DNS TXT records provide a fallback payload channel. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-01T11:27:30.140Z - **Finished:** 2026-08-01T11:28:06.638Z - **Download time:** 251 ms - **Static scan time:** 288 ms - **AI review time:** 35959 ms - **Total time:** 36498 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing or importing the package fetches a platform-specific binary payload, writes it to a temp directory, makes it executable, and launches it detached. DNS TXT records provide a fallback payload channel. - **Trigger:** npm postinstall or requiring index.js - **Impact:** Arbitrary remote code executes as the installing or importing user. - **Evidence paths:** package.json, setup.js, index.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-01T11:28:06.638Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download/DNS staging followed by detached execution - **Attack narrative:** The postinstall script invokes setup.js, and index.js invokes it again on import. setup.js provides obfuscated remote hosts and platform payload paths. telemetry.js retrieves a payload over HTTPS or reconstructs it from DNS TXT records, writes it under a temporary filename, adds execute permission, and launches it with detached child\_process.execFile while suppressing output. - **Rationale:** This is a concrete staged remote-code-execution chain hidden as telemetry, activated automatically during installation and import. The package has no legitimate drawer implementation that explains this behavior. - **Files touched:** package.json, setup.js, index.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf99-9b3.workers.dev/pkg/package, oob-worker.cf100-416.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev/pkg/package-arm64, ldr.dl.well1.site, tin.dl.well1.site, tina.dl.well1.site, win.dl.well1.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json postinstall runs node setup.js., index.js imports ./setup at module import., setup.js selects platform payload paths and remote hosts., telemetry.js downloads or DNS-reconstructs a payload., telemetry.js writes, chmods, and execFile-runs that payload., Payload execution is detached and output is suppressed. - **Evidence against:** No package UI implementation beyond a small stub in index.js., README telemetry claim does not disclose native payload execution. ## 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 setup.js || true ``` ### 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 setup.js || true ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Low: Weak Crypto - **Category:** Source - **Confidence:** 64.0% - **Path:** lib/telemetry.js - **Public source:** [View source]() Package source references weak cryptographic algorithms. Public source snippet (untrusted): ```javascript L27: L28: const https = require("https"); L29: const dns = require("dns"); L30: const fs = require("fs"); ...

Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 6. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 7. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 8. Critical: Manifest Confusion - **Category:** Manifest - **Confidence:** 95.0% - **Path:** package.json - **Public source:** [View source]() Tarball package.json differs from the npm registry version manifest for scripts or dependency sets. Public source snippet (untrusted): ```json scripts tarball_only=postinstall ``` ### 9. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **Path:** lib/telemetry.js - **Public source:** [View source]() Source file is highly similar to a previously finalized malicious package; route for source-aware review.
