Advisory published Updated
statist-browser-typed-client-eventea.projects.pfpacquiring is a confirmed malicious npm package (MAL-2026-12445) that typosquats a legitimate package to trick installs (malicious version 20.5.8). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in statist-browser-typed-client-eventea.projects.pfpacquiring (npm)
What this malware does
index.js unconditionally require()s bridge.js, which on load detects OS and architecture, assembles destination hostnames via array-join string concatenation to hide them from static scanners (oob-worker.cf101-*.workers.dev variants, with DNS TXT-record fallback resolution against tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site), downloads a platform-specific binary via https.get, writes it to /tmp or the Windows TEMP directory under names mimicking OS internals (dotnet_diag<hex>.exe,.cache_<hex>), fs.chmodSync 0755, and spawns it detached via /bin/sh -c "<path> &" or cmd.exe /c start. A sibling file lib/telemetry.js (not reachable from the main entry) contains matching dropper primitives — base64 chunk assembly, cp.spawn("/bin/sh",...), fs["chmod"+"Sync"] with parseInt("755",8) — under an analytics-SDK cover story, indicating a staged variant. The require() chain fires as a side effect of importing the package, so any consumer that installs and loads it executes attacker-controlled binaries on the host.
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.

TyposquatFind it
Search your lockfiles and build artifacts for statist-browser-typed-client-eventea.projects.pfpacquiring (version 20.5.8).
If you installed it — respond
statist-browser-typed-client-eventea.projects.pfpacquiring is a typosquat — you almost certainly intended a legitimately-named package. Remove statist-browser-typed-client-eventea.projects.pfpacquiring, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If statist-browser-typed-client-eventea.projects.pfpacquiring 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 statist-browser-typed-client-eventea.projects.pfpacquiring-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
