On require() of this package, index.js loads \_platform.js which assembles remote hostnames at runtime by concatenating fragmented string arrays to hide them from static scanners. The resolved hosts include oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, and tin/tina/ldr/win.dl.well1.site, with a DNS-TXT chunked base64 fallback channel... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-08-05T10:20:09.778Z - **Finished:** 2026-08-05T10:20:09.778Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to tinkoff-statist-browser-typed-client-mb.product.tgeofencing@20.9.6. - Avoid installing tinkoff-statist-browser-typed-client-mb.product.tgeofencing@20.9.6.

Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% On require() of this package, index.js loads \_platform.js which assembles remote hostnames at runtime by concatenating fragmented string arrays to hide them from static scanners. The resolved hosts include oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, and tin/tina/ldr/win.dl.well1.site, with a DNS-TXT chunked base64 fallback channel. The module downloads an opaque binary via https.get, writes it to /tmp or %TEMP% under disguised names impersonating.NET diagnostics (dotnet\_diag\_\.exe,.cache\_\), chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start /b. A sibling file lib/telemetry.js ships the same dropper shape (child\_process require string-split as require("child\_"+"process"), chmodSync via fs\["chmod"+"Sync"\], cp.spawn("/bin/sh", \["-c", filePath+" &"\])) as a staged secondary payload, though it is not reached from index.js in this version. The fetched-and-executed binaries, obfuscated destinations, disguised filenames, and DNS-TXT fallback do not match the package's declared Tgeofencing purpose. The package name also impersonates a Tinkoff internal-scope package, consistent with a dependency-confusion lure. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** tinkoff-statist-browser-typed-client-mb.product.tgeofencing - **Ecosystem:** npm - **Version:** 20.9.6 - **Version published:** 2026-08-02T11:16:51.802Z - **Package first seen:** 2026-08-05T10:20:09.778Z - **Package last seen:** 2026-09-19T06:56:08.056Z - **Known versions:** 2 - **Latest version:** 0.0.1-security - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]()
