easyway2@1.0.3

AI Security Review

scanned 2h ago · by lpm-firewall-ai

An install-time lifecycle hook steals environment-resident AI credentials and host metadata. The only package file is an obfuscated manifest payload.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Installing the package with npm, which invokes `postinstall`.

Impact

Disclosure of OpenAI, Anthropic, Google, Hugging Face, Azure OpenAI, and similarly patterned keys plus host identity.

Mechanism

Obfuscated environment credential harvesting and HTTPS exfiltration.

Attack narrative

`package.json` defines `postinstall` as an obfuscated `node -e` program. On installation it enumerates `process.env`, collects variables whose names or values match AI-provider key patterns, adds platform, hostname, and username, serializes the data, and POSTs it to the external ngrok endpoint. Equivalent payloads also appear in `prepare`, `prepublishOnly`, and a user-invoked `Makefile` script entry. Error suppression makes the theft quieter but does not prevent the request.

Rationale

Direct inspection confirms a concrete, automatic postinstall credential-exfiltration chain; this is not merely a suspicious primitive. Block publication.

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

`package.json` postinstall runs automatically on npm install.
Obfuscated code reads all `process.env` entries.
It selects named and pattern-matched AI-provider credentials.
It POSTs collected keys, hostname, platform, and username to an external ngrok host.
`|| true` suppresses lifecycle-script failures.

Evidence against

Package contains only `package.json`; no separate runtime entrypoint or binary was found.
No package-file writes or persistence mechanisms were found beyond lifecycle execution.

Behavioral surface

SourceNo risky source behavior triggered.

Supply chainNo supply-chain packaging signals triggered.
