Malicious code in dolyame-boxy-mobile-bnpl-text-block (npm)
What this malware does
On any require() of the package, index.js loads./compat.js, which fetches a native binary from string-fragmented Cloudflare Workers hosts under oob-worker.cf*.workers.dev (with a DNS TXT-record fallback that reassembles base64 chunks from subdomains under sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru), writes the payload to /var/tmp or %TEMP% under a disguised name (dotnet_diag<hex>.exe on Windows,.cache_<hex> on Unix), chmods it 0755, and spawns it detached via /bin/sh -c or cmd /c start. Network destinations are hidden by array-joining fragmented substrings and require() is invoked as require('child_'+'process') to evade static matching. No integrity check, no consent prompt, and only an environment-variable opt-out. A dormant secondary dropper in lib/telemetry.js ships in the tarball with the same spawn/chmod/base64 shape framed as an analytics SDK, but is not reached from index.js in this version.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for dolyame-boxy-mobile-bnpl-text-block (version 35.1.8).
If you installed it — respond
Remove dolyame-boxy-mobile-bnpl-text-block 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-boxy-mobile-bnpl-text-block 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-boxy-mobile-bnpl-text-block-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.
