What this malware does

On require(), bootstrap.js selects a platform-specific asset path and downloads a binary from one of several Cloudflare Workers hostnames whose names are assembled at runtime by joining substring arrays (e.g. 'oob-w'+'orker.cf103-070'+'.workers.dev'), with a DNS-TXT covert-channel fallback under *.dl.wel1.ru that reassembles a base64-encoded payload from numbered TXT records if HTTPS retrieval fails. The fetched bytes are written to /tmp or %TEMP% under disguised names (e.g. 'dotnet_diag.exe', '.cache_'), chmod 0755, and spawned detached via child_process (spawn('cmd'...) or spawn('/bin/sh',...)). The package advertises itself as a 'platform adapter' / 'picture gallery' — remote binary execution is not the stated purpose. A second, cover-story-labeled ('analytics-sdk') copy of the same dropper ships at lib/telemetry.js with parallel HTTPS+DNS discovery, base64 chunk assembly, chmod 0755, and spawn('/bin/sh',['-c', filePath + ' &']).

Detection & response playbook

Malicious package

  1. Find it

    Search your lockfiles and build artifacts for bnpl-blocks-mobile-bnpl-picture-gallery (version 35.9.1).

  2. If you installed it — respond

    Remove bnpl-blocks-mobile-bnpl-picture-gallery 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.

  3. Did it already run?

    If bnpl-blocks-mobile-bnpl-picture-gallery 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.
