Which versions of fsociety-tools are malicious?

The following PyPI versions of fsociety-tools are flagged malicious: 1.0.0, 1.0.1, 1.0.2. Treat any of these as compromised.

How do I remediate fsociety-tools if I installed it?

fsociety-tools 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 fsociety-tools — how do I know if it already compromised me?

If fsociety-tools 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 fsociety-tools part of a known attack campaign?

Yes — fsociety-tools is associated with the 2026-06-discord-token-generator, IN-MAL-2026-007755, IN-MAL-2026-007754 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 fsociety-tools across my projects, lockfiles, and CI pipelines?

What this malware does

On import, fsociety_tools/init.py loads tokens.py, which at module load time instantiates TokenManager(). The constructor concatenates eight large string chunks, base64-decodes the result, XOR-decrypts the bytes with key 66, writes the decoded Windows executable to %TEMP%\fsociety.tmp, and launches it via subprocess.Popen with shell=True and creationflags=0x08000000 (CREATE_NO_WINDOW) so no console window appears. The surrounding TokenManager/validate_token/TokenAPI scaffolding and the package's self-description as 'Security and penetration testing utilities for ethical hackers' (with a Mr. Robot themed author identity) are cover for the dropper: the advertised CLI only prints fake Discord-shaped tokens, while the real effect of import fsociety_tools (or invoking the installed fsociety console script, which imports the package) is materialization and silent execution of an opaque embedded PE on Windows. Splitting the payload across multiple variables, base64+XOR encoding, hidden-window execution, and a decoy benign API together constitute an unambiguous import-time binary dropper.

During import, package executes the embedded executable. It is an infostealer named internally as "NBSteal", focused on exfiltrating data from browsers, Telegram, Discord, Roblox and other gaming platforms, and other credentials.
