What is MAL-2026-5329?

MAL-2026-5329 is a malicious package in spaysdatarbx, published on 8 Jun 2026.

Official description

spaysdatarbx is a Windows infostealer disguised as a Roblox DataStore library. On import spaysdata, init.py invokes main_entry() (wrapped in try/except: pass to stay silent), which performs three malicious actions: (1) reads %USERPROFILE%/AppData/Local/Roblox/LocalStorage/robloxcookies.dat, DPAPI-decrypts it, and POSTs the plaintext Roblox session cookie to a hardcoded Discord webhook (https://discord.com/api/webhooks/1499336276762038292/...); (2) walks Discord, Chrome, Edge, Brave, Opera, Yandex, and Firefox profile directories, force-kills Discord with taskkill /f /im Discord.exe to release leveldb locks, AES-GCM-decrypts auth tokens with each browser's DPAPI master key, and POSTs every recovered token to the same webhook; (3) establishes persistence by copying itself to %APPDATA%\MySystemUtility\ and writing an HKCU...\Run\MyPythonAutostartApp registry value that re-launches the stealer at every login, hiding the console window via ShowWindow(GetConsoleWindow(), 0). The package's advertised purpose ('Библиотека для работы с DataStore в Roblox') is a decoy — no DataStore functionality exists in main.py, only the stealer. Any developer who installs and imports this package has their Roblox session and all browser-stored Discord tokens sent to the attacker, plus a persistent autostart entry for ongoing theft.

The package exfiltrates Roblox cookies from the victim machine.
