The spy who hacked me - Measuring the security vulnerabilities of 3-D printing

The video discusses how common smartphones can hack 3D printers by measuring leaked energy and acoustic waves. Researchers highlight the security vulnerabilities of 3D printers, which could lead to intellectual property theft, especially as 3D printing becomes a multibillion-dollar industry. The method involves using a smartphone's sensors to infer the print nozzle's location, achieving high replication accuracy. To enhance security, increasing the distance from the printer, adjusting print speeds, and using shields are suggested solutions.

What potential threat does a common smartphone pose to 3D printers?

• It can slow down the printing process.

• It can hack the printer by measuring leaked energy and acoustic waves.

• It can change the color of the printed object.

• It can physically damage the printer.

How do researchers use a smartphone to hack a 3D printer?

• By installing malware on the printer.

• By using the smartphone's camera to capture the printing process.

• By connecting the smartphone directly to the printer.

• By programming the smartphone's sensors to measure electromagnetic energy and acoustic waves.

What accuracy rate did researchers achieve when replicating simple objects using a smartphone?

• 85%

• 80%

• 90%

• 94%

Which of the following is NOT a suggested method to improve 3D printer security?

• Increasing the distance from the printer.

• Programming the printer to operate at different speeds.

• Decreasing the print speed.

• Using acoustic and electromagnetic shields.

What happens to the accuracy of data collection when the distance from the 3D printer is doubled?

• It remains the same.

• It drops to 66%.

• It increases to 98%.

• It becomes negligible.
