No concrete installer-harm signals were identified in this package version. No lifecycle scripts, hardcoded network destinations, credential-path reads, or obfuscated payloads have been cited. Coverage of the package contents was incomplete, so a maintainer review is recommended before establishing a final disposition.

The Miasma malware is a self-propagating worm that spreads across the npm registry by abusing weaponized `binding.gyp` files to achieve execution during package installation, bypassing security tools that only inspect package lifecycle scripts. Upon execution, the malware attempts to exfiltrate credentials and OIDC tokens for various cloud and registry services, and propagates by compromising other packages managed by the stolen accounts or committing backdoor files to GitHub repositories.
