Auto Attack Demo Video
Auto Attack Demo Video
Here we implemented the automatic interaction harness with the app, and launched the attack. The experiment is done by deploying the real-world app locally! The attacker can achieve the whole and persistent control of the app server!
rce.mp4OpenAI API Key Stealing Attack Demo Video
OpenAI API Key Stealing Attack Demo Video
We implemented the openai-api key stealing attack which is mentioned in Sec5.3.2, after the attacker modified the app code, once the user entered his API key, the key will be recorded and obtained by the attacker. The whole process even cannot be noticed by the victims. The experiment is done by deploying the real-world app locally!
key.mp4Real-world App Exploitation
Real-world App Exploitation
Due to the ethical consideration, we will not provide the exploitation screen-shots on real-world apps here. If you wanna see more about real-world impact, please contact lyutoon@gmail.com (this email will be public after the paper review).
Ethics and Disclosure
Ethics and Disclosure
We conducted some of our experiments on several commercial closed-source targets, but we do not disseminate the results nor implant any malicious feedback in the commercial targets. Also, we've already disclosed the vulnerabilities to the vendors via email, github-issue, etc.
