What does the dolyame-ui-inputpassword malware do?

On require of the package, index.js loads lib/telemetry.js which, together with _bootstrap.js, fetches a platform-specific binary from a rotating list of anonymous Cloudflare Workers hosts (oob-worker.cf1{00,01,02,03}-*.workers.dev) with a DNS-TXT covert-channel fallback under sdk.dl.wel1.ru (chunk count from c. , base64 chunks from indexed TXT records reassembled via Buffer.from(..., 'base64')). The fetched bytes are written to a disguised temp path (.cache_ /dotnet_diag_ .exe), chmodded to 0755, and spawned detached via /bin/sh -c or cmd.exe /c start. Destination hostnames and module names are assembled from split string fragments (e.g. 'oob-worker.cf103-070.wo'+'rkers.d'+'e

Which versions of dolyame-ui-inputpassword are malicious?

The following npm versions of dolyame-ui-inputpassword are flagged malicious: 35.8.1. Treat any of these as compromised.

How do I remediate dolyame-ui-inputpassword if I installed it?

Remove dolyame-ui-inputpassword 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.

I already installed dolyame-ui-inputpassword — how do I know if it already compromised me?

If dolyame-ui-inputpassword 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.

Is dolyame-ui-inputpassword part of a known attack campaign?

Yes — dolyame-ui-inputpassword is associated with the IN-MAL-2026-016894 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find dolyame-ui-inputpassword across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for dolyame-ui-inputpassword (version 35.8.1).

What this malware does

On require of the package, index.js loads lib/telemetry.js which, together with bootstrap.js, fetches a platform-specific binary from a rotating list of anonymous Cloudflare Workers hosts (oob-worker.cf1{00,01,02,03}-*.workers.dev) with a DNS-TXT covert-channel fallback under sdk.dl.wel1.ru (chunk count from c.<domain>, base64 chunks from indexed TXT records reassembled via Buffer.from(..., 'base64')). The fetched bytes are written to a disguised temp path (.cache<hex>/dotnet_diag_<hex>.exe), chmodded to 0755, and spawned detached via /bin/sh -c or cmd.exe /c start. Destination hostnames and module names are assembled from split string fragments (e.g. 'oob-worker.cf103-070.wo'+'rkers.d'+'ev', require('child_'+'process'), fs['chmod'+'Sync']) to evade static string search. The package presents itself as a UI input-password wrapper; the dropper behavior is unrelated to that stated purpose and is duplicated across _bootstrap.js and lib/telemetry.js so it fires whether the package is loaded via the main entry or the bootstrap side-effect.
