TCP fingerprint

[support]

Recently several users have stated that BAS is being detected by fingerprint com site.

Report usually looks like this: "If proxy is set, proxy, site will mark you as using VPN, https://imgur.com/Kg1epHb"

The issue is caused by TCP fingerprinting and has nothing to do with BAS. Here are several tests to prove this:

1. Use fingerprint with tags "Linux,Chrome", Linux based proxy and you will get following result https://imgur.com/AHGvYWi

2. Use Windows based VPS, install socks proxy and run the test with it, result will be following https://imgur.com/jSyihGc

It is possible to spoof TCP fingerprint only on proxy level, so you should contact your proxy provider to fix issue.

Looks like those fags are reading this forum, and creating some new fucking antifraud solution based on FastSpace's posts. Or is it FastSpace by himself?)
p.s. Those fuckers even did not think too much about their logo, fkn thieves
p.p.s FastSpace and others, it's always better don't talk too much about some non-public things, just send it to developer's email in private if you want to fix anything.

Well, I believe that not many websites detect users by fingerprinting the TCP stack. I also think that websites have many other methods to identify and categorize user accounts.

Additionally, if a user is not using a TCP connection to a website, the website will not be able to detect it. However, many proxies only support TCP connections, which is why we might have a problem with proxies.

Hi, so can bas support tcp fingerprint/connection type leaks?

Short answer is "NO".
