In one sentence: Spear phishing is phishing aimed at one person or a small group, using details about them to look believable.
Why it matters: Attackers use information from sources such as websites and social media to make messages more convincing. These messages are harder to spot than mass phishing. If a message asks for money or a login, check with the sender in a second way, such as a phone call.
One thing to do: Look at one social media profile and remove details that you do not need to share, such as your workplace or phone number.
