LPM AI assessed this version as suspicious; the assessments disagree. Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree. OpenSSF/OSV advisory MAL-2026-13554 confirms this npm version as malicious. dolyame-ui-buttonstore@35.8.1 is a dropper. index.js unconditionally requires setup.js on load, which selects a per-platform binary path, fetches opaque bytes over HTTPS from hosts whose names are assembled at runtime by joining split character arrays (resolved destinations include oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev),... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-08-07T13:49:19.282Z - **Finished:** 2026-08-07T13:50:09.314Z - **Download time:** 255 ms - **Static scan time:** 226 ms - **AI review time:** 49551 ms - **Total time:** 50032 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** A hidden import-time payload downloader is present. It retrieves executable bytes, drops them to temporary storage, and launches them detached; however the preceding telemetry import appears syntactically invalid. - **Trigger:** Importing the package entrypoint; direct execution of setup.js would also activate it. - **Impact:** Arbitrary attacker-supplied native code execution. - **Evidence paths:** index.js, setup.js, lib/telemetry.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-07T13:50:09.314Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, and detached execution - **Rationale:** The downloader-and-executor is concrete malware behavior disguised as analytics, but the package entrypoint appears blocked by a syntax error in lib/telemetry.js. Treat it as an inert staged payload carrier rather than a confirmed active import-time compromise. - **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for AI warning decision:** index.js imports setup.js on package import., setup.js fetches platform-specific binary payloads from obfuscated hosts., setup.js decodes DNS TXT payload fallback and writes it to /var/tmp or Windows Temp., setup.js chmods the payload and launches it detached via shell/child\_process. - **Evidence against:** package.json has no lifecycle hooks., lib/telemetry.js contains a duplicated class declaration, so index.js likely fails parsing before setup.js is reached. ## Affected versions and remediation This report applies to dolyame-ui-buttonstore@35.8.1. - Avoid installing dolyame-ui-buttonstore@35.8.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
