npm package hijacking through domain takeover - how bad is this "new" attack?
When relying on a 3rd-party package from a non-commercial entity, there is always the risk of lack of support, especially when it comes to outdated packages and versions. If the package stops being maintained, nobody will implement a new feature we might need or fix a newly-discovered security vulnerability. Consider, for example, CVE-2019-17571. A critical remote code vulnerability which was never fixed in Log4j 1.x, since it was not supported anymore, and only fixed in Log4j 2.x.
