Install-time code installs a bundled Claude Code skill and replaces its versioned destination. No package-JavaScript network, credential harvesting, or exfiltration path was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-14T19:33:49.752Z - **Finished:** 2026-08-14T19:34:29.467Z - **Download time:** 259 ms - **Static scan time:** 51 ms - **AI review time:** 39404 ms - **Total time:** 39715 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code installs a bundled Claude Code skill and replaces its versioned destination. No package-JavaScript network, credential harvesting, or exfiltration path was found. - **Trigger:** npm postinstall or running the hscrape CLI - **Impact:** Mutates ~/.claude/skills/evo-scraper and can overwrite prior contents of that package-owned skill directory. - **Evidence paths:** package.json, lib/install-skill.js, hscrape.js, skill/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-14T19:34:29.467Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic first-party Claude Code skill deployment - **Rationale:** This is a real install-time AI-agent extension mutation, but it is a disclosed, narrowly named first-party skill setup with no concrete malicious chain in the inspected source. It warrants a lifecycle-risk warning rather than a block. - **Files touched:** lib/install-skill.js, skill/, ~/.claude/skills/evo-scraper, hscrape.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall runs a local installer automatically., Installer targets Claude Code's personal skills directory., Version changes recursively replace that skill directory., CLI invocation repeats the skill installation. - **Evidence against:** Installer contains no network or credential-reading logic., Bundled skill is a named evo-scraper extension, not a broad config rewrite., Launcher only resolves and executes the selected platform binary. ## 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 lib/install-skill.js ``` ### 2. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 3. Medium: Dynamic Require - **Category:** Source - **Confidence:** 75.0% - **Path:** hscrape.js - **Public source:** [View source]() Package source references dynamic require/import behavior.

Critical: Ai Agent Control Hijack - **Category:** Source - **Confidence:** 90.0% - **Path:** lib/install-skill.js - **Public source:** [View source]() Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel. Public source snippet (untrusted): ```javascript L3: // Copies the bundled evo-scraper Claude Code skill into the user's personal L4: // skills directory (~/.claude/skills/evo-scraper) so Claude Code discovers it. L5: // ... L22: function destDir() { L23: return path.join(os.homedir(), '.claude', 'skills', SKILL_NAME); L24: } ... L51: fs.rmSync(dest, { recursive: true, force: true }); L52: fs.mkdirSync(dest, { recursive: true }); L53: fs.cpSync(src, dest, { recursive: true }); // requires Node >= 16.7 L54: fs.writeFileSync(stamp, version); L55: } ``` ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 8. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ### 9. High: Known Malware Source Fingerprint Signature - **Category:** Supply Chain - **Confidence:** 94.0% - **Path:** hscrape.js - **Public source:** [View source]() Source fingerprint signature matches a known malicious package signature; route for source-aware review.

Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/install-skill.js - **Public source:** [View source]() Installer targets Claude Code's personal skills directory. Public source snippet (untrusted): ```javascript function destDir() { return path.join(os.homedir(), '.claude', 'skills', SKILL_NAME); } ``` ### 12. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/install-skill.js - **Public source:** [View source]() Version changes recursively replace that skill directory. Public source snippet (untrusted): ```javascript fs.rmSync(dest, { recursive: true, force: true }); fs.mkdirSync(dest, { recursive: true }); fs.cpSync(src, dest, { recursive: true }); // requires Node >= 16.7 fs.writeFileSync(stamp, version); ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 6 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 6 ### Published dependency entries - @evom/hscrape-darwin-arm64 0.2.15 (OptionalDependency) - @evom/hscrape-darwin-x64 0.2.15 (OptionalDependency) - @evom/hscrape-linux-arm64 0.2.15 (OptionalDependency) - @evom/hscrape-linux-x64 0.2.15 (OptionalDependency) - @evom/hscrape-win32-arm64 0.2.15 (OptionalDependency) - @evom/hscrape-win32-x64 0.2.15 (OptionalDependency) ## Package metadata - **Package:** hscrape - **Ecosystem:** npm - **Version:** 0.2.15 - **License:** UNLICENSED - **Version published:** 2026-08-14T19:28:29.497Z - **Package first seen:** 2026-07-13T16:05:07.949Z - **Package last seen:** 2026-08-21T01:32:57.504Z - **Known versions:** 7 - **Latest version:** 0.2.20 - **Appeal under review:** No - **Description:** Evo Headless Scraper CLI.
