pflag29424npm
pflag29424 is a confirmed malicious npm package (MAL-2026-16342) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in pflag29424 (npm)
What this malware does
index.js (the package's declared main) unconditionally executes on module load: it calls fetch('/profile'), scans the response for a DGA{...} token, and sends either the matched token or the first 300 characters of the response as a query parameter to a hardcoded anonymous collector at https://webhook.site/42c6d937-77c7-42a5-8678-ef06b4501e38. The package has no README, no documented purpose, and a generic throwaway name; the sole effect of loading it is to relay content from the loading context to an attacker-controlled webhook.site endpoint.

Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for pflag29424 (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging pflag29424 across your stack and pipelines.
If you installed it — respond
pflag29424 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 pflag29424 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 pflag29424 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.
