The paper can be found here https://arxiv.org/abs/1903.00446
You can find a demo of the SPOILER-leakage from JS in js_demo.
We use a counter based on shared array buffers, so make sure they are enabeled before running any tests:
firefox: about:config => javascript.options.shared_memory => true
chrome: chrome://flags/ => shared-array-buffer => true
opera: chrome://flags/ => shared-array-buffer => true
