Pharming
# The intention of pharming is the same as phishing..... to obtain personal information such
as usernames, passwords and bank details etc. Examples:
Pharming usually targets users of online banking or shopping websites.
# The way this is done however is slightly different. 'Pharmers' infect legitimate websites
with malicious code that will re-direct you to their bogus version of the website.
The bogus website will look very similar, or even identical, as the legitimate website.
This makes pharming very dangerous and difficult to detect.

Smishing (SMS phishing)
# Smishing is the same as phishing except the fraudulent messages are sent via text
messages (SMS) rather than emails. Examples:
For example:
You could receive a text message, sent to your mobile phone, which appears to be
from your bank and reports a problem with your account.
The text message would provide a web address or a phone number which you would
be asked to use in order to contact the bogus bank.
You would then be asked to provide your account details so that the problem could be
rectified.
Upon doing so, the fraudsters would use the account information to steal your cash. Smishing is 'phishing' over a mobile phone.
How to protect yourself against smishing:
1. Never give your bank details or passwords out over phone or text message.
2. Ignore text messages from people you don't know.
3. Report any phishing attempts to your mobile phone company.
