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 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.

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.

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.
