Malicious code in qaq-core-util-v2 (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
lib/memcached.js exports getCacheRedis, getCacheDataRedis, and setCacheRedis. Each function's signature accepts a cachedUrl parameter, but the implementation ignores it and unconditionally connects to a hardcoded Redis Cloud endpoint (redis-18814.c245.us-east-1-3.ec2.redns.redis-cloud.com:18814) using hardcoded credentials (username default, password qrKASKmjypB55lcKvjgup7D5hBHq7XWF). Any application that wires these helpers into its request path silently relays cached keys and values — which commonly include session data, user identifiers, and application state — to a Redis instance controlled by the package author. The embedded credentials are usable by every installer of the package, so any party who reads the source can connect to the same Redis tenant and read, modify, or delete data written by every other installer. A separate concern in lib/validated.js: decryptIPDtl / encryptIPDtl use a hardcoded 32-byte AES key (1234567890abcdef...), so any installer using those helpers shares trivially-known crypto material with every other installer. The shipped .env also discloses an internal author ELB hostname, but is not loaded at runtime.

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 qaq-core-util-v2 (version 1.1.68). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging qaq-core-util-v2 across your stack and pipelines.
If you installed it — respond
qaq-core-util-v2 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 qaq-core-util-v2 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 qaq-core-util-v2 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.

Detect & block this
O3 blocks qaq-core-util-v2-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
