本篇为 CS 4.4 二开基础篇，主要对整个破解流程、漏洞修复、主题修改、新增功能进行讲解，针对CS的扫描方法及Bypass方法后续进行补充。
一
使用工具
1.Idea 2023
2.java-decompiler.jar
3.cs 4.4
4.CrackSleeve
二
逆向流程
新建两个文件夹，cs_bin里面放原版cs，cs_src放之后反编译过后的cs，再将java-decompiler.jar放到根目录。目录结构如下：
cobaltstrike
├─cs_bin
│ └─ cobaltstrike.jar
└─cs_src
└─java-decompiler.jar
切换 java 版本到 java 11：
sudo update-alternatives --config java
在根目录输入以下命令将cs_bin/cobaltstrike.jar进行反编译，反编译后的文件放到cs_src文件夹中：
java -cp java-decompiler.jar org.jetbrains.java.decompiler.main.decompiler.ConsoleDecompiler -dgs=true cs_bin/cobaltstrike.jar cs_src/
正常反编译如图所示：
新建 idea java 项目，工程命名为cs，在工程下面新建两个文件夹：
把反编译好的cs_src/cobaltstrike.jar,复制到decompiled_src中，然后把它解压出来，可看到一个完整的反编译后的目录：
随后把原始的cs_bin/cobaltstrike.jar，复制到lib中：
接下来点击File->Project Structure->Modules，点击Dependencies，点击+号选择JARs or Directories：
选择lib中的原版 cobalt strike.jar，点击ok，勾选：
打开lib->META-INF->MANIFEST.MF，可以看到Main Class，复制aggressor.Aggressor：
至此依赖关系设置完了，现在进入File->Project Structure->Artifacts—>JAR—>From modules with dependencies：
Main Class填入aggressor.Aggressor，点击ok，再点击Apply：
接下来到decompiled_src/aggressor/Aggressor.java，右键选择Refactor->Copy File：
点击 To directory 右边的...：
新建目录，目录创建在src下，src目录是我们进行修改代码的地方：
创建aggressor，名字必须要与decompiled_src一致，如果是在aggressor下拷贝的文件就要放在src/aggressor下。如果是在aggressor/bridges下拷贝的文件就要放在src/aggressor/bridges下，目录结构必须保持一致：
完成上面的操作后Aggressor.java就被拷贝到src/aggressor，并且自动打开了Aggressor.java：
打开decompiled_src/META-INF/MANIFEST.MF，把里面的所有内容复制到src/META-INF/MANIFEST.MF：
修改前：
修改后：
之后就是我们要修改哪个文件，就可以在完整的源码中找到那个文件，然后右键Refactor然后Copy File到这个目录然后进行修改，修改完成之后就可以选Build—>Build Artifacts—>Build进行编译，编译后的文件在out -> artifacts -> cs_jar -> cs.jar：
点击Run->Profile->Edit Configurations设置参数，点击+号，选择JAR Application：
Name可以随便输入，我输入的是MyCs，在Path to JAR中选择out中我们修改并编译好的jar包，
设置VM options：-XX:+AggressiveHeap -XX:+UseParallelGC
选择好后点击Apply：
运行之后像下面这样就说明成功了，剩下的就是破解许可证和除掉插桩了：
三
永久许可
修改/src/common/Authorization.java文件：
先在src目录下新建common目录:
接着修改Authorization()函数，直接用下面的代码对该函数进行覆盖：
public Authorization() {
try {
this.watermark=999999;
this.validto="forever";
this.valid = true;
final byte[] bytes = {94, -104, 25, 74, 1, -58, -76, -113, -91, -126, -90, -87, -4, -69, -110, -42};
MudgeSanity.systemDetail("valid to", "perpetual");
MudgeSanity.systemDetail("id", this.watermark + "");
SleevedResource.Setup(bytes);
}
catch (Exception ex2) {
MudgeSanity.logException("auth file parsing", ex2, false);
}
}
虽然我们已经有了许可，但因为暗桩的存在我们无法正常运行。
四
去除暗桩
存在暗桩的地方：
common目录下的 Helper、Starter、Starter2 清除暗桩后可以进入客户端：
直接搜每个代码的exit，将其注释掉：
最后再重新build artifacts，再运行就可以了：
beacon/CommandBuilder中的暗桩会让client和temserver连续连接4小时后无法执行命令，将这部分注释掉：
至此除去暗桩部分就完成了。
五
漏洞修复
CS 修复错误路径泄漏stage
修改 cloudstrike/WebServer.java，新增对uri的判断，如果请求的uri开头不是/就相应404，新增代码如下：
else if (!uri.startsWith("/")) {
return this.processResponse(uri, method, header, param, false, null, new Response("404 Not Found.","text/html",""));
}
CVE-2022-39197 RCE
该漏洞是通过XSS造成的RCE，需要修改common/BeaconEntry.java将xss漏洞点进行修复：
下载commons-lang3-3.13.0.jar与commons-text-1.10.0.jar，导入到lib文件夹中：
接着设置Project Structure中的Modules和Artifacts：
接着在代码中使用StringEscapeUtils.escapeHtml4对漏洞点进行转义就完成了漏洞的修复。
import org.apache.commons.text.StringEscapeUtils;
HashMap var1 = new HashMap();
var1.put("external", StringEscapeUtils.escapeHtml4(this.ext));
var1.put("internal", StringEscapeUtils.escapeHtml4(this.intz));
var1.put("host", StringEscapeUtils.escapeHtml4(this.intz));
var1.put("user", StringEscapeUtils.escapeHtml4(this.user));
var1.put("computer", StringEscapeUtils.escapeHtml4(this.comp));
var1.put("last", StringEscapeUtils.escapeHtml4(this.diff + ""));
var1.put("lastf", StringEscapeUtils.escapeHtml4(this.getLastCheckin()));
var1.put("id", StringEscapeUtils.escapeHtml4(this.id));
var1.put("pid", StringEscapeUtils.escapeHtml4(this.getPid()));
var1.put("is64", StringEscapeUtils.escapeHtml4(this.is64));
var1.put("pbid", StringEscapeUtils.escapeHtml4(this.pbid));
var1.put("note", StringEscapeUtils.escapeHtml4(this.note));
var1.put("barch", StringEscapeUtils.escapeHtml4(this.barch));
var1.put("arch", StringEscapeUtils.escapeHtml4(this.barch));
var1.put("port", StringEscapeUtils.escapeHtml4(this.getPort()));
var1.put("charset", StringEscapeUtils.escapeHtml4(this.getCharset()));
var1.put("phint", StringEscapeUtils.escapeHtml4(this.hint + ""));
var1.put("process", StringEscapeUtils.escapeHtml4(this.proc));
var1.put("_accent", StringEscapeUtils.escapeHtml4(this.accent));
var1.put("listener", StringEscapeUtils.escapeHtml4(this.lname));
var1.put("build", (this.build));
var1.put("address", this.getIpAddress(this.ext)); // add address
六
主题修改
修改配置界面提示
aggressor/dialogs/ConnectDialog文件：
修改后：
启动服务端测试：
teamserver文件：
if [ -e ./cobaltstrike.store ]; then
echo "Will use existing X509 certificate and keystore (for SSL)"
else
echo "Generating X509 certificate and keystore (for SSL)"
keytool -keystore ./cobaltstrike.store -storepass 123456 -keypass 123456 -genkey -keyalg RSA -alias cobaltstrike -dname "C=US, ST=Maryland, L=Pasadena, O=Brent Baccala, OU=FreeSoft, CN=www.freesoft.org/[email protected]"
fi# start the team server.
java -XX:ParallelGCThreads=4 -Dcobaltstrike.server_port=22222 -Djavax.net.ssl.keyStore=./cobaltstrike.store -Djavax.net.ssl.keyStorePassword=231422 -server -XX:+AggressiveHeap -XX:+UseParallelGC -classpath ./csproject.jar server.TeamServer $*
teamserver <host> <password> [/path/to/c2.profile] [YYYY-MM-DD]

<password> is the shared password to connect to this server
[/path/to/c2.profile] is your Malleable C2 profile
[YYYY-MM-DD] is a kill date for Beacon payloads run from this server
启动客户端测试：
client文件：
java -XX:ParallelGCThreads=4 -XX:+AggressiveHeap -XX:+UseParallelGC -Xmx1024M -jar csproject.jar $*
修改客户端 About 和图标
原版：
1.介绍部分位置在resources/about.html。
2.许可部分位置在resources/credits.txt。
3.图标位置在resources/armitage-icon.gif和resources/armitage-logo.gif，icon是32×32px，logo是256×256px。
关于图标的引用在aggressor/dialogs/AboutDialog中，可以对引入的logo大小进行修改，我将大小改为了192×192px，并设置图片与许可之间相隔10px：
package aggressor.dialogs;
import aggressor.Aggressor;
import common.AObject;
import common.CommonUtils;
import dialog.DialogUtils;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Image;
import java.awt.Rectangle;
import javax.swing.BorderFactory;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.text.DefaultCaret;public class AboutDialog extends AObject {
public void show() {
JFrame var1 = DialogUtils.dialog("About", 320, 200);
var1.setLayout(new BorderLayout());Icon originalIcon = DialogUtils.getIcon("resources/armitage-logo.gif");
ImageIcon icon = (ImageIcon) originalIcon;
Image image = icon.getImage();
Image scaledImage = image.getScaledInstance(192, 192, Image.SCALE_SMOOTH);
icon = new ImageIcon(scaledImage);JLabel var2 = new JLabel(icon);
var2.setBackground(Color.black);
var2.setForeground(Color.gray);
var2.setOpaque(true);
var2.setIconTextGap(5); // Set the gap between the icon and text to 5pxJTextArea var3 = new JTextArea();
var3.setBackground(Color.black);
var3.setForeground(Color.gray);
var3.setEditable(false);
var3.setFocusable(false);
var3.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
var3.setOpaque(false);
var3.setLineWrap(true);
var3.setWrapStyleWord(true);String var4 = CommonUtils.bString(CommonUtils.readResource("resources/about.html"));
var2.setText(var4);
var3.scrollRectToVisible(new Rectangle(0, 0, 1, 1));
((DefaultCaret)var3.getCaret()).setUpdatePolicy(1);JScrollPane var5 = new JScrollPane(var3, 22, 31);
var5.setPreferredSize(new Dimension(var5.getWidth(), 100));String var6 = CommonUtils.bString(CommonUtils.readResource("resources/credits.txt"));
var3.setText(var6);var5.setBorder(BorderFactory.createEmptyBorder(0, 0, 0, 0));
var1.add(var2, "Center");
var1.add(var5, "South");
var1.pack();
var1.setLocationRelativeTo(Aggressor.getFrame());
var1.setVisible(true);
}
}
与原文件对比：
修改后：
修改界面主题
CS使用的是Swing UI，这里下载flatlaf主题：
https://mvnrepository.com/artifact/com.formdev/flatlaf/3.2
将下载后的jar文件导入到lib文件夹中：
打开Project Structure，打开Modules->Dependencies，添加这个jar到依赖中，勾选然后应用：
接着打开artifacts，引用flatlaf.jar，再点击应用：
添加后：
接着在主函数调用这里直接调用主题，文件为aggressor/Aggressor.java：
FlatLightLaf.setup();
要把主题的代码放在super.initializeStarter(this.getClass());前面，这行代码是进行初始化的。
因为已经导入了包，所以在输入Flat后就会提示可选主题，我使用的是明亮主题，运行后：
修复图标问题
session 修复
修复：
在aggressor/browsers/Sessions中添加：
导入包：
import java.awt.Component;
import java.util.function.Consumer;
import javax.swing.Icon;
import javax.swing.JLabel;
import javax.swing.JTable;
import javax.swing.table.TableCellRenderer;
import javax.swing.table.TableColumn;
新增修复代码并居中：
// repair session show
this.table.getColumnModel().getColumns().asIterator().forEachRemaining(new Consumer<TableColumn>() {
public void accept(TableColumn tableColumn) {
tableColumn.setCellRenderer(new TableCellRenderer() {
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
Component tableCellRendererComponent = table.getDefaultRenderer(String.class).getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
((JLabel) tableCellRendererComponent).setIcon(null);
((JLabel) tableCellRendererComponent).setHorizontalAlignment(JLabel.CENTER); // 设置水平居中对齐
return tableCellRendererComponent;
}
});
}
});

七
新增功能
session 新增 IP 归属地显示
查询IP使用的库为：https://github.com/jarod/qqwry-java
在src目录下新建qqwry目录，将源码拷贝进去：
aggressor/browsers/Sessions.java新增：
cs 4.5猫猫版将所有自定义函数封装到了util.Utils中，然后再调用。
把qqwry.dat放到resources中，引用路径则为resources/qqwry.dat：
public static String getIpAddress(String ipaddress) {
if (ipaddress.length() > 15 || ipaddress.equals("unknown") || ipaddress.equals("")) {
return "未知";
}
try {
// QQWry qqwry = new QQWry(Paths.get("qqwry.dat", new String[0]));byte[] data = CommonUtils.readResource("resources/qqwry.dat"); // add
QQWry qqwry = new QQWry(data);IPZone ipzone = qqwry.findIP(ipaddress);
return ipzone.getMainInfo();
} catch (Exception e) {
return "Exception: " + e.getMessage();
}
}
这样直接调用会很卡顿，因此使用static解决程序开销问题：
/* add address */
private static QQWry qqwry;
static {
try {
byte[] data = CommonUtils.readResource("resources/qqwry.dat");
qqwry = new QQWry(data);
} catch (Exception e) {}
}
public static String getIpAddress(String ipaddress) {
if (ipaddress.length() > 15 || ipaddress.equals("unknown") || ipaddress.equals("")) {
return "未知";
}
try {
// QQWry qqwry = new QQWry(Paths.get("qqwry.dat", new String[0]));IPZone ipzone = qqwry.findIP(ipaddress);
return ipzone.getMainInfo();
} catch (Exception e) {
return "Exception: " + e.getMessage();
}
}
然后在toMap()中再调用这个函数：
var1.put("address", this.getIpAddress(this.ext)); // add address
