  • USBsamurai Demolab at DEF CON 29

    Tool or Project Name: USBsamurai

    Short Abstract:
    During this talk, after a bit of history of hardware implants, will be presented a new hacking device: USBsamurai. A remotely-controlled USB HID injecting cable that costs less than 10 EUR to produce from off-the-shelf components (a cable and a USB radio transceiver) that can be used to compromise targets remotely (i.e. over a 2.4GHz undetectable protocol) in the stealthiest way ever seen & also bypass Air-Gapped Environments like a boss!

    Extended Version:
    During the last years, hardware implants have become a popular attack vector in air-gapped environments such as industrial networks: Stuxnet (2010), Operation Copperfield (2017), and the recent ransomware attack that has led to a shutdown in a US natural gas facility are only some notable cases. In parallel, in an effort to raise the bar of red-teaming operations, security researchers have been designing and releasing powerful open-source devices with the intent to make Red-Teaming operations even more interesting and disruptive. Smoothing the path to new TTPs and improving old ones. As a result, hardware implants should always be included in the threat modeling of an industrial facility.

    This presentation will be quite technical, tailored for an ICS security audience. Come to this talk to start preparing for the next wave of attacks that can pass undetected by most of the existing security solutions available on the market.

    Finally, I'll conclude the talk with practical, actionable countermeasures to prevent and detect HID attacks, and conclude by explaining how to approach a forensics analysis in presence of USB implants.

    Short Developer Bio:
    Luca Bongiorni is working as Head of Offensive Security. He is also actively involved in InfoSec where his main fields of research are: Radio Networks, Reverse Engineering, Hardware Hacking, Internet of Things, and Physical Security. He also loves to share his knowledge and present some cool projects at security conferences around the globe.

    Detailed Explanation of Tool:
    USBsamurai is a DIY hardware implant disguised as USB cable that allows to remotely inject over an undetectable RF channel an agent in memory that allows a remote threat actor to get a realtime shell over a target that can also be air-gapped. In practice a nightmare for any BlueTeam out there. Have you ever seen an USB cable that can bypass an air-gapped system and return a live remote-shell over an undetectable RF channel?

    Target Audience:
    Offense, Hardware, ICS

    Create awareness on Hardware Implants. The real ones. Not the grain of rice from Bloomberg's article. ;]

    During the years I have tested multiple DLP solutions out there claiming to sanitize and protect assets from USB-related threats. Surprisingly, most of the time vendors kinda lie (or... saying in a more polite way... they forget about HID class of devices).

    Security Officers MUST understand that hardware implants exist and they don't cost anymore like 10,000 $USD like NSA's TAO FIREWALK implant!

    Finally, in pure DEF CON style, sharing how to create an offensive hardware implant out of a 10$ USB dongle from a commercial mouse, it is always a good way to spread knowledge among fellow hackers. :)
