DOM Jungle - Can We Trust The UI?

links:none on file
slides:none on file

Claims a concrete defense: an open source project called lavadome encapsulates DOM subtrees to prevent JavaScript from reading secrets (demo: Metamask private key is visible to users but not discoverable by other scripts), implements Shadow DOM plus extra virtualization, and targets read-only protection not full write-blocking. It ships as experimental code, has a live hackable demo, and works against post-load supply‑chain scripts but fails against pre-run scripts or compromised build steps; browser integration remains a goal.
