It fetches a binary or DNS-encoded payload, writes it to temporary storage, executes it detached, and deletes it shortly after. - **Trigger:** Any runtime import or require of the package. - **Impact:** Arbitrary code execution under the importing process user. - **Evidence paths:** index.js, setup.js, package.json, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-01T11:35:18.846Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download and detached execution. - **Attack narrative:** The main module silently imports setup.js. On first import, setup.js selects a platform payload, retrieves it from obfuscated remote hosts or a DNS TXT fallback, writes it to a temporary executable file, sets executable permissions where needed, and starts it detached with hidden output. The claimed telemetry documentation does not match this arbitrary executable loader. - **Rationale:** This is a concrete import-time staged-payload execution chain, not ordinary telemetry. The absence of lifecycle hooks does not mitigate execution when consumers import the package. - **Files touched:** index.js, setup.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **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, tin.dl.well1.site, tina.dl.well1.site, ldr.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:** index.js imports ./setup at package import time., setup.js downloads platform binaries from obfuscated workers.dev hosts., setup.js falls back to DNS TXT payloads from well1.site domains., setup.js writes, chmods, detached-executes, then deletes the downloaded binary., The temporary analytics stamp suppresses repeat execution. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting is present in the inspected files. ## Public findings ### 1. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 2. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 3. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 4. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **Path:** setup.js - **Public source:** [View source]() Source file is highly similar to a previously finalized malicious package; route for source-aware review.

High: Known Malware Source Fingerprint Signature - **Category:** Supply Chain - **Confidence:** 94.0% - **Path:** setup.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 = 405ba70d706ba63c signatureType = suspicious_hashes sourceLabel = final_verdict:malicious matchedPackage = arbocrate-sla-prober-arbocrate-sla-prober-core@7.5.9 matchedPath = setup.js matchedIdentity = npm:[redacted]:7.5.9 similarity = 1.000 shingleOverlap = 2 summary = package final verdict is malicious ``` ### 6. High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** setup.js - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.
