Which versions of hex2pcap are malicious?

The following PyPI versions of hex2pcap are flagged malicious: 99.0.0. Treat any of these as compromised.

How do I remediate hex2pcap if I installed it?

hex2pcap 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 hex2pcap — how do I know if it already compromised me?

If hex2pcap was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is hex2pcap part of a known attack campaign?

Yes — hex2pcap is associated with the GENERIC-standard-pypi-install-pentest 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 hex2pcap across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for hex2pcap (version 99.0.0).

What this malware does

Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.

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-standard-pypi-install-pentest

Reasons (based on the campaign):

The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.
The package overrides the install command in setup.py to execute malicious code during installation.

The OpenSSF Package Analysis project identified 'hex2pcap' @ 99.0.0 (pypi) as malicious.

It is considered malicious because:

The package communicates with a domain associated with malicious activity.
