A form of criminal activity using social engineering techniques through email or instant messaging. Phishers attempt to fraudulently acquire other people's personal information, such as passwords and credit card details, by masquerading as a trustworthy person or business in an apparently official electronic communication. Typically, phishing emails request that recipients click on the link in the email to verify or update contact details or credit card information. Like spam, phishing emails are sent to a large number of email addresses, with the expectation that someone will act on the information in the email and disclose their personal information. Phishing can also happen via text messaging or phone.
