Which versions of cryptowallethash are malicious?

The following PyPI versions of cryptowallethash are flagged malicious: 0.0.6, 0.0.7, 0.0.8. Treat any of these as compromised.

How do I remediate cryptowallethash if I installed it?

cryptowallethash 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 cryptowallethash — how do I know if it already compromised me?

If cryptowallethash 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 cryptowallethash part of a known attack campaign?

Yes — cryptowallethash is associated with the 2026-02-old-cryptowallethash 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 cryptowallethash 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 cryptowallethash (3 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging cryptowallethash across your stack and pipelines.

MAL-2026-846

Immediate action

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

pip uninstall cryptowallethash

What this malware does

The package claims to calculate a hash value for usage in "cryptocurrency", but before returning the hash, it exfiltrates the plain value.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Credential / info stealer

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for cryptowallethash (3 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging cryptowallethash across your stack and pipelines.
If you installed it — respond
cryptowallethash 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.
Did it already run?
If cryptowallethash 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 cryptowallethash 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

No. cryptowallethash on PyPI has been identified as a malicious package (versions 0.0.6, 0.0.7, 0.0.8 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks cryptowallethash-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
