@nasdtickets/commonnpm
@nasdtickets/common is a confirmed malicious npm package (MAL-2026-12324) that opens a backdoor for remote access (malicious version 1.0.23). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @nasdtickets/common (npm)
What this malware does
build/index.js (the package main) appends a hidden eval(atob('...')) block after the legitimate __exportStar boilerplate, separated by a long run of tab characters to push it off-screen in editors. On every require/import of the package, the decoded payload queries an Ethereum RPC/Blockscout endpoint for the latest transaction of the hardcoded EOA 0xa322E5f3D311D3080e6f0121063e9aDC2490Ef1a, interprets the 20-byte tx.to address as two encoded IPv4 addresses, and issues HTTP requests to http://<resolved-ip>:443/0x/cls and http://<resolved-ip>:443/0x/ls. The response carries a payload in the x-payload-b64 header that is XOR-decoded and then executed via spawn('node', ['-e', <decoded>], {detached: true, stdio: 'ignore', windowsHide: true}).unref(), launching a detached hidden Node process on the installer's machine. Module identifiers such as 'http', 'https', 'child_process', and 'spawn' are unicode-escaped (\u00XX) to further hide the behavior. The combination of on-chain C2 resolution (resistant to DNS/domain takedown), multi-layer obfuscation, and hidden detached process execution on import is a remote-code-execution supply-chain attack against any project that installs this version.

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 @nasdtickets/common (version 1.0.23). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @nasdtickets/common across your stack and pipelines.
If you installed it — respond
@nasdtickets/common 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 @nasdtickets/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 @nasdtickets/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.
