shelf, good info I will just clarify a few things:
1. I never seem to understand this, if you do not exchange any files with the rest of the machines in the network, the only way i see it possible would be if the virus trick you to install some update to false program, but as long as you update only secure programs and have good antivirus, could a virus or any type of malicious software still manage to pass. My router it self was not compromised, but i connected a laptop i suspect was compromised to my home wifi network. All my other machines have firewalls, antivirus and malwarebyte protection.
2. So if one is good enough and had access to my home network, he could now steal cookies/credentials and all type of network traffic even far away from the range my router?
3. That cookie/credentials stealing could still happen even if you are not connected through the wifi, but through the cable? (the network traffic you do through the cable is still intercepted by the router, therefor it could be compromised, is that what you mean?)
4. I asked if all this stealing process is happening, does sites that use private credentials https (like faceook and gmail are supposed to be encrypted) are safe or a good enough hacker could still manage to steal and use them.
Also, if someone steals your cookies and credentials from your browser of facebook account for example, and he uses them on his device, will the information of his IP and device get recognized, or it will seem as its just you who is logged. I will try to explain, each week we download the data information of our company's facebook page and check for unknown IP's or devices that had logged in. We use this security method to prevent someone being messing around. If someone has stolen my network traffic like cookies and credentials and and now has access to our facebook page from his device and ip, but using the stolen credentials and cookies from my device, will the site recognize it as new device or it will not show his ip and device but only mine (that he stole) I hope you could realize what i am asking here. Because i have tested for example. when i switch from Wifi to mobile network on my tablet, when we later download the data is shows that the session was updated, and shows the new ip.
