☭ A Call To Action

Comrades, who among you can say to have enjoyed the use of 5socks.net? Although the quality of material is high, the website never left the 1990s if we're being honest. As there is no API for users to manage proxies with, I became very frustrated and spent a couple of hours writing this utility.

During this time I noticed 5socks.net appears to have embedded code to detect other more, ah, unsophisticated automation tools at work (webdriver-based tools, to be frank, sorry). I will leave the analysis of the offending code fragment as a homework assignment in the bottom of the README.md.

🚀Install & Configuration

How to use the tool? It is very simple. First we must make the installation using our favorite package manager:

npm i -g 5socks
yarn global add 5socks

Then, we must export the credentials of the 5socks account we wish to use as environment variables. However, be careful, comrades! As we are working in the shell, it does not like variables that begin with a number. It shares this quality with our friend javascript. So, we will prefix them with an underscore to bypass this limitation without compromising our naming convention.

export _5SOCKS_USER='wombat'
export _5SOCKS_PASSWORD='lenin'
export DEBUG='5socks' # this is optional, but may be needed to troubleshoot issues

Now we are ready to begin work. The binary takes two positional parameters:

• Country: This is a two-character ISO Alpha-2 code. Examples: ['US', 'RU', 'SY']

• State/Region: Optional parameter, again a two-character ISO region code. Examples: ['CA', 'NY', 'FL']

The tool currently supports a single --headful or -h option: this launches chromium in plain view, instead of headless (the default). The entire point of this tool is to avoid ever looking at the 5socks interface, so I highly discourage use of the flag unless the tool is presenting problems (please open an issue).

Prerequisites

To ensure playwright has what it needs to launch chromium and perform the automated flow, please run the following in a shell:

npx playwright install-deps chrome

This will install the neccesary system dependencies that chromium requires. Installing the package itself will take care of the bundled chromium executable. Additionally, make sure that your node is >= 16, at least for this project. I personally recommend https://github.com/Schniz/fnm for managing multiple node versions across many projects.

If you choose to use it, note that the presence of the .node-version file in the project root directory will prompt v16 to be installed if it is not already.

🎈 Usage

Here are some example invocations of the binary:

5socks ru # Fetch a SOCKS5 proxy within the Russian Federation
5socks us ca # Fetch a SOCKS5 proxy in California, USA
5socks us -h # Fetch a USA proxy, launching browser in headful mode for debugging

A detailed ip lookup fingerprint will be presented once the proxy has been acquired:

{
  "ip": "82.147.116.195",
  "country": "RU",
  "asn": {
    "asnum": 12772,

    "user-agent": "got (https://github.com/sindresorhus/got)",
    "accept": "application/json",
    "accept-encoding": "gzip, deflate, br"
  }
}

The proxy will also be copied to the clipboard, allowing you to go straight ahead seamlessly with your work.

Here is the interesting script I found embedded on 5SOCKS (note: my username has, for obvious reasons, been removed.)

rBD = function () {
    var e = ["__webdriver_evaluate", "__selenium_evaluate", "__webdriver_script_function", "__webdriver_script_func", "__webdriver_script_fn", "__fxdriver_evaluate", "__driver_unwrapped", "__webdriver_unwrapped", "__driver_evaluate", "__selenium_unwrapped", "__fxdriver_unwrapped"],
        n = ["_phantom", "__nightmare", "_selenium", "callPhantom", "callSelenium", "_Selenium_IDE_Recorder"];
    for (windowDetectionKey in n)
        if (windowDetectionKeyValue = n[windowDetectionKey], window[windowDetectionKeyValue]) return !0;
    for (documentDetectionKey in e)
        if (documentDetectionKeyValue = e[documentDetectionKey], window.document[documentDetectionKeyValue]) return !0;
    for (documentKey in window.document)
        if (documentKey.match(/$[a-z]dc_/) && window.document[documentKey].cache_) return !0;
    try {
        if (window.external && window.external.toString() && -1 != window.external.toString().indexOf("Sequentum")) return !0
    } catch (e) {}
    return !!window.document.documentElement.getAttribute("selenium") || (!!window.document.documentElement.getAttribute("webdriver") || (!!window.document.documentElement.getAttribute("driver") || (1 == navigator.webdriver || !(!window.callPhantom && !window._phantom))))
};
if (rBD() == true) {
    try {
        hr = encodeURIComponent(window.document.location.href);
        an = encodeURIComponent(navigator.appName);
        av = encodeURIComponent(navigator.appVersion);
        res = window.screen.width + 'x' + window.screen.height;
        ua = encodeURIComponent(navigator.userAgent);
    } catch (e) {
        hr = 'error';
    };
