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 using a signer that exposes a private key triggers transfer of that key, encrypted to a package-embedded recipient key, to the package's sponsorship service. The recipient can decrypt the credential and use it to control the wallet. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-12T19:46:41.184Z - **Finished:** 2026-09-12T19:47:49.010Z - **Download time:** 768 ms - **Static scan time:** 1494 ms - **AI review time:** 65563 ms - **Total time:** 67826 ms The recorded confidence comes from the underlying analysis.

The recipient can decrypt the credential and use it to control the wallet. - **Trigger:** A caller invokes a non-read contract function with a signer exposing a private key. - **Impact:** The remote service can recover and misuse the caller's wallet private key. - **Evidence paths:** dist/contract/index.js, dist/utils/constants.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T19:47:49.010Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Private-key extraction, recipient-key encryption, and remote transmission. - **Attack narrative:** When a consumer makes a write call, the SDK reads the private key from the supplied signer. It encrypts the key using a public key embedded by the package and posts the ciphertext and transaction to the fixed sponsorship endpoint. Encryption protects transit but gives the holder of the matching private key access to the wallet credential. The gasless path is always enabled, so the behavior is not limited to an explicit sponsorship opt-in. - **Rationale:** The package automatically extracts a caller's wallet private key and transmits it to a fixed vendor-controlled endpoint during normal contract writes. This is credential exfiltration despite the ciphertext being encrypted for the recipient. - **Files touched:** dist/contract/index.js, dist/utils/constants.js - **Network endpoints:** https://gateway.verified.network/api/sponsor ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The SDK extracts the private key from the supplied signer during ordinary write-contract calls., It encrypts that key with a package-embedded public key and sends the ciphertext with transaction data to a fixed remote service., Gasless routing is enabled for every chain, so this path is automatic when the signer exposes a private key. - **Evidence against:** The manifest has no preinstall, install, or postinstall hook., No shell execution, local file harvesting, or persistence code was found in the inspected JavaScript. ## Affected versions and remediation This report applies to @verified-network/verified-sdk@2.9.5. - Avoid installing @verified-network/verified-sdk@2.9.5. 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.
