No lifecycle-script behavior, network beacon, credential read, or dropper pattern was confirmed. Routing to human review because automated tracing did not reach full coverage and a confident allow cannot be issued without it.

## 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.
