inversiones-commonPyPI
Advisory published Updated
inversiones-common is a confirmed malicious PyPI package (MAL-2026-6262) that steals credentials and exfiltrates sensitive data (malicious versions 99.0.0, 99.0.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in inversiones-common (PyPI)
What this malware does
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.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for inversiones-common (2 malicious versions).
If you installed it — respond
inversiones-common 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 inversiones-common 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.

Detect & block this
O3 blocks inversiones-common-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
