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. The SDK automatically sends a signer private key, encrypted for a package-controlled public key, while processing contract calls and fee quotes. The matching private-key holder can decrypt it. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-13T20:24:01.245Z - **Finished:** 2026-09-13T20:25:10.760Z - **Download time:** 780 ms - **Static scan time:** 1497 ms - **AI review time:** 67237 ms - **Total time:** 69515 ms The recorded confidence comes from the underlying analysis.

The matching private-key holder can decrypt it. - **Trigger:** A consumer invokes a non-read contract call or requests a payment-token fee quote with a signer that exposes its private key. - **Impact:** The remote service can recover the wallet private key and take control of its funds and transactions. - **Evidence paths:** dist/contract/index.js, dist/utils/constants.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T20:25:10.760Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Extracts a wallet private key and transmits it encrypted to a fixed remote service. - **Attack narrative:** When a caller uses an SDK signer with an accessible private key, state-changing calls obtain that key, encrypt it to a hard-coded public key, and post it with transaction data to the sponsor gateway. Fee-quote requests repeat the extraction and include the encrypted key in the URL. Encryption protects it in transit but gives the corresponding private-key holder the ability to recover the wallet secret. - **Rationale:** The package contains a concrete credential-exfiltration path activated during normal SDK transaction and quote operations. Lack of install hooks does not mitigate remote recovery of consumer wallet private keys. - **Files touched:** dist/contract/index.js, dist/utils/constants.js - **Network endpoints:** gateway.verified.network ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Non-read contract calls extract the signer's private key., The key is encrypted to a package-embedded public key before transmission., The encrypted key and transaction data are sent to the fixed Verified Network gateway., Fee quotes also place the encrypted private key in a request URL. - **Evidence against:** package.json has no install lifecycle hook or self-dependency., No child-process, filesystem-write, or dynamic-code execution was found in inspected JavaScript. ## Affected versions and remediation This report applies to @verified-network/verified-sdk@2.9.6. - Avoid installing @verified-network/verified-sdk@2.9.6. 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.
