There is a reason that Phishing is the first scam on this web site, scammers
need to do this in order to start the next stage of the scam. If they can't
'Phish' your information out of you then, in most cases, they can't scam
you.
Phishing
What is phishing (And yes, the spelling is correct)? It is simply a scammer
trying to get information out of you in order to use it for there own evil
purposes.
Phishing is usually the start of a number of scams, including ebay, Paypal
and all credit card scams - the reason for this is simple, scammers need your
information in order to access your accounts.
All identity theft scams also start with phishing.
Phishing can be done a number of ways; the most common methods are emails
and phone calls.

First we'll look at emails.
You will receive an email (and if you have an email for more than a year
then you WILL receive one) which will be made to look like it comes from a
legitimate source (e.g ebay, Paypal, your local bank).
These emails are very well made and are made EXACTLY the same as a real email
would look. Ironically the ebay fake email even has a link to the security
section of ebay, just like the real ebay email does!
These emails will ask for you to update your personal details and you must
give them quickly. The email goes on to tell you that if you don't update your
details then your account is suspended. This is done in order to pressure you
to do it fast.
If you click on the link in these emails then you will be taken to a web
site that looks just like the real thing (i.e a fake ebay email will take you
to a fake ebay site, a fake paypal email will take you to a fake paypal
website).
If you then enter your account name and password you have just given it to the
scammers.
The best way to avoid these scams is to simply hit the delete button when
you receive the email.

Phone calls
It could happen to you so be ready.
The next time you receive a phone call from your bank (not
when you ring them) there is one thing you MUST do - ask to ring them
back.
Wether you tell them that you are busy and will ring back in five minutes or
you simply tell them that you are going to ring back in order to verify their
identity - it doesn't matter, you MUST ring them back as that is the
only way to verify they are real.
If they give you a phone number to call you back on then you can be 99% certain
that it isn't a scam, scammers will NEVER give you any information to lead you
back to them. If you are really paranoid then double check the phone number
before you ring them back.
If it is a scammer ringing you they attempt to get you to verify who you
are. They ask for your name, address, social security number (if you are in
the USA) or bank account numbers (in Australia); that's all the information
they need.
Now they will tell you that your account is under investigation and that you
are not to use this account until an internal investigation is completed, they
say that this will take 3 days.
In those 3 days scammers can not only clean your account out but can also
get loans from major lending organisations; in Australia there was case where
AUS$250,000 (US$190,000) was taken out in loans within 5 days.
You won't know about these loans until the paperwork arrives at your doorstep
in order for you to make your first repayment.
