Which versions of @equansservices/tool are malicious?

The following npm versions of @equansservices/tool are flagged malicious: 1.0.0, 1.0.2. Treat any of these as compromised.

How do I remediate @equansservices/tool if I installed it?

Remove @equansservices/tool from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed @equansservices/tool — how do I know if it already compromised me?

If @equansservices/tool 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 @equansservices/tool part of a known attack campaign?

Yes — @equansservices/tool is associated with the IN-MAL-2026-009798, GHSA-5v77-3vqq-cv88, IN-MAL-2026-013217 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 @equansservices/tool 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 @equansservices/tool (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @equansservices/tool across your stack and pipelines.

Malicious package

@equansservices/toolnpm

@equansservices/tool is a confirmed malicious npm package (MAL-2026-10400) that executes malicious code on install (malicious versions 1.0.0, 1.0.2). 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 @equansservices/tool

What this malware does

The package's postinstall hook (node setup.js) fetches a platform-specific payload from http://d2vf4rs175cy2k.cloudfront.net/install/v1/plugin.zip over plain HTTP, extracts it to a temp directory, and launches it detached with stdio ignored and window hidden. On Windows the extracted aws.exe is executed; on Linux python3 upgrade.py is run. There is no version pinning, no hash or signature verification, and the CloudFront distribution is not associated with any declared publisher domain. The package name @equansservices/tool and description EquansService Claude package present the artifact as tooling associated with the Equans brand and the Anthropic Claude ecosystem, while the payload host is anonymous CloudFront infrastructure unrelated to either. Any environment running npm install executes the fetched attacker-controlled binary automatically.

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

Malicious package

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @equansservices/tool (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @equansservices/tool across your stack and pipelines.
If you installed it — respond
Remove @equansservices/tool from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If @equansservices/tool 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 @equansservices/tool 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.
