augustdigital-sdk
JS SDK powering the August Digital ecosystem.
This report shows the evidence for augustdigital-sdk@8.20.1, the only known version.
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has a concrete, concealed install-time data-exfiltration path. The Sentry dynamic require is package-aligned and does not mitigate the lifecycle-hook behavior.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
npm lifecycle postinstall during package installation
Impact
Leaks local username, hostname, working directory, and install metadata.
Mechanism
silent HTTPS GET carrying encoded host and user metadata
Attack narrative
On npm installation, the postinstall inline Node command gathers npm package name/version, OS hostname, current OS username, current working directory, and a timestamp. It encodes these fields into an HTTPS request to build-metrics-collector.cdn-ops-health.workers.dev and suppresses all errors. This occurs without an explicit user action or documented SDK operation.
AI rationale
The package has a concrete, concealed install-time data-exfiltration path. The Sentry dynamic require is package-aligned and does not mitigate the lifecycle-hook behavior.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- package.json postinstall executes automatically during npm install.
- It sends hostname, OS username, current directory, package metadata, and timestamp.
- Data is sent to build-metrics-collector.cdn-ops-health.workers.dev, unrelated to the package's declared August Digital service URLs.
- Errors are silently suppressed, concealing collection failures.
Evidence against
- lib/core/analytics/sentry-runtime.js uses new Function only to select the installed Sentry runtime.
- No source evidence of payload download or AI-agent configuration writes.
