Phishing is fraud involving someone pretending to represent a legitimate company or agency to gain your trust. . Scammers frequently pose as government officials, computer technicians, bank employees, or company executives. Phishing is the starting point for many kinds of fraud, like financial identity theft, password theft, and account theft.
A few of the most common categories for phishing scams last year included:

Phishing attacks often begin with email or text messages. Signs that an email or text is fraudulent include poor grammar, misspellings, and poor language use or unfamiliar phrases. Some messages may enclose telephone numbers in odd sets of parenthesis or spell out certain parts of an email in an attempt to get by spam filters.
The “From” box can say anything. The sender’s email address, however, cannot easily be spoofed. Banks and the government do not use Gmail or other third-party email services. Double-check the sender’s actual address for validity and to match with the sender’s purported identity.
Phishing messages often contain links. The links may look legitimate but you should never click on one. Phishing links lead to dangerous websites designed to steal your information or download malware to your computer.
If a message directs you to click a link to go to your bank’s website (or any other website), and you have any reason to be suspicious, don’t click the link. Instead, open a browser and go to your bank (or other) website by typing in the address yourself.
Links can be deceptive.
