bad USBs are SCARY!! (build one with a Raspberry Pi Pico for $8)
Source: YouTube · NetworkChuck · published Aug 20, 2021 · 21:05
This video explains how "Bad USB" devices, such as the USB Rubber Ducky, pose a significant security risk by tricking computers into automatically executing malicious code faster than a human can type.
Key Takeaways:
• The video defines a "Bad USB" as a device that mimics a Human Interface Device (HID) like a keyboard, exploiting the computer's inherent trust in human inputs 0:04-0:14.
• A live demonstration shows the USB Rubber Ducky successfully disabling Windows Defender and establishing a reverse shell within seconds of being plugged in 0:37-0:56.
• The presenter guides viewers on how to convert a Raspberry Pi Pico into a functional "Bad USB" by installing Circuit Python and the HID library 5:23-5:50.
• To mitigate risks, users should lock their screens when leaving and change registry settings so administrator prompts require passwords instead of simple "Yes" clicks 18:44-18:56.
Defending against these attacks requires strict user behavior, such as never plugging in unknown USB drives and always locking your computer when stepping away.

question for you what does this look like to you it's a usb flash drive right that's what most people think when they see something like this and honestly they're usually right but that is what makes this thing one of the most dangerous devices in hacking because this is not a usb flash drive this is what's called a bad usb it's designed by hackers to hack the computer it's plugged into this thing's crazy man it's incredibly dangerous it's shockingly effective like you want to see it real quick watch this got my crap top here i'm gonna hack my crap talk this is crazy watch this i'm just going to plug the usb in and then hands off i'm not doing anything watch look [Music] what's that oh it's disabling windows defender okay boom okay disable windows defender that's crazy again no hands look …
