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 package entrypoint performs automatic, unrelated hostname disclosure through DNS on import. This is a concrete data-exfiltration behavior, so blocking publication is warranted. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-19T02:32:14.972Z - **Finished:** 2026-10-19T02:32:44.121Z - **Download time:** 1026 ms - **Static scan time:** 11 ms - **AI review time:** 28112 ms - **Total time:** 29149 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:** The library entrypoint automatically sends an encoded hostname prefix in a DNS query. - **Trigger:** A consumer imports lib/index.js. - **Impact:** The query discloses a machine identifier to a package-selected endpoint without a consent check. - **Evidence paths:** package.json, lib/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-19T02:32:44.121Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A timer runs after five seconds, reads part of the machine hostname, hex-encodes it, and uses it as a DNS query label. - **Attack narrative:** Importing the package schedules a DNS lookup. The lookup includes a hex-encoded prefix of the machine hostname at v1.kaspacore-lib.io, disclosing a machine identifier without a consent check. - **Rationale:** The package entrypoint performs automatic, unrelated hostname disclosure through DNS on import. This is a concrete data-exfiltration behavior, so blocking publication is warranted. - **Files touched:** lib/index.js - **Network endpoints:** v1.kaspacore-lib.io ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json selects lib/index.js as the package entrypoint., Importing the entrypoint schedules an automatic callback after five seconds., The callback encodes part of the machine hostname as a DNS query label and sends a lookup to v1.kaspacore-lib.io without a consent check. ## Affected versions and remediation This report applies to kaspacore-lib@1.0.1. - Avoid installing kaspacore-lib@1.0.1. 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.
