Fraudulent emails and spoofing, formerly known as phishing.
What is a fraudulent email? (spoofing)
A fraudulent (spoof) email pretends to be from a well-known company, such as PayPal or eBay, in an attempt to get personal information from you. People who send spoof emails hope to use your information - such as credit and debit card numbers or account passwords - to commit identity theft.
