YARA Signatures

MalwareBazaar uses YARA rules from several public and non-public repositories, such as YARAhub and Malpedia.

Rule name:	skip20_sqllang_hook Create hunting rule
Author:	Mathieu Tartare <mathieu.tartare@eset.com>
Description:	YARA rule to detect if a sqllang.dll version is targeted by skip-2.0. Each byte pattern corresponds to a function hooked by skip-2.0. If $1_0 or $1_1 match, it is probably targeted as it corresponds to the hook responsible for bypassing the authentication.
