TrickBot Trojan Detection

This YARA rule detects the TrickBot trojan by identifying specific byte sequences ($entry_setup, $decrypt_function_snippet, $decrypt_function_snippet_wrapper) commonly found in its executable code. The rule requires the presence of the standard Windows PE magic number (0x5A4D) at the beginning of the file, along with the $entry_setup pattern, and at least one of the decryption function snippets.
