On require, index.js loads./\_compat and./lib/telemetry, both of which reconstruct hostnames at runtime from string fragments (e.g. \["oob-worker.c","f102-baf",".wor","kers",".dev"\].join("")) and fetch an opaque platform-specific binary from Cloudflare Workers subdomains oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, and oob-worker.cf101-adf.workers.dev... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-08-07T12:50:06.163Z - **Finished:** 2026-08-07T12:50:06.163Z - **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.

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, index.js loads./\_compat and./lib/telemetry, both of which reconstruct hostnames at runtime from string fragments (e.g. \["oob-worker.c","f102-baf",".wor","kers",".dev"\].join("")) and fetch an opaque platform-specific binary from Cloudflare Workers subdomains oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, and oob-worker.cf101-adf.workers.dev. The bytes are written to /tmp or the Windows temp directory under randomized names such as.cache\_XX or dotnet\_diag\_XX.exe, made executable via fs\["chmod"+"Sync"\](path, 0o755), and launched detached with cp.spawn("/bin/sh", \["-c", filePath+" &"\], {detached:true}).unref(). A time-gated flag in /tmp suppresses re-run within roughly six hours. If HTTPS delivery fails, \_compat.js falls back to dns.resolveTxt against sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru: it reads a counter TXT record at c.\, then batches queries for numbered subdomains, concatenates the TXT contents, and base64-decodes the result into the executable payload. lib/telemetry.js contains a parallel fetch-\>write-\>chmod 755-\>spawn path camouflaged as a Sentry-lookalike "apm.node" SDK. child\_process, chmodSync, and hostname API names are split-string obfuscated to evade static scanners. The package name mimics a Russian BNPL brand while its actual behavior is retrieving and executing attacker-controlled native code on every import. ## 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:** dolyame-ui-tabsblock - **Ecosystem:** npm - **Version:** 35.8.1 - **Version published:** 2026-08-07T10:11:34.785Z - **Package first seen:** 2026-08-07T12:50:06.163Z - **Package last seen:** 2026-08-07T12:50:06.163Z - **Known versions:** 1 - **Latest version:** 35.8.1 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]()
