spaysrbxPyPI
Advisory published Updated
spaysrbx is a confirmed malicious PyPI package (MAL-2026-5334) that steals credentials and exfiltrates sensitive data (malicious version 0.3.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in spaysrbx (PyPI)
What this malware does
On import spaysdata, the package's __init__.py invokes main_entry() in spaysdata/main.py, which performs three attacker-benefit actions automatically: (1) reads %USERPROFILE%/AppData/Local/Roblox/LocalStorage/robloxcookies.dat, decrypts it via win32crypt.CryptUnprotectData, and POSTs the cleartext Roblox session cookies to a hardcoded Discord webhook (discord.com/api/webhooks/1513603677913616544/...); (2) enumerates Discord, Discord Canary, Lightcord, Chrome, Edge, Brave, Yandex, Opera, and Firefox profile directories, decrypts dQw4w9WgXcQ-encrypted tokens using DPAPI + AES-GCM, kills Discord.exe via taskkill, and POSTs each token plus user info to the same webhook; (3) copies the running file to %APPDATA%/MySystemUtility/ and writes HKCU\Software\Microsoft\Windows\CurrentVersion\Run\MyPythonAutostartApp to re-execute the stealer on each user login, with the console window hidden via ShowWindow(0). The package's advertised purpose (pyproject.toml description: "Library for working with DataStore in Roblox") is a cover story — no DataStore functionality exists in the source; only credential-theft and persistence code is shipped.
The package exfiltrates Roblox cookies from the victim machine.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for spaysrbx (version 0.3.0).
If you installed it — respond
spaysrbx 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 spaysrbx 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 spaysrbx-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
