I Built a $3 Rubber Ducky

Short summary

A developer built a Rubber Ducky (USB HID attack tool) for ₹150 using a DigiSpark ATtiny85 microcontroller, demonstrating how 10 seconds of physical access to an unlocked machine extracts sensitive data. The payload steals system info, network configs, and browser history without triggering Windows Defender. Physical security is the only defense—locking your screen (Win+L) is critical protection.

  • •Built a functioning USB attack tool for ₹150 using a DigiSpark microcontroller
  • •Payload extracts sensitive data in 8 seconds without triggering antivirus software
  • •Physical security (locking your screen) is the only defense against this attack vector
