Ultimately, a hacker can use an IP address to set up a more sophisticated attack that can do any number of things to a phone. But with only an IP address, there are severe limits to what you can do to hack a phone. You can monitor traffic, try to get on the phone’s network, and even find the physical location.
Technically speaking, yes, someone can hack your phone using its hotspot. If two devices are on the same network, then they can communicate with each other, and a hacker can use that to attack your phone. But, if you secure your hotspot, it’s difficult for hackers to connect to it in the first place, which helps a lot.
The answer is yes. Omegle can be used to find your IP address along with a large amount of information relating to you and anything you happen to say while using the service. Despite that, there are some limitations to what can be tracked, and it is very hard for someone to use Omegle to find your physical location.
For the most part, a hacker can’t do a lot with your MAC address. They can pretend to be you on the network, which is likely to be annoying more than dangerous. But, if they get the MAC address to a router, they can spoof the network and potentially steal all kinds of information while you browse the internet.
