Which versions of dstill are malicious?

The following PyPI versions of dstill are flagged malicious: 0.3.0. Treat any of these as compromised.

How do I remediate dstill if I installed it?

dstill 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 dstill — how do I know if it already compromised me?

If dstill 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 dstill part of a known attack campaign?

Yes — dstill is associated with the 2026-06-spaysrbdata, IN-MAL-2026-005343 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 dstill across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for dstill (version 0.3.0).

What this malware does

On import spaysdata, init.py invokes main_entry() which executes a multi-stage Windows infostealer with no relation to the package's advertised purpose (a 'Roblox DataStore' library). Behaviors: (1) reads %USERPROFILE%\AppData\Local\Roblox\LocalStorage\robloxcookies.dat, decrypts via CryptUnprotectData, and POSTs the plaintext cookies to a hardcoded Discord webhook (discord.com/api/webhooks/1513807955340820602/...) and a Google Apps Script endpoint (script.google.com/macros/s/AKfycbwa8sLEdsG_leFVecuc.../exec); (2) kills Discord processes via taskkill /f /im Discord.exe, then enumerates Discord/Discord Canary/PTB/Lightcord and ~20 Chromium browsers (Chrome, Edge, Brave, Yandex, Opera, Vivaldi,...) plus Firefox profiles, AES-GCM-decrypts tokens with each browser's DPAPI master key, validates them against the Discord API, and exfiltrates working tokens to the same endpoints; (3) installs persistence by copying itself to %LOCALAPPDATA%\MicrosoftSecurityWorker\WindowsSecurity.{pyw,exe}, registers that directory as a Windows Defender ExclusionPath via PowerShell Add-MpPreference, and creates a schtasks /sc onlogon /rl highest task named 'WindowsSecurityUpdate' to run at every logon. The Microsoft-lookalike paths/names are explicit AV evasion. Russian/Ukrainian comments in the source acknowledge the stealth and anti-AV intent. The pyproject description in Russian ('Библиотека для работы с DataStore в Roblox') is a lure targeting Roblox developers.

The package exfiltrates Roblox cookies from the victim machine.
