Targeted threats are singled out because of their focus: they are usually directed at a specific organization or industry. These threats are also designed to extract sensitive information from the target, so cyber criminals take a long time to prepare these threats. They are carefully documented, so the chances for successful compromise can be as big as possible. Targeted threats are delivered via email (phishing, vishing, etc.), they employ Zero Days and other vulnerabilities to penetrate an information system, and many more. Government and financial organizations are the most frequent targets for this type of cyber threat.
