Installation triggers the package's \`setup\` subcommand through a platform binary. Documentation describes a Skyline daemon autostart and best-effort Skyline agent-plugin installation; binary internals are not included. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 83.0% - **Started:** 2026-07-10T16:54:55.076Z - **Finished:** 2026-07-10T16:55:29.059Z - **Download time:** 510 ms - **Static scan time:** 13 ms - **AI review time:** 33459 ms - **Total time:** 33983 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation triggers the package's \`setup\` subcommand through a platform binary. Documentation describes a Skyline daemon autostart and best-effort Skyline agent-plugin installation; binary internals are not included. - **Trigger:** npm postinstall when neither \`CI\` nor \`SKYLINE\_NO\_AUTO\_SETUP\` is set - **Impact:** May persist a Skyline daemon and configure Skyline marketplace plugins on the installing user's machine; no exfiltration or destructive behavior is confirmed from available source. - **Evidence paths:** package.json, postinstall.js, bin.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-10T16:55:29.059Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall launches package-owned setup through a selected native binary - **Rationale:** Visible source establishes an install-time first-party daemon and AI-agent plugin setup action, but no concrete credential theft, exfiltration, remote payload execution, destructive action, or foreign/broad agent-control hijack. The absent platform binaries leave a real lifecycle risk requiring a warning. - **Files touched:** package.json, postinstall.js, bin.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** \`package.json\` defines \`postinstall\`., \`postinstall.js\` invokes \`bin.js setup\` unless CI/opt-out is set., \`README.md\` states setup installs an autostart daemon and agent plugins., \`bin.js\` dispatches to platform-specific opaque native binaries. - **Evidence against:** No network, credential collection, filesystem writes, eval, or payload download exists in inspected JavaScript., Postinstall only invokes the package's own \`setup\` command and logs failures., The documented action is Skyline-owned daemon/plugin setup, not a foreign control-surface mutation., No hidden files or additional source files were present. ## 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@1.0.57 matchedPath = bin.js matchedIdentity = npm:QHNreWxlbmNlLWFpL3NreWxpbmU:1.0.57 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:** 1.0.62 - **License:** Apache-2.0 - **Version published:** 2026-07-10T16:53:00.738Z - **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]()
