While NetNTLM v2 presents an improvement over previous versions, its susceptibility to certain attack types and the emergence of superior alternatives like Kerberos suggest a gradual shift away from its use. For modern, high-security environments, exploring more robust and versatile authentication methods...
NTLMv2_RESPONSE结构很容易理解和解析,因为它只包含16字节的响应和可变大小的客户端质询。客户端的质询可以概括为使用从安全帐户管理器 (SAM) 或 Active Directory (AD) 获得的 NT 哈希构建的 LMv2 和 NTv2 哈希,并使用HMAC-MD5对用户和域名进行哈希。所有这些都形成了NetNTLMv2哈希,这是密码破解工具如 John ...
