Avoiding scams - another example

The below message got by my SPAM filter and landed in my email inbox: (BTW, I normally do not allow automatic display of images in emails, or even open suspicious emails, but captured the below image for educational purposes, after doing some research.)


The email looks like it is from a social networking site, asking me to join/accept a new friend. This is not uncommon - we often get/send messages to people inviting them to join Facebook, LinkedIn, or some other social networking site.


However, the email immediately looked fishy because (1) I've never heard of "Jhoos" and was suspicious of it. (2) I didn't know the person whose name was listed in the email who supposedly "wants to be my friend." I did a search on that person's name in my email inbox and we were once both cc'ed on a message. (3) It's funny there is both a "Yes - Accept" and "No - Reject" button. Why would I click No to reject a friend on a site that I don't even belong to (instead of just deleting the email.)

Reminder 1 - Don't click on links if you're not sure of the site it is taking you to, especially if it is given to you by someone you don't know!
Reminder 2 - Just because an email says it was sent to you by John Smith does not mean it was sent by John Smith. Even if it is (supposedly) your best friend asking you to join some site, I'd double check with your friend, and double check the site (if I haven't heard of it.)

I did a google search on "jhoos" and supposedly it is a free online dating service. BUT, I also found many other google results (such as McAfee's SiteAdvisor site) that WARN AGAINST that site, which will install things on your computer without you knowing, send "invitations" to everyone in your address book (it asks you to enter in your email password so that you can supposedly connect with other friends), and perhaps other things. I didn't try it out myself, but seems pretty clear to me the social networking/dating thing is a front.

Reminder 3 - Don't ever give your email account password to anyone!
I know some sites will ask you to enter your email account info, and I really dislike it. (Facebook has it as a feature for inviting/connecting with friends.) Sure, maybe it's convenient. But do you really wanna give that much access to your account to some stranger? It's like giving someone the keys to your house. Not a good habit.

Don't get scammed on Facebook

Imagine this scenario: Mr. Stranger guesses/steals your password, hijacks your Facebook account, and sends messages to all your friends that you are in trouble, stuck in some foreign country, and need money to be sent to you immediately. Some of your friends may fall for it and actually send money to Mr. Stranger trying to help you.

This kind of Facebook scam has happened many times, and a couple friends I know have even been affected (but were smart enough not to believe it.)

A few basic principles to remember:
- Any person contacting you online (through Facebook, email, instant messaging...) may not be who you think it is. It could be an impersonator.
- Use a good password that others can't easily guess. Some suggestions on how to choose a password here.
- Don't enter your password into fake (phishing) look-alike sites or pretend emails, which are just waiting for you to put in your personal info.

Avoid phishermen. Don't get tricked!


According to various sources (such as Symantec), spam accounts for 90% of all email. Pretty crazy, huh? Luckily my email providers have pretty good spam filters, so I don't have to deal with junk mail too much. (BTW, looks like spam makes up about 45% of my mail, so I guess I'm doing pretty well..?)

Whether you have a good spam filter or not, it is a useful skill to be able to tell whether an email is "real" or "fake." There are some people who send emails that look like they are from some trustworthy entity (such as your bank), in order to try to get you to enter sensitive information, such as your password, credit card number...
This is called "phishing." Don't get caught! Think twice before clicking on any link or entering in sensitive information.
