一、准备工作
目标软件是一个加了VMP并开启虚拟化及代码变异，脱壳过程略，直接看脱壳的结果

可以看到关键地方全部被虚拟化了，关于虚拟化处理起来我还没有很好的解决方案
二、去除反调试
timer1里有进程检测反调试，每2秒检测是否包含{“dnSpy”，“de4dot”，“64”，“32”，“ExtremeDumper”}字样，将timer1时钟设置为flase即可关闭检测

de4dot直接修改会清除vmp区段，这里我直接跳转到16禁止去c32修改的，将0xC98F6这里修改为0就可以啦

三、追码
解决反调试后我找了个软件来帮助解决虚拟化代码的问题，下面贴软件生成的log

四、分析算法
借助于软件的log分析起来应该不难，直接贴注册机成品算法了
首先是机器码的算法
[C#] 纯文本查看 复制代码
                public string doIt()                {                                                string text = null;                        foreach (ManagementBaseObject managementBaseObject in new ManagementClass("Win32_NetworkAdapterConfiguration").GetInstances())                        {                                ManagementObject managementObject = (ManagementObject)managementBaseObject;                                if (Convert.ToBoolean(managementObject["IPEnabled"]))                                {                                        text = managementObject["MacAddress"].ToString();                                        text = text.Replace(':', '-');                                }                                managementObject.Dispose();                        }                        return text;                }                public string run(string str)                {                        return BitConverter.ToString(new MD5CryptoServiceProvider().ComputeHash(Encoding.UTF8.GetBytes(str))).Replace("-", "");                }                                private void Form1_Load(object sender, EventArgs e)        {                        textBox1.Text = run(doIt().Replace("-", ""));                }

下面是注册机的算法
[C#] 纯文本查看 复制代码
   private void button1_Click(object sender, EventArgs e)        {                        string text;                        text = textBox1.Text.Replace("0","D");                        text = text.Replace("8", "C");                        text = text.Replace("7", "N");                        text = text.Replace("5", "Q");                        text = text.Replace("6", "R");                        text = text.Replace("L", "4");                        text = text.Replace("A", "2");                        text = text.Replace("B", "3");                        text = text.Replace("E", "0");                        text = text.Replace("F", "1");                        text = text.Replace("M", "9");                        textBox2.Text = ReverseA(text);        }                public string ReverseA(string text)                {                        char[] cArray = text.ToCharArray();                        string reverse = String.Empty;                        for (int i = cArray.Length - 1; i > -1; i--)                        {                                reverse += cArray[i];                        }                        return reverse;                }

一口气升级7个大模型SaaS应用，百度智能云：突出一个“开箱即用” - 2024/12/24

这一波大模型产业落地浪潮里，不少企业其实处在 “干瞪眼“的状态。

一种情况是，很多大模型产品看得见却摸不着，在台上一个个遥遥领先——今天Sora技精四座，明天英伟达的机器人又赢得满堂彩，可是到了台下一问：啥时候能用上啊？答曰：遥遥无期。

另一种情况是，企业想用上大模型，却又难免瞻前顾后——既要考虑场景融合，又得兼顾安全性，还要考虑打通现有系统，再加上各种部署成本和繁琐的采购流程……最后只能拂袖：罢了，再等等吧。

稳了！魔兽国服回归的3条重磅消息！官宣时间再确认！

昨天有一位朋友在大神群里分享，自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址，com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后，确实是网易的网址，也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情，因为以前都没有出现这样的情况，现在突然提示跳转到国服战网的网址，是不是说明了简体中文客户端已经开始进行更新了呢？
