sme-rko-finance-front-payments-feed-display-listnpm
sme-rko-finance-front-payments-feed-display-list is a confirmed malicious npm package (MAL-2026-13662) 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-payments-feed-display-list (npm)
What this malware does
On require of the package's main module, compat.js unconditionally downloads a platform-specific executable and runs it. Destination hosts are assembled at runtime from split string arrays (e.g. ['oob-','worker.cf99-9b3.wo','rkers.de','v'].join('')) to evade static analysis, resolving to anonymous *.workers.dev subdomains that do not match any package publisher. The fetched bytes are written to a temp path under decoy names (dotnet_diag.exe,.cache_), chmodded 0755, and spawned detached via child_process.spawn ('/bin/sh' or 'cmd'), with a platform map covering linux/darwin/win32. When HTTP fetch fails, a fallback channel resolves DNS TXT records at c.<domain> under *.dl.wel1.ru for a chunk count, reassembles base64-encoded payload chunks from 0.<domain>, 1.<domain>,..., and executes the resulting binary. No hash or signature verification is performed. The package name presents as a benign finance-frontend UI component, which is inconsistent with the download-and-execute behavior.

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-payments-feed-display-list (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-payments-feed-display-list across your stack and pipelines.
If you installed it — respond
Remove sme-rko-finance-front-payments-feed-display-list 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-payments-feed-display-list 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-payments-feed-display-list 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.
