ABOUT Penguin Domination 🐧

Spyware in games? No thanks!

This group focuses on the technical examination of software behavior in games and related platforms. Evaluations include the use of telemetry, analytics services, cloud storage systems, always-online requirements, and third-party integrations. Particular attention is paid to how data is collected, stored, processed, transmitted and how this affects functionality in offline or restricted network environments.

The reviews refer to established transparency and data protection standards, including the GDPR. All findings are based on observable network activity, client-side behavior, documented infrastructure components and publicly available technical evidence.

Review Criteria and Corrections
No assessments are made regarding entertainment value, gameplay experience or personal preference. The focus is on verifiable technical characteristics and their practical implications for users and developers.

Developers may provide technical documentation or clarification. Verified corrections and transparent implementation details are incorporated into the database and review summaries.

What does the group provide?
  1. Technical analyses of data collection, telemetry, cloud systems, and network dependencies in games and clients.
  2. Documentation of third-party service integrations and data processing workflows.
  3. Guides and reference materials for configuring privacy tools, network controls, and host-based filtering.
  4. Discussion of transparency standards, data protection regulations, and industry practices.
  5. Resources to support informed decisions regarding software behavior and data flows.

[EN|DE] Steam Client: Network Changes / Netzwerkänderungen
Original Analysis
https://steamcommunity.com/sharedfiles/filedetails/?id=3608562371
After the latest update of the Steam client, an analysis of the network connections shows that a huge part of the infrastructure is now routed through various Google services. Newly appearing in the active connections are components such as Google Optimization, Google Safe Browsing, Google Account and Google Autofill.

Summary of Services
IP Addresses
IPv4: 108
IPv6: 8

Domains
Akamai Technologies: 12
Steamcontent: 8
Google 1e100.net: 77
Valve: 2
FastlyCDN: 2

Google Services
accounts.google.com
content-autofill.googleapis.com
www.google.com
safebrowsing.googleapis.com
optimizationguide-pa.googleapis.com

Functional Description
The requests appear to load technical models and security data. The Google account check verifies whether an account is stored in the local profile without transmitting account information. The Autofill services load model configurations used for detecting form fields. The Optimization Guide retrieves model information for performance and interface optimizations. Safe Browsing updates the local threat lists.

Transmitted Data
IP address, timestamp, TLS data, user agent, accept-language, accept-encoding, origin, host, connection, content-type, content-length, gpsia, source, json, X-Client-Data, key/API key, protobuf payload, X-Goog-Encode-Response-If-Executable, X-Goog-Api-Key, sec-fetch-site, sec-fetch-mode, sec-fetch-dest, request URL, query parameters, X-HTTP-Method-Override, Safe Browsing list IDs, Safe Browsing version states, Safe Browsing hash-range information, Safe Browsing delta-update requests.

Additional Google Infrastructure
steamcloud-ugc.storage.googleapis.com
redirector.gvt1.com
r4---sn-4g5ednks.gvt1.com

"UGC" stands for "User-Generated Content", meaning content uploaded by users is stored in Google Cloud.

The *.gvt domains also belong to Google's infrastructure. They distribute various types of content such as update packages, extensions, media files and advertising videos across multiple platforms.

Chrome Settings in Steam Client
Some settings can be changed/adjusted/disabled in Steam, for example, under

chrome://flags/ for experimental settings such as WebRTC leaks, overlays
chrome://settings/ for privacy settings, cookies
chrome://history/ your browser history in Steam
chrome://device-log/ Log of all connected or disconnected devices

Unfortunately, not the basic behavior...

Edit 1: Valve Statement - November 20, 2025
https://steamcommunity.com/sharedfiles/filedetails/?id=3609251822
A Valve employee has commented on lightwo's thread. The behavior is being reviewed again, and according to their own statement, unnecessary connections are to be reduced. Whether this will be implemented remains to be seen. The Steam client remains under observation.

Originalanalyse
https://steamcommunity.com/sharedfiles/filedetails/?id=3608562371
Nach dem jüngsten Update des Steam-Clients zeigt die Analyse der Netzwerkverbindungen, dass ein erheblicher Teil der Infrastruktur nun über verschiedene Google-Dienste abgewickelt wird. In den aktiven Verbindungen erscheinen neuerdings Komponenten wie Google Optimization, Google Safe Browsing, Google Accounts und Google Autofill.

Funktionsbeschreibung
Die Anfragen dienen soweit ersichtlich dem Nachladen technischer Modelle und Sicherheitsdaten. Die Google-Kontoabfrage überprüft, ob ein Konto im lokalen Profil hinterlegt ist, ohne Kontoinformationen zu übertragen. Die Autofill-Dienste laden Modellkonfigurationen, die zur Erkennung von Formularfeldern dienen. Der Optimization Guide bezieht Modellinformationen für Leistungs- und Interface-Optimierungen. Safe Browsing aktualisiert die lokalen Gefährdungslisten.

Übertragene Daten
IP-Adresse, Zeitstempel, TLS-Daten, User-Agent, Accept-Language, Accept-Encoding, Origin, Host, Connection, Content-Type, Content-Length, gpsia, source, json, X-Client-Data, key/API-Key, Protobuf-Nutzlast, X-Goog-Encode-Response-If-Executable, X-Goog-Api-Key, Sec-Fetch-Site, Sec-Fetch-Mode, Sec-Fetch-Dest, Request-URL, Query-Parameter, X-HTTP-Method-Override, Safe-Browsing-Listen-IDs, Safe-Browsing-Versionsstände, Safe-Browsing-Hash-Range-Informationen, Safe-Browsing-Deltaupdate-Anforderung.

Zusätzliche Google-Infrastruktur
steamcloud-ugc.storage.googleapis.com
redirector.gvt1.com
r4---sn-4g5ednks.gvt1.com

"UGC" steht für "User-Generated-Content", kurz, Dinge die Anwender hochladen, landet in der Google-Cloud.

Die *.gvt Domains gehören ebenfalls zur Google-Infrastruktur. Sie verteilen verschiedene Inhalte wie Update-Pakete, Erweiterungen, Mediendateien und auch Werbevideos auf zahlreichen Plattformen.

Chrome-Einstellungen im Steam Client
Einige Einstellungen können in Steam geändert/angepasst werden, zum Beispiel unter

chrome://flags/ für experimentelle Einstellungen wie WebRTC-Lecks, Overlays
chrome://settings/ für Datenschutzeinstellungen, Cookies
chrome://history/ euer Browserverlauf in Steam
chrome://device-log/ Log von allen angeschlossenen oder getrennten Geräten

Leider nicht das grundlegende Verhalten...

Edit 1: Valve-Stellungnahme - 20. November 2025
https://steamcommunity.com/sharedfiles/filedetails/?id=3609251822
Ein Mitarbeiter von Valve hat sich im Thread von lightwo geäußert. Das Verhalten wird erneut geprüft, und nach eigener Aussage sollen unnötige Verbindungen reduziert werden. Ob dies umgesetzt wird, ist offen. Der Steam-Client bleibt weiterhin unter Beobachtung.

Some of you may be familiar with the VueScan scanner software from home use. A review of the software has been published on https://gameindustry.eu/reviews/vuescan/

Please note that this is not a Steam review, but in the usual quality. Together with the corresponding host entries.

The review for "The Quarry" by 2K has been updated today, as a lot has changed since the initial review and most of the criticized connections and product mechanics have become obsolete.

The link is available through the curation page of the updated products or directly at https://steamcommunity.com/id/pen-chan/recommended/1577120

The connection overview on the project page has also been updated. Host details will follow in the next update.

Since users are also restricted by geo-blocking within group curation, here is the current review of Horny Villa. Alternatively, on the project page with additional information.

Da Anwender selbst innerhalb der Gruppenkuration mit Geoblockaden gegängelt werden, hier das aktuelle Review zu Horny Villa. Wahlweise auf der Projektseite mit weiteren Informationen.

A new group announcement has been written, but it seems to be blocked by the system *sigh*

Well, a new update for the filter lists has been released on GitHub and the project page. The reason for this was a hotfix for a Google address that was causing videos on YoutTube to play for only one minute.

Regarding Ace. The plan is to test more games with this service (there aren't many anyway, apart from that), as well as to collect and publish the addresses involved. But I won't be able to say much or anything about the raw-data it contains. Not obvious to me. Well, it won't happen until next year anyway.
ペンギン Dec 5, 2024 @ 11:19pm 
The issue in this topic by many users has always been (as I mentioned in the linked article) the connection to the CCP. Those who fear them must also be wary of American products that employ similar control mechanisms for surveillance, political control, factory compromised hardware as well as unsolicited data collection.

Feel free to discuss the Anti-Cheat topic in this group, contribute any information and continue asking questions. However, I kindly ask that the discussions remains factual, as there is often a lack of reliable sources and especially, evidence in the public consensus. Much of it could only be proven by insiders.
