Ask HN: Does anyone know of a tool to see what data is sent to 3rd parties

9 points by oseibonsu 6y ago

I remember a tool from years ago that would analyze what data a website was sending to 3rd parties. Does anyone remember what it was called or know of something similar.

Disconnect browser extension had a graph which domains are requested, is it that you remember? https://commons.wikimedia.org/wiki/File:Screengrab_of_%27Disconnect%27,_(an_internet-browser_addon),_visualizing_the_many_trackers_on_the_website_%27abovetopsecret%27_(on_141127)-cropped.png https://commons.wikimedia.org/wiki/File:Screengrab_of_%27Dis...

The manual option is using ghostery and clicking in to each pixel URL to look at the paramaters. Many times the data is not obfuscated (in a facebook pixel you can see things like val=Ford, when you're browsing a page for a Ford truck)

There are lots of ways to do that. You can look at the developer tools provided by your browser. You can also run your browser through an intercepting proxy like burp or zap. The latter gives you the ability to intercept and step over actions, so you can really slow things down. I'd recommend using on of them.

You can use https://www.wireshark.org https://www.wireshark.org to see HTTP traffic and MITM yourself for HTTPS(https://unit42.paloaltonetworks.com/wireshark-tutorial-decrypting-https-traffic/ https://unit42.paloaltonetworks.com/wireshark-tutorial-decry...). That will only work for the data that you send to them yourself. You can't possibly see any data that they send to third parties that they send through their servers.

Divine Ease CBD Oil When we are talking about health, it is not just about a healthy body but also about sound mental health. Good health can be described as the condition where both our body as well as our mind are functioning properly. The main causes behind poor health conditions are diseases, improper diet, injury, mental stress, lack of hygiene, unhealthy lifestyle, etc. Over the past few years, our lifestyle has changed and we often tend to ignore the importance of healthy living in one way or the other. http://supplementstore4u.com/divine-ease-cbd-oil/ http://supplementstore4u.com/divine-ease-cbd-oil/ https://www.justgiving.com/crowdfunding/divineease-cbdoil https://www.justgiving.com/crowdfunding/divineease-cbdoil https://www.completefoods.co/diy/recipes/does-divine-ease-cbd-oil-have-side-effects https://www.completefoods.co/diy/recipes/does-divine-ease-cb... https://twitter.com/OilDivine/status/1331112869421780993 https://twitter.com/OilDivine/status/1331112869421780993 https://sites.google.com/site/glucafixbuy/divine-ease-cbd-oil https://sites.google.com/site/glucafixbuy/divine-ease-cbd-oi... http://supplementstore4u.com/ http://supplementstore4u.com/
