# Brute force attacks Dictionary attacks and other kinds of brute force attacks often rely on the ability to send lots of requests per second in order to, for example, try different passwords to hack an account. In those cases, the faster our server responds, the easier is for the attacker to try many passwords per second. One way of making it difficult for the attackers is to add an intentional delay to the response, so the amount of time needed to try a reasonable amount of passwords rises quickly, hopefully discouraging the attacker. By setting the `isSensibleToBruteForceAttacks` setup key to true when creating the [Action](/reference/core-classes/action/methods.md#__construct-setup) object, Cherrycake will take care of adding this delay to the request. The delay is only added when the method called by the action returns `false`. Be sure to return `false` in methods mapped as actions when the sensible task was unsuccessful. For example: If a received password or key of any kind was checked against a database or any kind of authentication method, and it failed. > A random delay is used to emulate an unstable connection for added stealthiness. This can be adjusted by setting the `sleepSecondsWhenActionSensibleToBruteForceAttacksFails` configuration key of the [Actions](/reference/core-modules/actions-1.md) module. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://cherrycake.tin.cat/guide/actions-guide/brute-force-attacks.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
