Advisory published Updated

Malicious code in dolyame-ui-pagination (npm)
What this malware does
On require of the package, index.js loads./polyfill.js, which immediately executes a dropper routine. The dropper assembles destination hostnames at runtime via array-join string splitting to evade static matching, resolving to Cloudflare Workers endpoints (oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev). A platform-specific binary is downloaded, written to /tmp or %TEMP% under disguised names such as.cache<hex> or dotnet_diag_<hex>.exe, chmod'd to 0755, and spawned detached via /bin/sh -c or cmd. A secondary covert channel resolves TXT records under sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru, base64-decoding the concatenated TXT fragments into an executable buffer when the HTTPS mirrors fail. A sibling module lib/telemetry.js ships the same dropper primitives (base64-decoded buffer, split-property fs['chmod'+'Sync'], /bin/sh spawn) though it is not on the entrypoint graph from index.js. Destinations are unrelated to the package's stated purpose (a UI pagination component), unpinned, and unverified; the fetched bytes are opaque and executed.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for dolyame-ui-pagination (version 35.2.5).
If you installed it — respond
Remove dolyame-ui-pagination 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 dolyame-ui-pagination 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 dolyame-ui-pagination-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.
