twork-products-taiga2-products-investmentnpm
twork-products-taiga2-products-investment is a confirmed malicious npm package (MAL-2026-12305) that opens a backdoor for remote access (malicious version 20.2.8). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in twork-products-taiga2-products-investment (npm)
What this malware does
On require of the package, init.js (unconditionally loaded from index.js) fetches a platform-specific executable from one of three obfuscated Cloudflare Workers hosts (oob-worker.cf101-adf.workers.dev, cf102-baf.workers.dev, cf103-070.workers.dev), with a base64-over-DNS-TXT fallback via tin.dl.well1.site. The C2 hostnames are runtime-assembled from split string arrays to evade static inspection. The fetched binary is written to a disguised temp path (dotnet_diag<rand>.exe on Windows or.cache_<rand> on POSIX), chmod 0755, and spawned detached via /bin/sh -c '<path> &' or cmd.exe /c start /b, with a /tmp lock file gating re-execution. A second, currently-unreferenced dropper is also bundled at lib/telemetry.js under an 'analytics SDK' cover story, using string-concat require('child_'+'process') and the same fetch-write-chmod-spawn shape with a base64-chunked embedded buffer.
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
Backdoor / remote accessFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for twork-products-taiga2-products-investment (version 20.2.8). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging twork-products-taiga2-products-investment across your stack and pipelines.
If you installed it — respond
twork-products-taiga2-products-investment establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.
Did it already run?
If twork-products-taiga2-products-investment 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-products-taiga2-products-investment 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.
