Global installation automatically adds the package's uncloud skill to pre-existing third-party coding-agent skill directories. This is a package-owned extension setup, not a confirmed payload or exfiltration chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-10T17:07:45.561Z - **Finished:** 2026-08-10T17:08:21.410Z - **Download time:** 506 ms - **Static scan time:** 136 ms - **AI review time:** 35205 ms - **Total time:** 35849 ms ## Security analysis ### Published attack-surface review - **Summary:** Global installation automatically adds the package's uncloud skill to pre-existing third-party coding-agent skill directories. This is a package-owned extension setup, not a confirmed payload or exfiltration chain. - **Trigger:** npm postinstall, unless CI=true or UNCLOUD\_SKIP\_SKILL=1. - **Impact:** Can influence supported coding agents to invoke the uncloud CLI and its infrastructure-management capabilities. - **Evidence paths:** package.json, bin/postinstall.js, bin/uncloud.js, lib/skill.js, skills/uncloud/SKILL.md, vendor/linux-amd64/uncloud - **Review source:** ai\_review - **Reviewed:** 2026-08-10T17:08:21.410Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic first-party agent-skill installation - **Rationale:** This package performs an automatic lifecycle mutation of third-party agent extension directories, creating a real agent-extension risk. The source limits it to a marked first-party skill and contains no concrete malicious chain, so blocking is not justified. - **Files touched:** ~/.claude/skills/uncloud/SKILL.md, ~/.agents/skills/uncloud/SKILL.md, ~/.codex/skills/uncloud/SKILL.md, ~/.config/opencode/skills/uncloud/SKILL.md, vendor/darwin-amd64/uncloud, vendor/darwin-arm64/uncloud, vendor/linux-amd64/uncloud, vendor/linux-arm64/uncloud - **Network endpoints:** https://api.uncloud.club, https://api.uncloud.club/api/v1/auth/device/code, https://uncloud.club ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **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 outside CI., lib/skill.js writes SKILL.md into existing Claude Code, Codex, and opencode skill directories., The installed skill directs agents to operate deployment infrastructure and tokens., Bundled native binaries are stripped, limiting static source review. - **Evidence against:** Postinstall does not download or execute a remote payload., Skill writes occur only for agent directories that already exist., Existing unmarked/customized skills are preserved unless explicit --force is used., Source code shows no credential harvesting or network activity during install., Runtime launcher executes only the package-bundled platform binary with user arguments. ## 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"); ...

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. ...

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.
