Possible Browser IP Leak? [SOLVED]



  • Hello everyone,

    Came across this issue recently. When setting the proxy it looks like it's leaking my real IP?
    I have tried multiple proxy services and have checked many, many.. many leak sites and bot detection. They all come back clean? But intresting enough - when looking at the network calls you'll notice under General Headers being sent 'Remote Address: XXX.XX.XXX:XXXX'. Maybe it's set to bypass the proxy on the bablosoft.com domain? I don't think so - Why? I've been building bots for hundreds of websites since day one of BAS. HTTP Requests with the client works 100% with 0 problems, but my browser based bots that are up against some popular sites have been recently getting blocked with 403 (Access Denied), Drops, Unsuccessful returns. When connecting to the sites with a normal browser hidden behind the same proxy that's 'blocked' everything works perfect - same with the HTTP client. After countless A/B/C testing - BAS <--> Manual (FireFox, Opera, Brave, Edge, even IE) <--> HTTP Client the end result is the connection. Even monitoring the traffic from BAS and multiple browsers.

    I've changed the browsers setting, proxy settings, even using Fingerprints to see if that would help. I've gone even as far as reinstalling BAS. (Saddly I do not have any version before 21.5.2 which is happening on this version also)

    Thoughts, Opinions, Solutions, or am I just crazy - ha?

    • Windows 10 Pro

    The following 2 images is testing via BAS browser & FireFox. HTTP Client returns the proxies IP.

    Last image is setting BAS to no proxy and setting the whole system to the proxy/VPN

    UPDATE: I found BAS version 21.4.2 on a USB and indeed, Looks like the proxy is being set correctly in 21.4.2 version.

  • Why has such an important subject not yet received an answer? Interestingly, waiting for a return of premium email support I am browsing the forum for more information and I came across your topic created 8 days ago!

    The same problem happens to me in the updated version (21.7.1)

    The information is divergent, somehow the site (ipleak.net) displays the proxy connection information correctly.

    But in the detection address link (https://fingerprints.bablosoft.com/headersorder) my real IP is detected! and this is something very problematic, I'm running my projects and testing from my personal computer, but believing that the proxy is being used efficiently, and now I come across this divergence of data makes me very worried!

    After all, why the website (https://fingerprints.bablosoft.com/headersorder) is able to detect my REAL IP and the other website does not?

    An issue that needs to be answered by administrators.

    The user asked a question in the premium support and duplicated it on the forum. In premium support, I answered him. Disable the setting "Use process tunneling to enable proxy".

  • @fox So, is there a bug in the "Use process tunneling to enable proxy" option? because I've always used BAS with this option enabled. And now I'm very worried about my anonymity with my projects.

    With the tunnel option disabled, the WebRTC configuration is also lost ... what else should I worry about not using the proxy as "Use process tunneling to enable proxy"?

    All requests to fingerprints.bablosoft.com go without a proxy, it is necessary for FingerprintDetector to work correctly (otherwise authorization would be disabled every time when using the Proxy action). Any other sites are not affected.

  • Yes I was told about the Process Tunneling to be turned off. I thought the domain was being bypassed by the proxy for a reason, glad it was confirmed. Lets all classify this as a Proxy Scare from my end!

    Thanks @Fox!



  • thankyou @Fox
