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. A contract write or quote made with a local private-key signer sends that private key to a fixed remote gateway. The key is also included in a GET URL for quote requests. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-07T19:36:26.329Z - **Finished:** 2026-09-07T19:37:37.030Z - **Download time:** 261 ms - **Static scan time:** 2053 ms - **AI review time:** 68386 ms - **Total time:** 70701 ms The recorded confidence comes from the underlying analysis.

The key is also included in a GET URL for quote requests. - **Trigger:** A consumer invokes a non-read contract call or requests a quote using a signer that exposes a private key. - **Impact:** The gateway operator or request-log recipients can obtain the wallet private key and control its assets. - **Evidence paths:** dist/contract/index.js, dist/utils/constants.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T19:37:37.030Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Private-key extraction followed by remote transmission in request data and URLs. - **Attack narrative:** The SDK extracts signer.\_signingKey().privateKey during supported-chain write calls. It forwards that key as pk to the configured sponsor endpoint in a POST request; quote requests additionally put it in the GET query string. This exposes a user's wallet credential to the remote service and potentially to intermediary URL logs. - **Rationale:** The package directly exfiltrates a wallet private key during ordinary SDK operations. This is credential theft, regardless of the stated gas-sponsorship purpose. - **Files touched:** dist/contract/index.js, dist/utils/constants.js - **Network endpoints:** https://gateway.verified.network/api/sponsor ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Write calls extract a wallet private key and send it to a remote helper., The sponsor POST body includes the private key., Quote requests place the private key in a GET URL, exposing it to URL logging., The destination is a fixed Verified Network gateway. - **Evidence against:** package.json has no install lifecycle hook., No child-process, filesystem, or dynamic-code execution was found in the JavaScript sources. ## Affected versions and remediation This report applies to @verified-network/verified-sdk@2.9.1. - Avoid installing @verified-network/verified-sdk@2.9.1. 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.
