aws-runtime-bridge: Install hook abuse – 4 npm versions blocked | LPM Firewall
Blocked & quarantined
Unconsented host-level package installation and network retrieval during dependency installation.
aws-runtime-bridge AgentsWorkStudio runtime bridge service for machine-level agent runtime integration
This report shows the evidence for aws-runtime-bridge@1.9.153 . 4 of 43 known versions are blocked or flagged. The newest version, 1.9.171, is allowed. See all versions .
scanned 1mo ago · by lpm-firewall-ai The package contains concrete, automatic install-time host mutation and network download behavior. Although the implementation is readable and no credential theft was found in the inspected hooks, this is unsafe lifecycle-hook abuse.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Installing the package on Linux as root when required tools are absent; postinstall runs on every install unless opted out.
Impact
Unconsented host-level package installation and network retrieval during dependency installation.
Mechanism
Lifecycle hooks invoke operating-system package managers and Playwright's browser installer.
Attack narrative
On installation, npm runs the package's preinstall and postinstall hooks. On a root Linux host with missing compiler tools, preinstall selects and runs a system package manager, including an index update where applicable. Postinstall invokes Playwright to download Chromium and, as root on Linux, asks it to install browser system dependencies. These host mutations occur automatically as part of installation rather than through an explicit package command.
AI rationale
The package contains concrete, automatic install-time host mutation and network download behavior. Although the implementation is readable and no credential theft was found in the inspected hooks, this is unsafe lifecycle-hook abuse.

public snapshot AI called this Malicious at 94.0% confidence as Malware with low false-positive risk.
Evidence for block
Installation automatically runs a preinstall script. That script invokes Linux package managers to install build tools when run as root. Postinstall automatically downloads Chromium and can request its system dependencies. Evidence against
The lifecycle scripts are readable and their actions are explicit. No credential collection or secret exfiltration was found in the inspected lifecycle scripts. Behavioral surface

Affected versions and remediation This report applies to aws-runtime-bridge@1.9.153 .
The versions list below shows the verdict for each recorded version.
Avoid installing aws-runtime-bridge@1.9.153. Remove it from direct dependencies and check your lockfile for transitive copies. Choose an independently verified alternative or release. This report does not establish that other versions are safe. If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. Evidence last updated: 2026-09-12 09:27:58.344Z (UTC) .
