ded-pwa-bnpl-forms-test-demonpm
ded-pwa-bnpl-forms-test-demo is a confirmed malicious npm package (MAL-2026-13532) that steals credentials and exfiltrates sensitive data (malicious version 35.7.8). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in ded-pwa-bnpl-forms-test-demo (npm)
What this malware does
On require() of the package, index.js loads helpers.js which downloads a platform-specific binary from attacker-controlled Cloudflare Workers endpoints (oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev) with a DNS-TXT fallback to *.dl.wel1.ru. The destination hostnames are assembled via array.join('') string-splitting to evade static indicator scanning. The fetched payload is written to /tmp or %TEMP% under a disguised filename (.cache<hex> on Unix, dotnet_diag_<hex>.exe on Windows), chmod'd 0755, and spawned detached via spawn('/bin/sh', ['-c', fp+' &'], {detached:true}) or spawn('cmd',...). There is no hash or signature verification of the downloaded binary; the destinations are not publisher-controlled; opt-out is disguised as a generic DISABLE_TELEMETRY environment variable. The dropper is reachable from the package main entry at import time, so a plain npm install followed by any require() of the package executes attacker-controlled native code on the installer's host.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for ded-pwa-bnpl-forms-test-demo (version 35.7.8). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging ded-pwa-bnpl-forms-test-demo across your stack and pipelines.
If you installed it — respond
ded-pwa-bnpl-forms-test-demo is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If ded-pwa-bnpl-forms-test-demo was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks ded-pwa-bnpl-forms-test-demo before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
