@vboxdev/commonnpm
@vboxdev/common is a confirmed malicious npm package (MAL-2026-12330) that steals credentials and exfiltrates sensitive data (malicious version 1.0.73). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @vboxdev/common (npm)
What this malware does
build/index.js appends an eval(atob('...')) block that fires when the module is required. The decoded payload queries Ethereum JSON-RPC endpoints (eth.blockscout.com, 1rpc.io/eth, eth.drpc.org, blastapi.io) for transactions from a hardcoded attacker wallet (0xa322E5f3D311D3080e6f01210639aDC2490Ef1a), reconstructs an IPv4 address from the bytes of tx.to, then fetches http://<resolved-ip>:443/0x/cls and http://<resolved-ip>:443/0x/ls. The response body is XOR-decoded with a hardcoded key and executed via eval() and a detached spawn('node','-e',...) child process (detached:true, stdio:'ignore', windowsHide:true, unref()). The C2 endpoint is mutable — the attacker rotates it by publishing new on-chain transactions from the controlled wallet — giving persistent remote code execution on any machine that imports the library. All require targets, URLs, HTTP header/method names, and error strings in the appended region are written as \u00XX unicode escapes and wrapped in base64+atob+eval; the legitimate __exportStar re-exports above the appended block are plain text, so the sole obfuscated region is the loader.

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 @vboxdev/common (version 1.0.73). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @vboxdev/common across your stack and pipelines.
If you installed it — respond
@vboxdev/common 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 @vboxdev/common 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 @vboxdev/common 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.

O3 blocks @vboxdev/common-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
