The upshift-finance npm package version 1.0.0 is a malicious repack of the legitimate @augustdigital/sdk package. It includes a postinstall script that silently sends host-specific information such as hostname, username, and working directory to an attacker-controlled Cloudflare Workers endpoint. The malicious behavior is limited to this data exfiltration beacon, with no additional payload or credential theft observed. This package was published by an unrelated freemail account shortly after two similarly named packages, indicating a brand hijack attempt. Hosts that installed this package have had identifying information disclosed to the attacker.
