The new USB Rubber Ducky is more dangerous than ever

The USB Rubber Ducky is again with a vengeance.

The much-loved hacking device has a new incarnation, launched to coincide with the Def Con hacking convention this yr, and creator Darren Kitchen was readily available to clarify it to The Verge. We examined out a few of the new options and located that the most recent version is more dangerous than ever.

What is it?

To the human eye, the USB Rubber Ducky seems to be like an unremarkable USB flash drive. Plug it into a pc, although, and the machine sees it as a USB keyboard — which implies it accepts keystroke instructions from the machine simply as if an individual was typing them in.

“All the things it varieties is trusted to the identical diploma because the person is trusted,” Kitchen informed me, “so it takes benefit of the belief mannequin in-built, the place computer systems have been taught to belief a human. And a pc is aware of {that a} human usually communicates with it via clicking and typing.”

The unique Rubber Ducky was launched over 10 years in the past and have become a fan favourite amongst hackers (it was even featured in a Mr. Robotic scene). There have been various incremental updates since then, however the latest Rubber Ducky makes a leap ahead with a set of new options that make it far more versatile and highly effective than earlier than.

What can it do?

With the fitting strategy, the probabilities are virtually countless.

Already, earlier variations of the Rubber Ducky may perform assaults like making a faux Home windows pop-up field to reap a person’s login credentials or inflicting Chrome to ship all saved passwords to an attacker’s webserver. However these assaults needed to be rigorously crafted for particular working methods and software program variations and lacked the flexibleness to work throughout platforms.

The latest Rubber Ducky goals to beat these limitations. It ships with a significant improve to the DuckyScript programming language, which is used to create the instructions that the Rubber Ducky will enter right into a goal machine. Whereas earlier variations had been largely restricted to writing keystroke sequences, DuckyScript 3.0 is a feature-rich language, letting customers write capabilities, retailer variables, and use logic movement controls (i.e., if this… then that).

Which means, for instance, the new Ducky can run a take a look at to see if it’s plugged right into a Home windows or Mac machine and conditionally execute code acceptable to every one or disable itself if it has been linked to the fallacious goal. It can also generate pseudorandom numbers and use them so as to add variable delay between keystrokes for a more human impact.

Maybe most impressively, it might probably steal information from a goal machine by encoding it in binary format and transmitting it via the indicators meant to inform a keyboard when the CapsLock or NumLock LEDs ought to gentle up. With this methodology, an attacker may plug it in for just a few seconds, inform somebody, “Sorry, I assume that USB drive is damaged,” and take it again with all their passwords saved.

How a lot of a risk is it?

Briefly, it may very well be an enormous one, however the want for bodily machine entry means most individuals aren’t vulnerable to being a goal.

In accordance with Kitchen, the new Rubber Ducky was his firm’s most in-demand product at Def Con, and the five hundred or so items that Hak5 dropped at the convention offered out on the primary day. Secure to say, many tons of of hackers have one already, and demand will seemingly proceed for some time.

It additionally comes with an on-line growth suite, which can be utilized to put in writing and compile assault payloads, then load them onto the machine. And it’s straightforward for customers of the product to attach with a broader neighborhood: a “payload hub” part of the positioning makes it straightforward for hackers to share what they’ve created, and the Hak5 Discord is additionally lively with dialog and useful ideas.

At a value of $59.99 per unit, it’s too costly for most individuals to distribute in bulk — so it’s unlikely that somebody will depart a handful of them scattered in your favourite cafe until it’s identified to be a hangout place for delicate targets. That mentioned, if you happen to’re planning to plug in a USB machine that you simply discovered mendacity out in a public place, assume twice about it…

Might I take advantage of it myself?

The machine is pretty easy to make use of, however if you happen to don’t have any expertise in writing or debugging code, there are some things that might journey you up. In testing on a Mac, for some time, I couldn’t get the Ducky to enter the F4 key to open the launchpad, however I mounted it after making it determine itself with a special Apple keyboard machine ID.

From that time, I used to be in a position to write a script in order that, when plugged in, the Ducky would mechanically launch Chrome, open a new browser window, navigate to The Verge’s homepage, then shortly shut it once more — all with no enter from the laptop computer person. Not dangerous for only a few hours’ testing and one thing that may very well be simply modified to do one thing more nefarious than browse expertise information.
