Hopefully not to late to learn... ;-)

Many people considder USB to be some Serial cable like they used to have for Modems, Printers etc.
USB really is a multi-drop networking standard. And it provides for all kind of adapters like Storage Nodes, Network "routers" (=Usb Ethernet ...), Network camera's (photo equipment), ...
So USB sticks are more like a NAS on a private network then a Disk onto a Pata/Sata cable.  The difference is they have no configuration items on most USB equipment.
(Rather like the original SCSI standard, only serial).

The Poison Tap (short version) provides a network adapter, with DHCP and it will provision a network with netmask 0 (so ALL packets sent by your system [ except for the local network you PC is connected to ] go to the PoisonTap..). Which also runs a transparant proxy to hijack connections.  and will inject code back into the browser to redirect ALL access through another public site. After the PoisonTap is removed the attack still persists. Allowing an attacker to keep on tapping authentication data.

Warning: If your device uses WiFi, it's at risk!
News broke today about the Krack Attack, a new cyber threat that can decrypt and potentially view everything users are doing online. The Krack Attack preys on a weakness in WPA2 protocol. Hackers near the vulnerable devices (Android and Linux are at greatest risk) can retrieve sensitive user data and information.
Steps to Protect:
1. Apply patches as they become available. For phones and computers, the patches will come in the usual update format. For wifi routers, the manufacturer's website will have the patches.
2. Don't use public WiFi, especially for sharing or sending any sensitive information.
3. Double check that you are browsing with HTTPS. If you are unsure, install this plug-in to encrypt your communications with major websites and make your browsing more secure. https://www.eff.org/https-everywhere
4. Otherwise, use Ethernet.

Amazon recently filed a patent for a system wherein while someone is shopping inside of a store, and using that store's wifi connection, the store owner is able to inspect the wifi packets to see if a competitive product is being viewed and then issue a "control" action in response.

Basically if you want to price shop while inside of a retailer, they'll be able to block the action from happening.

With mobile data plans so affordable these days, combined with the great speeds 4G provides, I don't get why people still auto connect to public wifi hotspots at all? They're fraught with hackers and an easy way of getting yourself infected with something.  

Never use them myself so the expensive patent application is a waste of money on Amazon's part so far as I'm concerned.

In most of the big box stores, I lose my LTE signal and have to use their wi-fi. I use a secure vpn when connecting, but your average consumer just blindly connects.
