15. PHISHING
Phishing is the attempt to obtain confidential user information by
camouflaging as a trustworthy entity in an electronic communication,
usually in the form of an e-mail or instant messenger. This is where URL
spoofing comes into play. Electric communications substituting as
messages sent from companies such as eBay, PayPal, Youtube and online
banks are a common camouflage for scam artists.
The infected e-mails or messages usually direct a user to enter confidential
information into an illegitimate website, where the attacker can easily gain
access the users details.

16. CYBER STALKING
Cyber stalking is literally harassing and following another
person online. Social networking sites open up many doors for
cyber stalking.

17. URL SPOOFING
URL spoofing is when one website poses as another website for malicious reasons. This
assail involves the cloning of a legitimate web page, such as a bank site. The cloned site is
created on another server under the control of the scam artist and is created to deceive
users into believing they are on a trusted site. Users then proceed using passwords or
account details on this cloned website, allowing the attacker to happily steal and utilize
the information for illicit reasons.

18. PRECAUTIONS

19. •Guard your financial and other
sensitive information
•Picture social networking sites as
billboards in cyberspace
•Be cautious about meeting your
new cyber friends in person
•Think twice before clicking on links
or downloading attachments in
emails.
•Protect your computer
