  • Imagine your computer is a big block of flats and your applications are all people who live in the building.

    Mail sent to the building address alone isn’t going to reach the intended recipient, because the postman doesn’t know what flat to post it to. So they need additional information such as ‘Flat 2C’

    That’s the basic concept of ports. It’s basically additional addressing information to allow your computer to direct internet traffic to the correct applications.

    When an application is actively listening on a port, it means that they are keeping an eye out for messages addressed to them, as designated by the port number. While an application is sending or receiving messages using a given port number, that port number is considered ‘open’.

    Now, all sorts of applications do all sorts of things. Some are for the public to use and there are some that are useful within trusted circles, but can be abused by malicious people if anyone in the world can send messages to it. Thus, we have a firewall, which acts as a gatekeeper. A firewall can ‘block’ a port, denying access to a given group of people, or ‘unblock’ it, allowing access.

    VPNs are a totally different thing. They are literally middlemen for your internet traffic. Instead of directly posting a message to somewhere and receiving a direct reply back, imagine you flew out to Italy to use a post box there and receive replies from there.

    That’s actually got a solid reason behind it.

    It’s because the OSK is just another program as far as Android is concerned. It can’t directly look into the application, per Android specifications, but it CAN record key presses, even for passwords. It even receives context hints based on the metadata on the input box, so it knows when you’re putting in a password. Then it can send your data off to unknown servers.



  • It does though. As someone who isn’t a US citizen, resident or visitor, he isn’t subject to US laws.

    What he is subject to is the laws of the country he was residing in, and any extradition treaties they have with the US. What he allegedly did was a crime there too, which is important as most countries will not extradite if what the subject did wasn’t criminal in both countries, if they were still in the request-recipient country at the time.
