A technique used by hackers to obtain sensitive information. For example, using hand-crafted email messages designed to trick people into divulging personal or confidential data such as passwords and bank account information. This is an attempt to fraudulently obtain sensitive information from victims using email or other forms of messaging. Spear phishing is a sophisticated form of fraud that targets specific people and is preceded by research and reconnaissance to convince the victim that it’s a legitimate source. The best way to prevent successful phishing attempts is to require external verification when exchanging sensitive information such as passwords and keys.
