Malicious package

bytekafka-0-0-15PyPI

Advisory published Updated

bytekafka-0-0-15 is a confirmed malicious PyPI package (MAL-2024-10356) that steals credentials and exfiltrates sensitive data (malicious versions 98.7, 99.7). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in bytekafka-0-0-15 (PyPI)

MAL-2024-10356
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall bytekafka-0-0-15

What this malware does

A campaign of probably pentest packages flooding PYPI. Installing the package or importing the module triggers reporting basic info like hostname, path and the username to the package author. There is no other purpose of the package.

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: 2024-11-byted-dast

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.

  • typosquatting

  • dependency-confusion

The OpenSSF Package Analysis project identified 'bytekafka-0-0-15' @ 99.7 (pypi) as malicious.

It is considered malicious because:

  • The package communicates with a domain associated with malicious activity.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for bytekafka-0-0-15 (2 malicious versions).

  2. If you installed it — respond

    bytekafka-0-0-15 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.

  3. Did it already run?

    If bytekafka-0-0-15 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.

Frequently asked questions

No. bytekafka-0-0-15 on PyPI has been identified as a malicious package (versions 98.7, 99.7 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks bytekafka-0-0-15-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
