Prompt Injection Via Road Signs

Interesting research: "CHAI: Command Hijacking Against Embodied AI." Abstract: Embodied Artificial Intelligence AI promises to handle edge cases in robotic vehicle systems where data is scarce by using common-sense reasoning grounded in perception and action to generalize beyond training...

Revisiting Adversarial Perception Attacks and Defense Methods on Autonomous Driving Systems

Autonomous driving systems ADS increasingly rely on deep learning-based perception models, which remain vulnerable to adversarial attacks. In this paper, we revisit adversarial attacks and defense methods, focusing on road sign recognition and lead object detection and prediction e.g., relative...

New Attack Against Self-Driving Car AI

This is another attack that convinces the AI to ignore road signs: Due to the way CMOS cameras operate, rapidly changing light from fast flashing diodes can be used to vary the color. For example, the shade of red on a stop sign could look different on each line depending on the time between the...

Confusing Self-Driving Cars by Altering Road Signs

Researchers found that they could confuse the road sign detection algorithms of self-driving cars by adding stickers to the signs on the road. They could, for example, cause a car to think that a stop sign is a 45 mph speed limit sign. The changes are subtle, though -- look at the photo from the...

"Warning Zombies Ahead!" - Road sign board Hacked

Drivers may have gotten a chuckle out of an electronic message board in Maine warning of zombies, but city officials were not amused. A Portland, Maine road sign is changed to a zombie warning on Wednesday, Oct. 10, 2012. It originally read "Night work 8 pm-6 am. Expect delays." An electronic...
