Some more bits of wisdom:
Phishing is the word commonly used where fraudsters try to fish for your online identity - your login ID, user name, account number, password, phone number, address, and any other details that will help them gain access to yout accounts. So, do not fall victim to these scams - Don't follow links, and learn how to check authenticity of emails and web sites.
Emails, and even web pages, are fairly easy to "forge". Moreover, they can be hijacked and the content altered by frausters. There are ways to check for tampering on a web site but usually very little to reveal that an email message has been compromised.
