Phishing is a type of identity theft which uses fraudulent websites and/or ones email to steal personal information such as credit card numbers and/or account information.
Hackers may send emails linked to fraudulent websites asking one to provide personal information. Once they have done so, they will use that person's information to steal money from their account or obtain documents using that person's identity.
In most phishing instances, the hacker states a very important reason why the user must provide their personal information.
Please be careful when sharing personal information over the web.
