GoKawiilForensic tool ORISA recovers deleted AI chats from local Android apps
Georgia Tech researchers built a forensic tool called ORISA that reconstructs deleted conversations from on-device AI assistants running on Android phones. In a test using the ChatterUI app and a fictional assistant fed 100 facts, ORISA recovered 26 facts after deletion, compared with only 14 the assistant itself could still access before being wiped.
GoKawiil's interpretation of the reporting above, not reported fact.
The finding suggests that deleting a chat with a locally run AI assistant doesn't necessarily erase its traces from a phone's memory, which could undercut privacy assumptions tied to on-device processing. Because the technique requires forensic access to the device itself, it may be most relevant to scenarios like investigations or device resale rather than remote hacking, and it remains unclear whether cloud-based chatbot conversations are similarly recoverable.
- ORISA is a forensic tool from Georgia Tech researchers that reconstructs deleted AI chat data on Android devices.
- In testing with the ChatterUI app, it recovered 26 facts versus 14 still available to the original session.
- The method needs forensic device access and hasn't been shown to apply to cloud-based AI chatbots.
YubiKey 5C NFC Security Key — If deleted AI chats can still be forensically recovered from your device, it's a good reminder that true data security goes beyond just hitting delete. Adding a hardware security key like the YubiKey helps lock down your accounts with strong two-factor authentication, reducing the risk of unauthorized access to your sensitive data.
