twork-data-services-aggregator-sme-task-infonpm
twork-data-services-aggregator-sme-task-info is a confirmed malicious npm package (MAL-2026-12288) that executes malicious code on install (malicious version 20.3.1). Do not install it — remove it immediately and rotate any exposed credentials.

What this malware does
On require of this package, index.js loads runtime.js which asynchronously fetches a platform-specific binary from string-concatenation-obfuscated hosts (oob-worker.cf100-cf103-*.workers.dev, with a DNS-TXT chunked base64 fallback via tin/tina/ldr/win.dl.well1.site), writes it to /tmp as.cache<rand> or to %TEMP% as dotnet_diag_<rand>.exe, chmods it 755, and spawns it detached via /bin/sh -c or cmd.exe /c start. Destination hostnames and DNS resolvers are assembled at runtime via.join() over split string fragments to evade static inspection. No hash or signature verification is performed on the fetched bytes. A second, functionally equivalent dropper is shipped in lib/telemetry.js (mislabeled 'Analytics SDK'): base64 chunk reassembly, split-string require("child_"+"process"), fs["chmod"+"Sync"](path, 0o755), and cp.spawn("/bin/sh", ["-c", filePath+" &"], {detached:true}). Package name masquerades as an enterprise data-services utility; behavior is a load-time remote-code-execution dropper.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

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 twork-data-services-aggregator-sme-task-info (version 20.3.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging twork-data-services-aggregator-sme-task-info across your stack and pipelines.
If you installed it — respond
Remove twork-data-services-aggregator-sme-task-info 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 twork-data-services-aggregator-sme-task-info 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 twork-data-services-aggregator-sme-task-info 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.
