Avoiding Phishing Scams

The term "phishing" refers to a type of scam where someone sets up a page that masquerades as a site you are familiar with, in order to trick you into entering your login information.

Suppose your bank's web site is example.com, and you get an e-mail from them that links to a page on their site, prompting you to log in. The page looks legitimate. But before you enter any information, check the location bar in your browser (the place where you would type in an address).

Here is a checklist for verifying that you're really looking at a page on example.com

  1. After the http:// or https:// in the address, find the first slash.
  2. If there is no slash, it's a scam.
  3. If there is a slash, make sure it's a forward slash (/) and not a backslash (\).
  4. If what stands immediately before that slash is anything other than example.com it's a scam.
  5. If it does say example.com, make sure that the next thing before that is either:
    • a period (dot) or
    • the two slashes that follow http.

Examples

http://www.example.com
BAD - This address has no trailing slash and takes advantage of a bug in Internet Explorer.
http://www.example.com.index.html.example.org/?trick=sneaky
BAD - This is a page on example.org, not on example.com.
http://www.example.com:index.cfm@example.net/something=phishy
BAD - This is a page on example.net, not on example.com.
http://www.example.com\index.cfm:do@example.net/what=this
BAD - Notice that the first slash is actually a backslash.
http://www-example.com/do=something&very=secure
BAD - A a dot is a domain separator, but a hyphen is not, so www.example.com and www-example.com are two entirely unrelated domains.
http://www.example.com/index.php?do=something&when=now
GOOD - This is a page on example.com
http://example.com/index.php?do=something&when=later
GOOD - This is a page on example.com
