sme-rko-finance-front-operations-feed-implnpm
sme-rko-finance-front-operations-feed-impl is a confirmed malicious npm package (MAL-2026-13636) that executes malicious code on install (malicious version 35.8.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in sme-rko-finance-front-operations-feed-impl (npm)
What this malware does
On require(), adapter.js and lib/telemetry.js assemble Cloudflare Workers hostnames from string-split arrays (oob-worker.cf101-adf.workers.dev, cf99-9b3.workers.dev, cf103-070.workers.dev, cf100-416.workers.dev) joined at runtime, download a platform-specific binary payload, write it under /tmp or %TEMP% with a disguised name (dotnet_diag<rand>.exe on Windows; hidden.cache_<rand> on Unix), chmod 0755 (via the concatenated property name fs['chmod'+'Sync']), and spawn it detached through cmd.exe or /bin/sh -c '<path> &' with detached:true and unref(). When HTTPS retrieval fails, a DNS-based staging channel resolves TXT records on sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru — reading a chunk count from c.<domain> and reconstructing a base64 payload from 0.<domain>..N.<domain> TXT records. The require of child_process is split as require("child_"+"process") and the module is dressed up with an analytics_state cover-story marker resembling a Sentry-like telemetry SDK. Two redundant dropper paths execute on import: _adapter.js and the main entry lib/telemetry.js.

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 sme-rko-finance-front-operations-feed-impl (version 35.8.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging sme-rko-finance-front-operations-feed-impl across your stack and pipelines.
If you installed it — respond
Remove sme-rko-finance-front-operations-feed-impl 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 sme-rko-finance-front-operations-feed-impl 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 sme-rko-finance-front-operations-feed-impl 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.
