What is Phishing ??

Phishing (pronounced "fishing") is a type of online identity theft. It uses email and fraudulent websites that are designed to steal your personal data or information such as credit card numbers, passwords, account data, or other information.
Google defines phishing as an attack that takes place when someone masquerades as someone else to trick you into sharing personal or other sensitive information with them, usually through a fake website.

Phishing Technique


Phishing attack mainly takes place in two stages:


Stage 1: Spam Emails

Hackers send fake emails that resemble a valid message from a well-known or popular Web site or a company that the recipients might trust, such as a credit card company, bank, charity, or e-commerce online shopping site.The e-mail message could contain " threats or some gifts or lottery winner offers" that excites the consumer into action i.e clicking on the spoofed links provided in the e-mail.The email will contain spoofed links that look like legitimate e-commerce site links but which actually will connect to the hackers website.

Stage 2: Hackers website

The hacker will design a phishing (fake) website that has the same appearance as a legitimate e-commerce or banking website.
The purpose of fake website is to trick consumers into providing the following personal information:
  • Name and username.
  • Address and phone number.
  • Password or PIN.
  • Bank account number.
  • ATM/debit or credit card number.
  • Credit card validation code (CVC) or card verification value (CVV).
  • Social security number (SSN).


So how does a typical phishing e-mail look like ?


Here is an example of what a phishing scam may look like:


Hello!!

The scam email may contain some spelling mistakes (in orange) since cyber-criminals are not known for their spellings, atleast one link that looks legitimate (but is actually spoofed) and threats (in green) that threaten the users with account suspension or closure and email will be sent by the name of a popular company.

Remember a legitimate E-commerce website or Bank will not ask for your personal or account details unless you are opening account for the first time.

          4) Be Careful when Downloading Software

          Not downloading software from sites you don't trust even if they claim it is required; if a site says that a plugin is necessary, go directly to the plugin vendor's web site instead;
