Which versions of hhonestjson are malicious?

The following PyPI versions of hhonestjson are flagged malicious: 0.1.3. Treat any of these as compromised.

How do I remediate hhonestjson if I installed it?

Remove hhonestjson 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 hhonestjson — how do I know if it already compromised me?

If hhonestjson 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 hhonestjson part of a known attack campaign?

Yes — hhonestjson is associated with the GENERIC-simple-tests 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 hhonestjson 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 hhonestjson (version 0.1.3). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging hhonestjson across your stack and pipelines.

MAL-2024-12286

Immediate action

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

pip uninstall hhonestjson

What this malware does

Packages that might be part of testing for pentesting / malicious activity / joy, with suspicious activity that does not present any real harm.

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: GENERIC-simple-tests

Reasons (based on the campaign):

The package overrides the install command in setup.py to execute malicious code during installation.

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 hhonestjson (version 0.1.3). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging hhonestjson across your stack and pipelines.
If you installed it — respond
Remove hhonestjson 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 hhonestjson 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 hhonestjson 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

Detect & block this

O3 blocks hhonestjson-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
