Install-time execution automatically runs \`skyline setup\` through a package-aligned platform binary. The binary payload is not included here, so its setup-side effects cannot be established by source inspection. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 78.0% - **Started:** 2026-07-12T21:56:54.091Z - **Finished:** 2026-07-12T21:57:22.682Z - **Download time:** 503 ms - **Static scan time:** 13 ms - **AI review time:** 28075 ms - **Total time:** 28591 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time execution automatically runs \`skyline setup\` through a package-aligned platform binary. The binary payload is not included here, so its setup-side effects cannot be established by source inspection. - **Trigger:** npm postinstall when not running in CI and \`SKYLINE\_NO\_AUTO\_SETUP\` is unset - **Impact:** Potential first-party CLI/MCP extension setup or local configuration mutation; no confirmed exfiltration or destructive behavior. - **Evidence paths:** package.json, postinstall.js, bin.js - **Review source:** ai\_review - **Reviewed:** 2026-07-12T21:57:22.682Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall delegates to an opaque first-party native setup command - **Rationale:** The source establishes automatic install-time delegation to an uninspected native \`setup\` command, but contains no concrete malicious chain. Downgrade to warn until the platform binary’s setup behavior is reviewed. - **Files touched:** package.json, postinstall.js, bin.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** \`package.json\` defines \`postinstall: node postinstall.js\`., \`postinstall.js\` automatically invokes \`bin.js setup\` outside CI unless \`SKYLINE\_NO\_AUTO\_SETUP\` is set., \`bin.js\` resolves a first-party platform package and executes its native \`skyline\` binary with inherited stdio., The setup behavior resides in an unavailable platform binary, so its filesystem or agent-configuration effects cannot be verified from this package source. - **Evidence against:** The inspected JavaScript contains no network requests, credential harvesting, file reads beyond binary resolution, or exfiltration., No shell interpolation, eval-like execution, remote download, or destructive operation appears in \`postinstall.js\` or \`bin.js\`., The launcher uses a fixed allowlist of package-aligned \`@skylence-ai/skyline-\*\` platform dependencies. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node postinstall.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node postinstall.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 5. High: Known Malware Source Fingerprint Signature - **Category:** Supply Chain - **Confidence:** 94.0% - **Path:** bin.js - **Public source:** [View source]() Source fingerprint signature matches a known malicious package signature; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = malicious_source_fingerprint_signature signature = 202b3dfd3937dab6 signatureType = suspicious_hashes sourceLabel = final_verdict:malicious matchedPackage = @skylence-ai/skyline@1.0.70 matchedPath = bin.js matchedIdentity = npm:QHNreWxlbmNlLWFpL3NreWxpbmU:1.0.70 similarity = 1.000 shingleOverlap = 2 summary = package final verdict is malicious ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** @skylence-ai/skyline - **Ecosystem:** npm - **Version:** 1.0.72 - **License:** Apache-2.0 - **Version published:** 2026-07-12T21:53:38.229Z - **Package first seen:** 2026-07-01T13:28:02.061Z - **Package last seen:** 2026-08-15T19:27:10.519Z - **Known versions:** 23 - **Latest version:** 1.2.5 - **Appeal under review:** No ## References - [HTML security report]()
