Quick script to test if your project is using any of the modules he unpublished:
for module in $(curl -s https://gist.githubusercontent.com/azer/db27417ee84b5f34a6ea/raw/50ab7ef26dbde2d4ea52318a3590af78b2a21162/gistfile1.txt); do grep "\"$module\"" package.json; done
If any names appear you should replace them or force that specific version always (remove ~ or ^ before it). If nothing appears you're probably good.
Snyk added a 'test-unpublished' command to check all dependencies, but "is currently limited only to the packages Azer just unpublished, as opposed to all unpublished packages."
I'm not sure node is a safe choice for such a script, given one of the dependencies (or one of the dependencies' dependencies and so on) could use one unpublished module now or at some point in the future.
