This report shows the evidence for devplatform-react-hooks@35.5.7, the only known version.
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-code-execution chain unrelated to the advertised React hooks API. The absence of lifecycle scripts does not mitigate automatic execution when consumers import the package.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of devplatform-react-hooks through index.js.
Impact
Arbitrary attacker-controlled native code execution under the importing process user.
Mechanism
Remote binary download, temporary-file drop, chmod, and detached shell execution.
Attack narrative
The public entrypoint silently imports _init.js. On import, it selects a platform payload, retrieves it from obfuscated Workers hosts or DNS TXT records, drops it into a temp directory, marks it executable on Unix, and starts it via a detached shell or cmd.exe. No payload signature or hash validation exists.
AI rationale
This is a concrete import-time remote-code-execution chain unrelated to the advertised React hooks API. The absence of lifecycle scripts does not mitigate automatic execution when consumers import the package.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports ./_init during every package import.
- _init.js downloads platform-specific binary payloads over HTTPS or DNS TXT.
- _init.js writes payloads to /var/tmp or TEMP, makes Unix payloads executable, then launches them detached.
- Remote hosts are obfuscated by string concatenation and errors/logging are suppressed.
- Downloaded payload is not authenticated or integrity-checked.
Evidence against
- package.json has no npm lifecycle scripts.
- No credential harvesting or exfiltration was found in inspected entrypoint code.

Affected versions and remediation
This report applies to devplatform-react-hooks@35.5.7.
