4Weaponizing image scaling against production AI systems
- A security vulnerability in AI systems allows attackers to hide malicious prompts in images that become visible when scaled down. This can lead to data theft when processed by systems like Google Gemini CLI. The researchers developed a tool called Anamorpher to demonstrate and study these attacks.
Hidden text in images
Discussion about how text can be hidden in images through downscaling tricks and aliasing effects, making it invisible to humans but readable by AI models, creating a security vulnerability.Security implications
Concerns about LLMs' fundamental security flaws due to inability to distinguish between instructions and data, leading to prompt injection vulnerabilities that can't be fully prevented through training.System design solutions
Debate around potential architectural solutions like task-specific layering, proper image scaling algorithms, and sandboxing to mitigate prompt injection risks, though no clear consensus on effectiveness.
5Waymo granted permit to begin testing in New York City
- Waymo, Alphabet's autonomous vehicle subsidiary, received its first permit from New York City to test self-driving cars. Starting with eight vehicles in Manhattan and Brooklyn through September, the testing requires a driver behind the wheel. This expansion follows Waymo's growth in other major U.S. cities and its milestone of 10 million robotaxi trips.
