There has been a lot of talk in the media lately about web surveillance, from everyone, from the government to your provider. The less they talk about it, the less they talk about surveillance at the local level.
In this article we will see if everyone can see the sites you visit thanks to their WiFi.
Can anyone see the websites I visit via their Wifi?
If you are using someone else’s WiFi, if he or she is very dedicated, he or she may be looking at the websites you visit. But before you worry too much, you have to understand that this is a lot of work and perhaps beyond the capabilities of most people.
The easiest way would be to use a computer to which a person who owns the network has access. If this were the case, a simple check of your browsing history would show that you are browsing (assuming you haven’t deleted your browsing history).
If you’re on your own stand-alone device, you’ll need to set up monitoring software (e.g. sniff packages – such as Wireshark… we’ll come back to that later) that intercepts all traffic between the device and the router (or behind the router), or a log file on the router.
However, it should be noted that this is not an easy task for them, so it is very unlikely that if you have a friend or family member, wifi will be used.
If you’re on an unsecured network, or if you’re using the wireless network of a person or place you don’t trust, that person or place may naturally be motivated to view the Web sites you visit. Unsecured WiFi can be checked or sniffed with open source software quite easily.
In addition, a hacker on an unsecured network, or simply someone who has created a network for malicious purposes, can use listening programs to access valuable data such as passwords or credit card information.
It should be noted that many websites currently use HTTPS, which encrypts all the information exchanged between your computer and the website you are using, making it much more difficult for a spy to obtain your personal and private information.
Directly: If it’s possible to keep track of the sites you’ve visited while visiting them using someone else’s WiFi, it’s a daunting task. If you think that the person does not have the reasons and/or the know-how, it is unlikely that he or she will be able to see the websites you visit.
It is always possible to monitor traffic, especially if you are monitoring the network. The risks are generally low, but for public wireless networks and/or networks with unsecured wireless networks the risks are… The risks are increasing.
We recommend using a paid VPN if possible if you are not sure which network you are using. Try waiting until you get home when you need to make a payment or use any type of online banking.
How do you want to look at someone with my Wi-Fi?
As we just said, it’s not easy to check the websites someone is surfing. It is also morally highly questionable, especially if the person does not know that you are checking his or her browser, and even potentially illegal if you are looking for confidential information such as bank details.
If you just want to make sure that people surfing on your network don’t go to inappropriate websites, it’s probably best to implement strong parental controls on your network.
Parental controls can do anything from blocking certain types of content and IP addresses to blocking all access to the Internet, with the exception of certain websites. Even if you can’t see who’s surfing, it’s certainly an easier way to limit surfing on your network.
To see what people were watching with your Wi-Fi, some routers keep a log of the IP addresses they visited.
If so, you should be able to connect to your router to find a list of IP addresses. Once you’ve done that, of course, you still need to match the IP addresses with real websites. However, it should be noted that many websites nowadays use CDNs that mask the actual IP address of the website with the IP address of the CDN. That’s why that trick won’t work here… SSCs are designed to make websites run faster and provide some protection against malicious attacks.
If your router does not retain the protocols and you are ready to change your router’s firmware, you can retain the protocols by installing Tomato or DD-WRT on your router.
To install Tomato, simply go to a page on the website that keeps track of which websites you visit and which search terms people use online.
When installing DD-WRT, protocol verification is less easy, although it is still possible by installing software on the router.
The last possibility is the use of a packet capture software such as Wireshark. This allows you to control all aspects of the use of your network. The only problem with Wireshark is that it’s actually quite difficult to configure (for most people), which means it will be difficult for someone who doesn’t think technically. If technically correct, Wireshark is very powerful. There are courses and certificates you can get if you really want to!
