devplatform-nx-glenpm
Advisory published Updated
devplatform-nx-gle is a confirmed malicious npm package (MAL-2026-12723) that executes malicious code on install (malicious version 35.5.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in devplatform-nx-gle (npm)
What this malware does
On require() of devplatform-nx-gle, index.js side-loads a sibling module bridge.js inside a swallowing try/catch. bridge.js reconstructs hardcoded Cloudflare Workers hostnames from split string fragments joined at runtime (oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev), downloads a platform-specific native executable via https.get, writes it under /tmp or %TEMP% with decoy filenames such as dotnet_diag<rand>.exe or.cache<rand>, chmods it 0755, and spawns it detached via spawn("/bin/sh", ["-c",...]) or spawn("cmd",...). A DNS TXT-record channel over sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru serves as a fallback delivery path. The advertised package purpose is a trivial no-op class described as a shared backend integration library; the dropper module is unrelated to that advertised API. Hostnames are constructed via string-join concatenation to defeat static string matching, and the try/catch around the _bridge require() silently suppresses failures.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for devplatform-nx-gle (version 35.5.3).
If you installed it — respond
Remove devplatform-nx-gle 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 devplatform-nx-gle 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 devplatform-nx-gle-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.
