# Attack Possibility

Alongside its [severity](/docs/t/assessment/references/severity.md), each vulnerability in a Takumi assessment report is assigned an attack possibility, which is classified into the following 4 levels.

| Possibility | Description                                                                                                                                                                                 |
| ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| High        | Exploitable at any time, with no special precondition.                                                                                                                                      |
| Medium      | Exploitable once a certain condition is met, such as luring a victim into an action or an unusual configuration being in place.                                                             |
| Low         | Requires relatively complex conditions, or several conditions to hold at the same time.                                                                                                     |
| Impossible  | Cannot be carried out at the time of the assessment, or requires conditions an ordinary attacker cannot meet, such as already holding administrator privileges or the target's credentials. |
