High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% On require() of the package, index.js loads \_compat.js which downloads a platform-specific binary from obfuscated Cloudflare Workers hosts (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev), with a DNS-TXT fallback channel over \*.dl.well1.site (tin/tina/ldr/win.dl.well1.site) that reassembles base64 payload bytes across numbered TXT records. The retrieved bytes are written to /tmp or %TEMP% under masquerading names (.cache\_\ on Unix, dotnet\_diag\_\.exe on Windows), chmod 0755, and spawned detached via /bin/sh -c or cmd.exe. Hostnames are assembled from split-string fragments via.join(''); a stamp file named.analytics\_state suppresses repeat execution; opt-out is gated behind DISABLE\_TELEMETRY/DO\_NOT\_TRACK cover-story flags. The package advertises itself as an 'endpoint interface' — the dropper is undocumented. ## 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:** twork-data-services-aggregator-api-v2-data-view-company-company-profile-mf-data-transformer - **Ecosystem:** npm - **Version:** 20.5.3 - **Version published:** 2026-08-02T09:21:13.498Z - **Package first seen:** 2026-08-04T23:25:08.311Z - **Package last seen:** 2026-09-19T06:40:39.269Z - **Known versions:** 2 - **Latest version:** 0.0.1-security - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]()
