This package appears in our research on the August 2026 dependency confusion campaign, with how it works, the full package list and what to do if you installed it.
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote payload execution chain unrelated to the advertised React type/component package. The lack of install hooks does not mitigate execution on ordinary package use.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Any runtime require/import of index.js, including the README's documented require call.
Impact
Arbitrary code execution as the consuming application's user.
Mechanism
import-time remote binary download, drop, chmod, and detached execution
Attack narrative
Requiring index.js silently imports _helpers.js. Its top-level run() downloads a binary selected by OS/architecture from obfuscated Workers hosts, falling back to base64 DNS TXT data from .ru domains. It writes the bytes to a temporary executable path and launches it detached with /bin/sh or cmd.exe; no hash, signature, or user opt-in is present.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _helpers.js on every package import.
- _helpers.js downloads platform-specific binary content from remote mirrors or DNS TXT records.
- _helpers.js writes the payload to /var/tmp or Windows Temp, marks it executable on Unix, then launches it detached via shell/cmd.
- Remote endpoints are obfuscated through string concatenation and payloads have no integrity verification.
- No lifecycle hook is needed: requiring the documented package entrypoint triggers the chain.
Evidence against
- package.json contains no npm lifecycle scripts.
- lib/telemetry.js is not imported by the package entrypoint; the active malicious chain is _helpers.js.
