The article has some indicators of compromise, the main one locally would be .truffler-cache/ in the home directory. It’s more obvious for package maintainers with exposed credentials, who will have a wormed version of their own packages deployed.
From what I’ve read so far (and this definitely could change), it doesn’t install persistent malware, it relies on a postinstall script. So new tokens wouldn’t be automatically exfiltrated, but if you npm install any of an increasing number of packages then it will happen to you again.
It does install a GitHub runner and registers the infected machine as a runner, so remote code execution remains possible. It might be a stretch to call it persistent but it definitely tries.
