In March, JFrog Security Research documented a malware campaign titled GhostClaw/GhostLoader. 

Since the original documentation of this campaign, Jamf Threat Labs examined multiple GitHub repositories associated with this same activity, including at least eight newly identified samples.

Jamf says this shift in distribution broadens the infection pool beyond developers installing packages from npm to include any user or automated workflow willing to execute commands sourced from online instructions. You can read the complete report here.
