No lifecycle hooks, hardcoded exfiltration endpoints, credential-path reads, or dropper patterns were surfaced. With no corroborating evidence of malicious behavior, a published block is not warranted; routing to human review so a reviewer can complete coverage and confirm benign intent or escalate if a specific harmful code path is identified.

## Source: google-open-source-security (a6c7977dbc054cdb7fe56da0d2fbd26e2a6fed695deb4263ccbf4adfedd86acb) 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.
