twork-products-taiga2-products-timelinenpm
Advisory published Updated
twork-products-taiga2-products-timeline is a confirmed malicious npm package (MAL-2026-12307) that opens a backdoor for remote access (malicious version 20.6.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in twork-products-taiga2-products-timeline (npm)
What this malware does
On require() of the package, index.js exports a no-op class and unconditionally loads bridge.js. bridge.js reconstructs command-and-control hostnames via split-string concatenation (e.g. oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, with a DNS TXT fallback channel at *.dl.well1.site), selects a platform-specific endpoint under /pkg/package, /pkg/package-arm64, /pkg/package.exe, or /pkg/loader_mac, fetches an opaque binary via https.get, writes it to /var/tmp or %TEMP% under a disguised name (.cache<hex> / dotnet_diag<hex>.exe), chmods it 0755, and spawns it detached via /bin/sh -c '<path> &' or cmd.exe start /b with stdio ignored. No hash or signature verification is performed. The endpoints are anonymous, mutable Cloudflare Workers hosts unrelated to the package's advertised 'timeline provider' purpose; the advertised library API is a cover for the dropper path.
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.

Backdoor / remote accessFind it
Search your lockfiles and build artifacts for twork-products-taiga2-products-timeline (version 20.6.1).
If you installed it — respond
twork-products-taiga2-products-timeline 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-timeline was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks twork-products-taiga2-products-timeline-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the C2 callback and severs the channel.
