Jeuxvideo connexion bloquer, Faux positif ? Ou comment faire confiance ?

Embuscade

Bonsoir

Au fond, je ne sais pas et je n'en sais rien, mais dans le doute bitdefender à réagis la pluspart des fois ou j'ai essayer de me lancer dans une partie multijoueurs sur ce jeuxvideo [*url removed by @Flexx *] Airmech au quel je me suis relis dernièrement.

The connection to 139.162.156.119 has been blocked to protect you. Your device is safe." tel my antivirus.La connexion à 139.162.143.128La connexion à 45.79.138.218La connexion à 45.79.129.225

Et il me dise de le permettre ? Cependant moi, je ne sais rien de tous ça, j'ai entendu dire qu'il y avait de plus en plus de faux jeux ajoutés sur steam avec des virus et autres choses, j'en suis limite à ne plus faire confiance à des communautés de opensource multijoeurs qui modifier des paramètres dans le jeu, et offre des packages à télécharger..

Je veux dire, comment avoir confiance ?
- Si vous avez un guide pour savoir à quel momment je dois donner ma confiance ou non, il n'y as pas des certificats pour ça ? Vais-je devoir attendre mars 2028 l'annonce de google qui renforce la sécurités ?

What AirMech Actually Is:

AirMech is an established multiplayer online strategy game developed by Carbon Games, available on Steam and known since 2012. It is not a random or suspicious program; rather, it has a legitimate presence on Steam with mostly positive reviews and a long-standing history as an action‑RTS multiplayer game. From a reputation standpoint, the game itself is generally considered trustworthy and legitimate.

Why Bitdefender Is Blocking Those Connections:

When you launch the game and Bitdefender displays a message like “Connection to 139.162.156.119 has been blocked… Your device is safe,” it means your antivirus or firewall is blocking network traffic based on IP reputation and threat detection, not necessarily because the game is malware. Bitdefender’s network protection monitors outgoing and incoming connections and may block anything it considers potentially malicious or risky.

There are several common reasons for these alerts. First, the game may be trying to connect to multiple servers or peers. Many online games connect to several IP addresses, including central game servers, peer hosts, or third-party networking hosts. Bitdefender cannot always identify what each IP represents, so it may block connections that appear suspicious. Second, false positives are quite common. Security software sometimes flags safe connections incorrectly, particularly for games using custom servers or peer-to-peer matchmaking. Bitdefender allows users to add trusted IPs to exceptions if they feel confident about the source. Third, antivirus reputation lists can be overprotective. IP reputation is complex and often crowd-sourced, meaning an IP that was once flagged as risky can remain on multiple blocklists even if it is no longer harmful. For this reason, many cybersecurity tools let users create trusted exceptions for known safe connections.

Should You Allow the Blocked Connections:

Whether you should allow the blocked connections depends on the trustworthiness of the source. If the game comes from Steam or an official website, and you downloaded it directly from the corporate site or your Steam library, the game itself is not a virus—it is a legitimate game played by many people worldwide. However, IP addresses by themselves are not certificates; they are simply numbers that can belong to game servers, cloud hosts, or even malicious servers. Allowing connections without knowing their origin could put your system at risk if those IPs are compromised. The best practice is to only allow connections when you are certain which servers they belong to—ideally information confirmed by the game developer. If you are unsure, do not allow them immediately.

How to Decide What’s Safe:

To decide what is safe, you can follow these practical steps. First, check where you downloaded the game. A Steam version is generally safe from a malware perspective, and the official Carbon Games website is also considered legitimate. However, random Discord links or unofficial builds are not guaranteed to be safe, so it is always best to prefer official sources. Second, read reviews and community information. AirMech is a long-standing title with very positive reviews and a solid track record over many years. Third, scan the game files. You can upload executable files, such as the game’s .exe, to tools like VirusTotal to see if multiple antivirus engines flag them. One or two flags might be false positives, but numerous flags could indicate a real risk. Finally, configure your antivirus properly. If you trust the game, you can allow the game executable through Bitdefender’s firewall and add known safe IPs to the exception list. You should not allow connections blindly—only after confirming that they are related to the game or its official servers.

About Certificates and Trust:

Certificates are primarily used for websites and software signing, serving to confirm that the game publisher or website is who they claim to be. However, games and online IP connections do not inherently come with certificates. While game servers may use certificates for HTTPS connections if they are browser-based, multiplayer servers using UDP or TCP typically do not. As a result, there is no universal certificate for all game servers—this is simply a limitation of how networking protocols work.

Bitdefender Tips:

Here are some general Bitdefender tips. You can add exceptions for specific IPs or programs that you trust. Bitdefender’s firewall also allows you to categorize network zones as trusted or untrusted. If you receive repeated alerts for the same IP but are confident it belongs to the game, you should only add that IP to exceptions after verifying that it is not malicious.
