# MAL-2026-6262: Malicious code in inversiones-common (PyPI)


- **Type:** Malicious package
- **Package:** `inversiones-common` (PyPI)
- **Published:** 22 Jun 2026

## What is MAL-2026-6262?

MAL-2026-6262 is a malicious package in inversiones-common, published on 22 Jun 2026. 

### Official description

setup.py executes a `_beacon()` function at module top level (before `setup()` is called), so the payload fires automatically on `pip install inversiones-common`. The beacon collects: hostname, `id`/`uname` output, environment variables (including PIP_INDEX_URL, OKTA_TOKEN, AWS_*, GITHUB_*, and proxy credentials), `/etc/resolv.conf`, `/etc/hosts`, `/etc/machine-id`, pip configuration files (`~/.config/pip/pip.conf`, `/etc/pip.conf`, `~/.pip/pip.conf`) which commonly contain private-index basic-auth credentials, `pip list` output, network interface details, and probes the AWS IMDSv1 endpoint at `http://169.254.169.254/latest/meta-data/iam/security-credentials/` along with GCP and Azure metadata services to harvest cloud instance role credentials. The collected JSON blob is POSTed over plain HTTP to a hardcoded bare IP `http://157.173.126.113:8888/depconf-rce-v2`. The package name `inversiones-common` and version `99.0.1` (an artificially high version chosen to outrank private-index resolutions) target Fintual's internal namespace; the payload includes a `FINTUAL-DEPCONF-RCE-V2` marker and probes `gitea.fintual.in`. Self-described 'authorized bug bounty' framing in the source does not limit blast radius — anyone whose pip resolver picks up this public package, by typo or namespace confusion, will run the beacon and leak secrets to the attacker IP.

Generic campaign for all (likely) research / pentests, where the amount or art of collected data raises questions about the privacy, security and ethical side.

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

Campaign: GENERIC-questionable-pentest

Reasons (based on the campaign):

 - exfiltration-env-variables

 - exfiltration-generic

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

 - typosquatting

The OpenSSF Package Analysis project identified 'inversiones-common' @ 99.0.1 (pypi) as malicious.

It is considered malicious because:

- The package executes one or more commands associated with malicious behavior.

## What should I do about MAL-2026-6262?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
