Install-time code adds an Uncloud skill to existing third-party coding-agent skill directories. The inspected JavaScript shows no exfiltration, remote payload download, or destructive action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-08-11T01:47:23.476Z - **Finished:** 2026-08-11T01:48:01.089Z - **Download time:** 502 ms - **Static scan time:** 148 ms - **AI review time:** 36961 ms - **Total time:** 37613 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code adds an Uncloud skill to existing third-party coding-agent skill directories. The inspected JavaScript shows no exfiltration, remote payload download, or destructive action. - **Trigger:** npm postinstall - **Impact:** Can influence supported coding agents to invoke Uncloud deployment and management commands. - **Evidence paths:** package.json, bin/postinstall.js, lib/skill.js, bin/uncloud.js, skills/uncloud/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-11T01:48:01.089Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic installation of a bundled agent skill - **Rationale:** This is an unconsented install-time third-party agent-extension mutation, creating a real lifecycle risk. The narrowly scoped, first-party skill setup and absence of a concrete malicious chain support a warning rather than a block. - **Files touched:** bin/postinstall.js, lib/skill.js, skills/uncloud/SKILL.md, ~/.claude/skills/uncloud/SKILL.md, ~/.codex/skills/uncloud/SKILL.md, ~/.config/opencode/skills/uncloud/SKILL.md - **Network endpoints:** https://uncloud.club/cli/device, https://api.uncloud.club ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall., bin/postinstall.js automatically calls skill installation unless opted out., lib/skill.js writes SKILL.md into existing Claude Code, Codex, and opencode skill directories., Bundled skill directs agents to deploy and manage cloud resources. - **Evidence against:** Writes occur only under an already-existing agent directory., lib/skill.js avoids non-owned, edited, and symlinked destinations., Postinstall fetches no payload and contains no network or credential harvesting., bin/uncloud.js only launches a bundled platform binary on user invocation. ## 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 bin/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 bin/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. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. High: Sandbox Evasion Gated Capability - **Category:** Source - **Confidence:** 84.0% - **Path:** bin/uncloud.js - **Public source:** [View source]() Source gates dangerous network, credential, or execution behavior behind CI, host, platform, time, or geo fingerprint checks. Public source snippet (untrusted): ```javascript L10: L11: const { spawnSync } = require("child_process"); L12: const path = require("path"); ... L22: L23: const platform = process.platform; // darwin | linux L24: const arch = process.arch === "x64" ? "amd64" : process.arch; // arm64 passes through L25: L26: const binary = path.join(__dirname, "..", "vendor", `${platform}-${arch}`, "uncloud"); L27: ... L31: `Install directly instead:\n\n` + L32: ` curl -fsSL https://uncloud-cli.vercel.app/install.sh | sh\n` L33: ); ``` ### 7. Critical: Ai Agent Control Hijack - **Category:** Source - **Confidence:** 90.0% - **Path:** lib/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 L9: * Nothing is created speculatively. A directory is written only where that L10: * agent is already set up — installing uncloud never conjures a ~/.claude L11: * for someone who has never run Claude Code. ... L42: label: "Claude Code", L43: dir: path.join(home, ".claude"), L44: skills: path.join(home, ".claude", "skills"), L45: }, ... L48: label: "Codex", L49: dir: path.join(home, ".codex"), L50: skills: path.join(home, ".codex", "skills"), L51: }, ... L100: ``` ### 8. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 9. Medium: Ships Native Binary - **Category:** Artifact Inventory - **Confidence:** 75.0% - **Path:** vendor/darwin-amd64/uncloud - **Public source:** [View source]() Package ships native binary artifacts. Public source snippet (untrusted): ```text path = vendor/darwin-amd64/uncloud kind = native_binary sizeBytes = 7202608 magicHex = [redacted] ``` ### 10.
