AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The ESM runtime entry contains a concrete concealed payload-execution chain, not merely suspicious primitives. Lack of lifecycle hooks does not mitigate import-time arbitrary execution.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A consumer imports @syncraft-labs/core through its ESM export.

Impact

Arbitrary code execution in the importing user's environment.

Mechanism

Obfuscated remote payload retrieval followed by eval and detached child-process execution.

Attack narrative

The manifest directs ESM consumers to dist/index.js. A long, concealed statement inserted into isDevMode executes immediately during module evaluation, initializes network and compression modules, includes ETH_RPC_URL among its inputs, retrieves an obfuscated payload, then passes that payload to eval and a detached spawned process. This is unrelated to the advertised IndexedDB state library and provides arbitrary runtime code execution.

AI rationale

The ESM runtime entry contains a concrete concealed payload-execution chain, not merely suspicious primitives. Lack of lifecycle hooks does not mitigate import-time arbitrary execution.

Evidence

dist/index.jspackage.json

Decision evidence

public snapshot

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

Evidence for block

The ESM export is selected for import consumers and contains a hidden obfuscated loader on source line 5.
That loader imports HTTP, HTTPS, zlib, URL parsing, child-process spawning, and reads ETH_RPC_URL.
It obtains a remote payload then evaluates it and starts a detached hidden child process during module import.

Evidence against

package.json contains no preinstall, install, or postinstall hook.
The CommonJS entry is a normal IndexedDB state-store implementation without the injected loader.
