Pronounced "fishing," it is a scam to steal valuable information such as credit card and social security numbers, user IDs and passwords. Also known as "brand spoofing," an official-looking email is sent to potential victims pretending to be from their bank or retail establishment. Emails can be sent to people on selected lists or any list, expecting some percentage of recipients will actually have an account with the organization.
Email Is the "Bait"
The email states that due to internal accounting errors or some other pretext, certain information must be updated to continue your service. A link in the message directs the user to a Web page that asks for financial information. The page looks genuine, because it is easy to fake a valid website. Any HTML page on the Web can be copied and modified to suit the phishing scheme. Rather than go to a Web page, another option is to ask the user to call an 800 number and speak with a live person, who makes the scam seem even more genuine.
Anyone Can Phish
A "phishing kit" is a set of software tools from phishing developers that help the novice phisher copy a target website and make mass mailings. It may even include lists of email addresses (how thoughtful of people to create these kits!). In the meantime, if you suspect a phishing scheme, you can report it to the Anti-Phishing Working Group at www.antiphishing.org. See pharming
"Spear" Phishing and Longlining
Spear phishing is more targeted and personal. The message supposedly comes from someone in the organization everyone knows, such as the head of human resources. It could also come from someone not known by name, but with an authoritative title such as LAN administrator. If even one employee falls for the scheme and divulges sensitive information, it can be used to gain access to more of the company's resources.
The "longline" variant of spear phishing sends thousands of messages to the same person, expecting that the individual will eventually click a link. The longlining term comes from using a large number of hooks and bait on a long fishing line, and mobile phones are major targets for this approach.
