Phishing uses an innocent-looking email to entice unwary recipients to click on a deceptive link, giving hackers access to their information or a network. In “spear-phishing,” the email is tailored to fool a specific person. From The New York Times report, 'The Perfect Weapon: How Russian Cyberpower Invaded the U.S.':
"A second team of Russian-affiliated hackers began to target the D.N.C. and other players in the political world, particularly Democrats. Billy Rinehart, a former D.N.C. regional field director who was then working for Mrs. Clinton’s campaign, got an odd email warning from Google.
“Someone just used your password to try to sign into your Google account,” the March 22 email said, adding that the sign-in attempt had occurred in Ukraine. “Google stopped this sign-in attempt. You should change your password immediately.”
Mr. Rinehart was in Hawaii at the time. He remembers checking his email at 4 a.m. for messages from East Coast associates. Without thinking much about the notification, he clicked on the “change password” button and half asleep, as best he can remember, he typed in a new password.
What he did not know until months later is that he had just given the Russian hackers access to his email account."
