyone who has faced any of these problems and dealt with them satisfactorily. I started to load OS X 10.10 (Yosemite) and I see that it has created a host of problems for some people. The one-star rating is the most common rating of the new software. I am holding off on upgrading to the new Mac operating system.
