strapi-plugin-weccresh-meebnpm
strapi-plugin-weccresh-meeb is a confirmed malicious npm package (MAL-2026-16192) that steals credentials and exfiltrates sensitive data (malicious version 3.6.8). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in strapi-plugin-weccresh-meeb (npm)
What this malware does
The package's postinstall.js (also declared as main) executes automatically on npm install and performs bulk host reconnaissance and credential theft against the installer. It captures os.hostname() and os.userInfo(), serializes the full process.env, reads Strapi configuration under /app/config/* and /app/.env*, recursively walks the filesystem from '/' to collect files matching.env* and private-key/certificate patterns (pem, key, crt, cert, p12, pfx, jks, id_rsa, wallet), reads Kubernetes service-account tokens under /var/run/secrets/kubernetes.io/serviceaccount/token and /run/secrets, probes /var/run/docker.sock, reads /etc/hosts and /etc/resolv.conf, and queries Redis INFO/DBSIZE and database table counts via knex. The collected data is gzip-compressed, base64-encoded, split into 3500-byte chunks, and POSTed with staggered timeouts to the hardcoded Burp Collaborator host q0r2hkrfha7y7zhz6nxtqqifv61xppde.oastify.com on port 80. The package name mimics a Strapi plugin but ships no plugin code; the postinstall exfiltration is the only behavior.

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 strapi-plugin-weccresh-meeb (version 3.6.8). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging strapi-plugin-weccresh-meeb across your stack and pipelines.
If you installed it — respond
strapi-plugin-weccresh-meeb 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 strapi-plugin-weccresh-meeb 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 strapi-plugin-weccresh-meeb 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.
