Which versions of py-2equests are malicious?

The following PyPI versions of py-2equests are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate py-2equests if I installed it?

py-2equests 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 py-2equests — how do I know if it already compromised me?

If py-2equests 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 py-2equests part of a known attack campaign?

Yes — py-2equests is associated with the 2026-09-0requests, IN-MAL-2026-019378 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 py-2equests across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for py-2equests (version 0.0.1).

What this malware does

py-2equests is a typosquat of the popular 'requests' package (substituting '2' for 'r'). On import py_2equests, the top-level module body iterates os.environ and collects all variables whose keys start with SECRET, API, TOKEN, or KEY, then opens a TCP socket to a host/port taken from the TS_HOST/TS_PORT environment variables (defaulting to 127.0.0.1:9999 but overridable to any remote destination) and sends the collected secrets over it. The same import path then spawns a python subprocess that connects back to the same TS_HOST:TS_PORT, sends the literal 'SHELL', and holds the socket open as a reverse-shell channel, described in an author comment as a 'reverse shell hook'. A code comment reads 'Exfiltrate env vars and open reverse shell on install' and the CLI prints 'py_2equests installed -- targeting requests', self-documenting the intent. Any process that imports the package leaks credential-shaped environment variables and grants remote shell access to whoever controls the configured destination.

During import, the code exfiltrates potentially sensitive env variables. In all analyzed versions the exfiltration target was a localhost, suggesting it was just a test.

Detect & block this

O3 blocks py-2equests-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
