High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% On require() of bigops-auth-interceptor@35.7.2, index.js loads \_vendor.js which selects a platform-specific binary URL, downloads bytes over HTTPS from one of four string-concatenation-obfuscated Cloudflare Workers mirrors (oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev), writes them to a temp path under a disguised name (dotnet\_diag\_\.exe on Windows,.cache\_\ on Linux), chmods 0755, and spawns the file detached via /bin/sh -c or cmd.exe. A DNS TXT-record fallback channel (c.\ returns a chunk count, then i.\ TXT records are concatenated and base64-decoded into the payload) is implemented against sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru, providing covert payload retrieval when HTTPS is blocked. A run-once marker file (.analytics\_state) prevents repeated execution. Destination hosts are unrelated to any legitimate publisher of the package's stated purpose; the fetched bytes are unpinned, unsigned, and platform-selected. ## 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:** bigops-auth-interceptor - **Ecosystem:** npm - **Version:** 35.7.2 - **Version published:** 2026-08-03T18:59:35.345Z - **Package first seen:** 2026-09-23T01:05:06.725Z - **Package last seen:** 2026-09-28T07:34:53.898Z - **Known versions:** 2 - **Latest version:** 0.0.1-security - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]()
