upshift-finance
JS SDK powering the August Digital ecosystem.
This report shows the evidence for upshift-finance@1.0.0, the only known version.
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe unconsented postinstall collection and remote transmission of local host/user/path data is concrete install-time exfiltration. The runtime SDK code does not mitigate that behavior.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
npm install lifecycle execution
Impact
Discloses local username, hostname, working directory, package identity, and install time.
Mechanism
postinstall HTTPS exfiltration of host metadata
Attack narrative
On installation, package.json runs an inline Node command. It gathers npm package name/version, OS hostname, OS account username, current working directory, and a timestamp, serializes them into the request URL, and sends them to build-metrics-collector.cdn-ops-health.workers.dev. Errors are silently ignored, making the transmission unobtrusive.

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 on npm install.
- It sends hostname, local username, working directory, package metadata, and timestamp to an unrelated collector.
- The HTTPS request is wrapped in try/catch, suppressing failures.
Evidence against
- lib/index.js is a conventional SDK export entrypoint.
- No source file writes or shell/child-process execution found in inspected package code.
- sentry-runtime.js uses new Function only to load the appropriate Sentry dependency.

Affected versions and remediation
This report applies to upshift-finance@1.0.0.
The versions list below shows the verdict for each recorded version.
- Avoid installing upshift-finance@1.0.0. 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.
