twork-data-services-ng14-aggregator-api-v2-data-view-user-b2b-create-deal-mf-config is a confirmed malicious npm package (MAL-2026-12294) that executes malicious code on install (malicious version 20.6.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in twork-data-services-ng14-aggregator-api-v2-data-view-user-b2b-create-deal-mf-config (npm)
What this malware does
On require(), index.js loads adapter.js, which downloads a platform-specific binary from Cloudflare Workers hosts under oob-worker.cf10x-*.workers.dev assembled by array-join string concatenation, writes it to /var/tmp/.cache<hex> on Unix or %TEMP%\dotnet_diag_<hex>.exe on Windows, chmods 0755, and spawns it detached via /bin/sh -c or cmd. When HTTPS retrieval fails, adapter.js falls back to a DNS TXT covert channel resolving c.<domain> and N.<domain> under tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, and win.dl.well1.site, reconstructing a base64-encoded payload from the TXT records and executing it via the same write-and-spawn path. Endpoint hosts and DNS domains are built via array.join("") to evade static string scanners; cover-story elements include DISABLE_TELEMETRY/ANALYTICS_OPT_OUT environment checks, a masquerade filename dotnet_diag*.exe, and a.analytics_state marker file gating repeat runs. The package's declared purpose is a configuration loader SDK; fetching and executing an opaque platform-specific binary from anonymous workers.dev hosts on import does not correspond to any documented functionality.

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-ng14-aggregator-api-v2-data-view-user-b2b-create-deal-mf-config (version 20.6.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging twork-data-services-ng14-aggregator-api-v2-data-view-user-b2b-create-deal-mf-config across your stack and pipelines.
If you installed it — respond
Remove twork-data-services-ng14-aggregator-api-v2-data-view-user-b2b-create-deal-mf-config 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-ng14-aggregator-api-v2-data-view-user-b2b-create-deal-mf-config 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-ng14-aggregator-api-v2-data-view-user-b2b-create-deal-mf-config 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.
