# Binary Pattern Binary Patterns are a sort of Regex search pattern for binary values. The following characters are allowed: * 0 - 9 / A - F: Fixed values that the current nibble needs to have * ?: Wildcard value to match any value As an example, let's take the Binary Pattern `AB ?? 5F ?A`. Searching for this pattern would look for any sequence of 4 bytes where the first byte has the value `0xAB`, the third byte the value `0x5F` and the fourth byte any value that has the lower nibble set to `0xA`. The second byte in the sequence can have any value as both nibbles are wildcarded. --- # 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.
