AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package contains a concrete remote code execution chain hidden behind its public API. The lack of lifecycle hooks limits automatic installation execution but does not mitigate the malicious runtime behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-22T00:34:57.941Z - **Finished:** 2026-08-22T00:36:15.693Z - **Download time:** 251 ms - **Static scan time:** 90 ms - **AI review time:** 77411 ms - **Total time:** 77752 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Calling the exported middleware silently launches lib/caller.js detached. That child fetches attacker-controlled code from an obscured endpoint and executes it locally. - **Trigger:** Application calls the package's exported middleware factory. - **Impact:** Arbitrary code execution in the consuming user's environment. - **Evidence paths:** index.js, lib/caller.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-22T00:36:15.693Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Detached remote-payload fetch followed by dynamic Function execution. - **Attack narrative:** A consumer calling the exported middleware causes index.js to spawn lib/caller.js as a detached process. The child decodes a concealed JSONStorage URL, fetches a response field, constructs a function from that server-provided string, and invokes it with require access. The server can therefore supply arbitrary Node.js code after publication without modifying the package. - **Rationale:** The package contains a concrete remote code execution chain hidden behind its public API. The lack of lifecycle hooks limits automatic installation execution but does not mitigate the malicious runtime behavior. - **Files touched:** index.js, lib/caller.js - **Network endpoints:** https://api.jsonstorage.net/v1/json/2ef8c758-a96f-459e-b036-b3b90379a165/f89e8264-86c2-4684-94da-c3f82d59370f ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Exported middleware starts a detached child process., Child decodes an obscured remote URL and request header., Remote response field is passed to Function constructor and invoked with require., No install lifecycle hook; execution occurs when the package API is called. ## Affected versions and remediation This report applies to solidity-testing-utils@1.2.0. - Avoid installing solidity-testing-utils@1.2.0. 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.
