| Summary |
An adversary engages in pretexting behavior to solicit information from target persons, or manipulate the target into performing some action that serves the adversary's interests. During a pretexting attack, the adversary creates an invented scenario, assuming an identity or role to persuade a targeted victim to release information or perform some action. It is more than just creating a lie; in some cases it can be creating a whole new identity and then using that identity to manipulate the receipt of information. Pretexting can also be used to impersonate people in certain jobs and roles that they never themselves have done. In simple form, these attacks can be leveraged to learn information about a target. More complicated iterations may seek to solicit a target to perform some action that assists the adversary in exploiting organizational weaknesses or obtaining access to secure facilities or systems. Pretexting is not a one-size fits all solution. Good information gathering techniques can make or break a good pretext. A solid pretext is an essential part of building trust. If an adversary’s alias, story, or identity has holes or lacks credibility or even the perception of credibility the target will most likely catch on. |
| Prerequisites |
The adversary must have the means and knowledge of how to communicate with the target in some manner.The adversary must have knowledge of the pretext that would influence the actions of the specific target. |
| Solutions | An organization should provide regular, robust cybersecurity training to its employees to prevent successful social engineering attacks. |

Description
|
| CAPEC-163 |
An adversary targets a specific user or group with a Phishing (CAPEC-98) attack tailored to a category of users in order to have maximum relevance and deceptive capability. Spear Phishing is an enhanced version of the Phishing attack targeted to a specific user or group. The quality of the targeted email is usually enhanced by appearing to come from a known or trusted entity. If the email account of some trusted entity has been compromised the message may be digitally signed. The message will contain information specific to the targeted users that will enhance the probability that they will follow the URL to the compromised site. For example, the message may indicate knowledge of the targets employment, residence, interests, or other information that suggests familiarity. As soon as the user follows the instructions in the message, the attack proceeds as a standard Phishing attack. |
| CAPEC-410 |
An adversary engages an individual using any combination of social engineering methods for the purpose of extracting information. Accurate contextual and environmental queues, such as knowing important information about the target company or individual can greatly increase the success of the attack and the quality of information gathered. Authentic mimicry combined with detailed knowledge increases the success of elicitation attacks. |
| CAPEC-416 |
An adversary exploits inherent human psychological predisposition to influence a targeted individual or group to solicit information or manipulate the target into performing an action that serves the adversary's interests. Many interpersonal social engineering techniques do not involve outright deception, although they can; many are subtle ways of manipulating a target to remove barriers, make the target feel comfortable, and produce an exchange in which the target is either more likely to share information directly, or let key information slip out unintentionally. A skilled adversary uses these techniques when appropriate to produce the desired outcome. Manipulation techniques vary from the overt, such as pretending to be a supervisor to a help desk, to the subtle, such as making the target feel comfortable with the adversary's speech and thought patterns. |
