Proxychains.exe is a proxifier for Win32(Windows) or Cygwin/Msys2 programs. It hijacks most of the Win32 or Cygwin programs' TCP connection, making them through one or more SOCKS5 proxy(ies).
Proxychains.exe hooks network-related Ws2_32.dll Winsock functions in dynamically linked programs via injecting a DLL and redirects the connections through SOCKS5 proxy(ies).
Proxychains.exe is a port or rewrite of proxychains4 or proxychains-ng to Win32 and Cygwin. It also uses uthash for some data structures and minhook for API hooking.
Proxychains.exe is tested on Windows 10 x64 1909 (18363.418), Windows 7 x64 SP1, Windows XP x86 SP3 and Cygwin 64-bit 3.1.2. Target OS should have Visual C++ Redistributable for Visual Studio 2015 installed.
WARNING: ANONYMITY IS NOT GUARANTEED!
WARNING: this program works only on dynamically linked programs. Also both proxychains.exe and the program to call must be the same platform and architecture (use proxychains_x86.exe to call x86 program, proxychains_x64.exe to call x64 program; use Cygwin builds to call Cygwin program).
WARNING: this program is based on hacks and is at its early development stage. Any unexpected situation may happen during usage. The called program may crash, not work, produce unwanted results etc. Be careful when working with this tool.
WARNING: this program can be used to circumvent censorship. doing so can be VERY DANGEROUS in certain countries. ALWAYS MAKE SURE THAT PROXYCHAINS.EXE WORKS AS EXPECTED BEFORE USING IT FOR ANYTHING SERIOUS. This involves both the program and the proxy that you're going to use. For example, you can connect to some "what is my ip" service like ifconfig.me to make sure that it's not using your real ip.
ONLY USE PROXYCHAINS.EXE IF YOU KNOW WHAT YOU'RE DOING. THE AUTHORS AND MAINTAINERS OF PROXYCHAINS DO NOT TAKE ANY RESPONSIBILITY FOR ANY ABUSE OR MISUSE OF THIS SOFTWARE AND THE RESULTING CONSEQUENCES.
Download the pre-built binaries from Release Page.
If you want to buid proxychains.exe yourself...
First you need to clone this repository and run git submodule update --init --recursive in it to retrieve all submodules.
Open proxychains.exe.sln with a recent version Visual Studio (tested with Visual Studio 2019) with platform toolset v141_xp on a 64-bit Windows.
Select the configuration (Debug/Release) and the platform (x86/x64).
Build the whole solution and you will see DLL file and executable file
generated under win32_output/.
Install Cygwin/Msys2 and various build tool packages (gcc,
w32api-headers, w32api-runtime etc). Run bash, switch to cygwin_build
/ msys_build directory and run make.
Copy proxychains*.exe, [cyg/msys-]proxychains_hook*.dll to some
directory included in your PATH environment variable. You can rename
the main executable (like proxychains_win32_x64.exe) to names you
favor, like proxychains.exe.
Last you need to create the needed configuration file in correct place. See "Configuration".
Proxychains.exe looks for configuration in the following order:
- file listed in environment variable
PROXYCHAINS_CONF_FILEor provided as a-fargument %USERPROFILE%\.proxychains\proxychains.conf(CSIDL_APPDATA)\Proxychains\proxychains.conf(On modern Windows versions, a typical path isC:\Users\<user name>\AppData\Roaming\ Proxychains\proxychains.conf)(CSIDL_COMMON_APPDATA)\Proxychains\proxychains.conf(On modern Windows versions, a typical path isC:\ProgramData\Proxychains\ proxychains.conf)
- file listed in environment variable
PROXYCHAINS_CONF_FILEor provided as a-fargument $HOME/.proxychains/proxychains.conf(SYSCONFDIR)/proxychains.conf/etc/proxychains.conf
For options, see proxychains.conf.
proxychains ssh some-server
proxychains "Some Path\firefox.exe"
proxychains /bin/curl https://ifconfig.me
Run proxychains -h for more command line argument options.
- Main program hooks
CreateProcessWWin32 API call. - Main program creates child process which is intended to be called.
- After creating process, hooked
CreateProcessWinjects the Hook DLL into child process. When child process gets injected, it hooks the Win32 API call below:CreateProcessW, so that every descendant process gets hooked;connect,WSAConnectandConnectEx, so that TCP connections get hijacked;GetAddrInfoWseries, so that Fake IP is used to trace hostnames you visited, allowing remote DNS resolving;- etc.
- Main program does not exit, but serves as a named pipe server. Child process communicates with the main program to exchange data including logs, hostnames, etc. Main program does most of the bookkeeping of Fake IP and presence of descendant processes.
- When all descendant processes exit, main program exits.
- Main program terminates all descendant processes when it receives a SIGINT (Ctrl-C).
Cygwin is fully supported since 0.6.0!
Switching the DLL injection technique from CreateRemoteThread() to
modifying the target process' entry point, proxychains.exe now supports
proxifying Cygwin/Msys2 process perfectly. (Even when you call them
with Win32 version of proxychains.exe). See DevNotes.
If you want to proxify MinGit busybox variant,
replace its busybox.exe with
this version modified by me.
See DevNotes.
ConEmu
prevents
its descendant processes to do SetThreadContext(). This means
proxychains.exe is in no way compatible with terminals based on ConEmu
(like cmder).
In the following period, I will try to re-structure proxychains.exe (files, functions, ...) and complete some to-dos at the same time.
- Domain name resolution should be case-insensitive
- Proxify osu!lazer launcher? (#11)
- Configuration file path (#9)
- Recognize IPv4-mapped fake IPv6 address
- Resolve proxy server name by custom hosts file, or at least declare it as not supported in docs
- Properly handle "fork-and-exit" child process ? (In this case the descendant processes' dns queries would never succeed)
- Remote DNS resolving based on UDP associate
- Hook
sendto(), coping with applications which do TCP fast open - Powershell wget bug
- IPs resolved from hosts file should also be filtered like fake ip (fixed in 0.6.8)
- Resolve encoding issue regarding Cygwin and Mintty (fixed in 0.6.7)
- Fake IPs should be filtered according to types of resolved IPs
and hints in
GetAddrInfoWandgethostbyname, otherwise crash may happen (fixed in 0.6.7) - Add an option to totally prevent "DNS leak" ? (Do name lookup on SOCKS5 server only) (fixed in 0.6.6)
- Connection closure should be correctly handled in
Ws2_32_LoopRecvandWs2_32_LoopSend(fixed in 0.6.5) - A large part of socks5 server name possibly lost when parsing configuration (fixed in 0.6.5)
- Correctly handle conf and hosts that start with BOM (fixed in 0.6.5)
- Detect .NET CLR programs that is AnyCPU&prefers 32-bit/targeted x86
/targeted x64. (These are "shimatta" programs, which must be
injected by
CreateRemoteThread()) (fixed in 0.6.2) -
ResumeThread()in case of error during injection (fixed in 0.6.1) - Fix choco
err_unmatched_machine(fixed in 0.6.1) - Get rid of Offending&Matching host key confirmation when proxifying git/SSH, probably using a FQDN hash function (fixed in 0.6.0)
- Tell the user if command line is bad under Cygwin (fixed in 0.6.4)
- Inherit exit code of direct child (fixed in 0.6.4)
Different file types are required to have different line endings, encodings.
