The ESM build dist/index.js of @syncraft-labs/[email protected] contains a heavily obfuscated payload injected alongside the otherwise-legitimate Vue plugin source. The obfuscated region uses an obfuscator.io-style rotating string array (303 entries, _0x240a/_0x4963 decoders) and opaque predicates to hide a loader that requires http/https/zlib and child_process.spawn, queries Ethereum RPC endpoints (publicnode.com/ethereum-rpc, drpc.org/eth, blockscout) and an Etherscan-style txlist endpoint for the hardcoded address 0xa322E5f3..., decodes base64/gzip content from returned transaction data, and passes it to child_process.spawn. This is the EtherHiding blockchain-hosted C2 dropper pattern: any consumer importing @syncraft-labs/vue via ESM (the package's `module` entry) resolves an attacker-controlled runtime payload from Ethereum transactions and executes it, yielding remote code execution on the host performing the import. The CJS build and sourcemap are clean, indicating the ESM artifact was tampered after build to smuggle the loader while leaving createSyncraft/useSync and the vue/@syncraft-labs/core imports intact.
