NTLM挑战模式散列认证加密协议过程，算法实现与一些想法 转摘请注明作者和安全焦点 作者：FLASHSKY SITE：WWW.XFOCUS.NET，WWW.SHOPSKY.COM 邮件：flashsky@xfocus.org 作者单位：启明星辰积极防御实验室 说明： 本来先从看见小四的《LM/NTLM验证机制》就没准备发的，但是从如下几点考虑还是发： 1。给出完全的算法实现代码 2。小四的关于NTLM，LM的过程针对返回会话KEY的有效，针对完全挑战模式下说明并非完全 3。一些新的思路和思考 4。安全BLOB的结构说明 一：NTLM认证算法过程 1。客户端申请挑战 安全BLOB的结构如下： { CHAR DESC[8]=“NTLMSSP”； DWORD NO=1； //顺序号 DWORD FLAG； WORD DOMAINNAMELEN； //域名长度 WORD DOMAINNAMEMAXLEN；//域名最大长度 DWORD DOMAINNAMEOFFSET；//域名便移 WORD HOSTNAMELEN； //主机名长度 WORD HOSTNAMEMAXLEN； //主机名最大长度 DWORD HOSTNAMEOFFSET； //主机名便移 CHAR HOSTNAME[HOSTNAMELEN]；//主机名 CHAR DOMAINNAME[DOMAINNAMELEN]；//域名 } 2。服务器返回挑战，这个挑战是一个8字节的随机数 安全BLOB的结构如下： { CHAR DESC[8]=“NTLMSSP”； DWORD NO=2； //顺序号，必须为2 WORD DOMAINNAMELEN； //帐户域名长度 WORD DOMAINNAMEMAXLEN； //帐户域名最大长度 DWORD DOMAINNAMEOFFSET；////帐户域名偏移 DWORD FLAG； BYTE CHALLAGE[8]； //8字节挑战 BYTE RE[8]； //保留8字节，必须为0 WORD HOSTNAMELISTLEN； //主机名列表长度 WORD HOSTNAMELISTMAXLEN；//主机名列表最大长度 DWORD HOSTNAMELISTOFFSET；//主机名列表偏移 CHAR DOMAINNAME[DOMAINNAMELEN]； CHAR HOSTLISTNAME[HOSTNAMELISTLEN]； //这里是多个结构组成 //每个结构如下： //WORD ITEMNO；索引 //WORD HOSTNAMELEN；主机名长度 //BYTE HOSTNAME[HOSTNAMELEN]：主机名 } 3。客户端加密密码散列 其实这个过程还是很复杂的 如果是明文口令，先将此口令转化成散列，如果是系统用户则直接根据令牌从SESSION表中取出散列。 这下面就是小四的文章中没提到的过程 客户端先生成一个随机KEY，然后和服务器端的挑战使用MD5算法生成16字节的散列，但MS只取前8字节做为加密KEY，其实后面的散列加密并非是使用挑战直接加密的，而是 使用此加密KEY进行加密的。 这个算法的代码如下：romkey就是客户端生成的一个随机KEY，challage就是服务器挑战 void challagetorkey(unsigned char * romkey,unsigned char * challage,unsigned char * enkey) { unsigned char LM[0x58]; md5init(LM); *(DWORD *)LM=0x200; memcpy(LM+0X18,challage,8); memcpy(LM+0X20,romkey,8); *(DWORD *)(LM+0x28)=0x80; *(DWORD *)(LM+0x50)=0x80; md5final(LM); memcpy(enkey,LM+8,8); } 然后再使用生成的加密KEY加密MD4生成的NTLM散列，具体的过程在下四的文章中有详细介绍，这里就不再讲了，后面给出了完全实现的代码。 同时还会先选择一个RC4的KEY，对MD4生成的NTLM散列用MD4再生成一个散列，再用HMACMD5算法，加密KEY，这个散列计算出一个0X10字节的散 列，用此散列和rc4_key函数生成rc4的key表，最后用这个KEY表和先选择的RC4的KEY生成一个0X10字节的RC的结果出来。 但要注意的是：通常情况下，这个RC4的结果并没用于认证。 安全BLOB的结构如下： { CHAR DESC[8]=“NTLMSSP”； DWORD NO=3； //顺序号，必须为3 WORD RANDOMKEYLEN； //客户端随机KEY长度，固定为0X18 WORD RANDOMKEYMAXLEN； //客户端随机KEY最大长度，固定为0X18 //其实客户端随机KEY只有8字节，但是后面补0添满0X18字节 DWORD RANDOMKEYOFFSET；////客户端随机KEY偏移 WORD ENNTLMLEN； //加密的NTLM散列长度，固定为0X18 WORD ENNTLMMAXLEN； //加密的NTLM散列最大长度，固定为0X18 DWORD ENNTLMOFFSET； //加密的NTLM散列偏移 WORD HOSTNAMELEN； //主机名长度 WORD HOSTNAMEMAXLEN；//主机名最大长度 DWORD HOSTNAMEOFFSET；//主机名偏移 WORD USERNAMELEN； //用户名长度 WORD USERNAMEMAXLEN；//用户名最大长度 DWORD USERNAMEOFFSET；//用户名偏移 WORD USERDOMAINLEN； //帐户域名长度 WORD USERDOMAINMAXLEN；//帐户域名最大长度 DWORD USERDOMAINOFFSET；//帐户域名偏移 WORD ENNTLMRC4LEN； //加密的RC4 NTLM散列长度，固定为0X10 WORD ENNTLMRC4MAXLEN； //加密的RC4 NTLM散列最大长度，固定为0X10 DWORD ENNTLMRC4OFFSET； //加密的RC4 NTLM散列偏移 DWORD FLAG； CHAR HOSTNAME[HOSTNAMELEN]；//主机名 CHAR USERNAME[HOSTNAMELEN]；//用户名 CHAR USERDOMAINNAME[HOSTNAMELEN]；//帐户域名 RANDOMKEY[0X18]；//其实客户端随机KEY只有8字节，但是后面补0添满0X18字节 ENNTLM[0X18]； ENRC4NTLM[0X10]； } 4。服务器认证 服务器获得客户端随即KEY以后，也和挑战运算获得此加密KEY，然后计算加密的NTLM散列做对比进行判断。 5。一些思考 主要是关于重放攻击的，其实真正的加密KEY是挑战和客户端随机KEY做MD5运算的结果，那么如果我们嗅探出了一个挑战，随机KEY就 能计算出加密KEY，如果我们发起一个请求获得一个挑战2，如果能计算一个随即KEY2（这个可由我们自己控制），满足MD5（挑战2，随即KEY2） =加密KEY，那么我们就能发送我们修探获得的安全BLOB中的加密散列的内容来获得认证。 当然MD5的算法本事就是要防碰撞的，但是在MS的SMB实现中，由于MD5生成的是16字节的散列，但是用来做加密KEY的只是前8个字节，那 么对于寻找只满足部分（前8字节）碰撞的算法复杂度就会大大的降低，当然我们在MD5中唯一能控制的东西就是随即KEY，但是挑战KEY已知，其实 针对加密算发是常量（因为加密内容固定为0X1O字节，其他的内容可以常量），应该来说还是很有希望的。不过就我的数学水平而已，尝试了 一下就被难到了，希望对MD5碰撞有研究的人给予指教。下面就是给出的一个针对其挑战，随即KEY到加密KEY的替代函数： void challagetorkey(unsigned long c1,unsigned long c2,unsigned long r1,unsigned long r2) { //我们把挑战看做2个unsigned long的数C1,C2，客户端随即KEY也看做2个unsigned long的数R1,R2 //最后生成的是B1，D1，S1，D2，但其实用做加密KEY的只是B1，D1而已 //如果我们知道B1，D1，C1，C2，是否能找过一个R1，R2，使得满足这个函数呢？ //按照概率是针对每个B1，D1都有可能找到对应的R1，R2，因为MD5的算发要求是每个字节的变化都应该平均分布的 //我们可控的是256的8次方，结果也是256的8次方 //即使不是完全平均分布的，在测试100个挑战中总会有满足的吧？ //而算法复杂度对于16字节的256的16次方应该降低了不少 //那么再退一步说，如果我们知道B1，D1，C1，C2，R1，如果能解出R2也行，我们对R1实行穷举 //R1是256的4次方，4亿左右的穷举对现在的机器不应该是负担吧？当然真正实现工具由于认证要求，可能要求在10分钟以内 //但是如果我们在2天内能找到结果，也能说明很多问题 DWORD a1,d1,d2,s1;
