Which versions of @nasddatax/common are malicious?

The following npm versions of @nasddatax/common are flagged malicious: 1.0.21. Treat any of these as compromised.

How do I remediate @nasddatax/common if I installed it?

@nasddatax/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.

I already installed @nasddatax/common — how do I know if it already compromised me?

If @nasddatax/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.

Is @nasddatax/common part of a known attack campaign?

Yes — @nasddatax/common is associated with the IN-MAL-2026-014701, GHSA-mx45-4vrr-4fgp campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find @nasddatax/common across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @nasddatax/common (version 1.0.21). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @nasddatax/common across your stack and pipelines.

Malicious package

@nasddatax/commonnpm

@nasddatax/common is a confirmed malicious npm package (MAL-2026-12323) that opens a backdoor for remote access (malicious version 1.0.21). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall @nasddatax/common

What this malware does

build/index.js appends an eval(atob(...)) trailer after legitimate re-exports. On require, the decoded loader queries public Ethereum JSON-RPC endpoints for the latest transaction from the hardcoded address 0xa322E5f3D311D3080e6f0121063e9aDC2490Ef1a, decodes the 20-byte tx.to value into two IPv4 addresses, fetches an XOR-obfuscated JavaScript payload from http://<ip>:443/0x/cls and http://<ip>:443/0x/ls, decodes an x-payload-b64 response header, and executes the result via eval and a detached spawn('node', ['-e', payload]). Security-relevant identifiers (http, child_process, spawn, method and header strings) are written as \u00XX unicode escapes to hide the behavior. Any application that requires this package runs attacker-controlled code on the installer's machine, and the C2 destination can be rotated on-chain without republishing the package. Package metadata (empty author, empty description, scoped <scope>/common name) is consistent with an impostor common-utilities package.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Detection & response playbook

Backdoor / remote access

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @nasddatax/common (version 1.0.21). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @nasddatax/common across your stack and pipelines.
If you installed it — respond
@nasddatax/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 @nasddatax/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 @nasddatax/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.

Frequently asked questions
