Which versions of chia-pool-reference are malicious?

The following PyPI versions of chia-pool-reference are flagged malicious: 9.0.1, 9.1.0. Treat any of these as compromised.

How do I remediate chia-pool-reference if I installed it?

chia-pool-reference 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.

I already installed chia-pool-reference — how do I know if it already compromised me?

If chia-pool-reference 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 chia-pool-reference part of a known attack campaign?

Yes — chia-pool-reference is associated with the 2026-02-zabitmajeed00, RLMA-2026-00189 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 chia-pool-reference 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 chia-pool-reference (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging chia-pool-reference across your stack and pipelines.

What this malware does

Obfuscated code is used to hide exfiltration of basic data (hostname, etc.).

Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.

Campaign: 2026-02-zabitmajeed00

Reasons (based on the campaign):

obfuscation
The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for chia-pool-reference (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging chia-pool-reference across your stack and pipelines.

Did it already run?
If chia-pool-reference 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 chia-pool-reference 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.
