dolyame-ui-radionpm
dolyame-ui-radio is a confirmed malicious npm package (MAL-2026-13177) that executes malicious code on install (malicious version 35.2.2). Do not install it — remove it immediately and rotate any exposed credentials.

What this malware does
[email protected] is a dropper disguised as a UI/telemetry package. index.js unconditionally require()s./adapter.js, which on module load downloads a platform-specific binary from string-split-obfuscated Cloudflare Workers hostnames (oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev) with DNS-TXT fallback via sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru. The fetched bytes are written to /tmp or %TEMP% under masquerading names (dotnet_diag<hex>.exe on Windows,.cache_<hex> on Unix), chmod 0755'd, and spawned detached via /bin/sh -c or cmd. Destination hostnames are assembled from split-and-joined string fragments; cache paths and opt-out env-var names (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK,.analytics_state) present a telemetry cover story that does not match the observed drop-and-exec behavior. A second copy of the same drop-and-exec logic (base64 chunk assembly, chmodSync 0755, spawn /bin/sh) is bundled in lib/telemetry.js, unreached in this version's import graph but shipped in the tarball. Any require() or import of this package executes attacker-controlled native code on the installer's host.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for dolyame-ui-radio (version 35.2.2). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging dolyame-ui-radio across your stack and pipelines.
If you installed it — respond
Remove dolyame-ui-radio from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If dolyame-ui-radio was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks dolyame-ui-radio before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
