Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Runtime transaction and quote methods send an encrypted signer private key to a vendor-controlled sponsor service. This occurs without an explicit key-export parameter on the invoked contract operation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-12T15:14:10.599Z - **Finished:** 2026-09-12T15:15:19.019Z - **Download time:** 510 ms - **Static scan time:** 1508 ms - **AI review time:** 66401 ms - **Total time:** 68420 ms The recorded confidence comes from the underlying analysis.

This occurs without an explicit key-export parameter on the invoked contract operation. - **Trigger:** Calling a supported-chain contract operation or quote method with an Ethers signer that exposes a private key. - **Impact:** The service holding the corresponding private key can recover and use the wallet credential. - **Evidence paths:** dist/contract/index.js, dist/utils/constants.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T15:15:19.019Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Private-key extraction, bundled-key encryption, and remote transmission. - **Attack narrative:** A caller supplies a signer to an SDK contract wrapper. On supported chains, the wrapper reads the signer's private key, encrypts it to a public key embedded in the package, and sends the ciphertext to the configured sponsor gateway. The quote flow places that ciphertext in a GET query string. Encryption protects the key in transit but makes it recoverable by the holder of the paired private key, so it is credential exfiltration rather than local transaction signing. - **Rationale:** The package contains a concrete runtime path that exports wallet private keys to a remote service, including automatically during supported-chain contract calls. The absence of install hooks does not mitigate this credential-exfiltration behavior. - **Network endpoints:** gateway.verified.network ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Runtime code extracts a signer's private key and encrypts it with a bundled public key., Supported-chain contract calls automatically select the gasless path when a private-key signer is present., The encrypted private key is sent to the vendor gateway in a GET URL query parameter. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The compressed Yarn state file is not referenced by the manifest or runtime entry point. ## Affected versions and remediation This report applies to @verified-network/verified-sdk@2.9.4. - Avoid installing @verified-network/verified-sdk@2.9.4. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
