Malware-Laden Game Removed from Steam: What Gamers Need to Know

Valve recently took swift action to remove PirateFi, a game that was discovered to contain malware specifically designed to steal sensitive data from gamers. The game, which had garnered attention on Steam, turned out to be a Trojan horse built to distribute the Vidar infostealer, a notorious piece of malware that has been linked to numerous cybercriminal activities.

A Trojan Horse Masquerading as a Game

PirateFi wasn’t just a game that was compromised after release—it was intentionally built to deceive players. According to security researchers, the game was created using a tool called Easy Survival RPG, a game-building template that allows developers to rapidly launch their own games. This template, which costs between $399 and $1,099, gave the attackers an easy way to embed malicious software into what appeared to be a legitimate game.

Marius Genheimer, a researcher with the SECUINFRA Falcon Team, confirmed that the malware wasn’t a secondary feature. PirateFi was designed solely as a vehicle for distributing Vidar malware. “It is highly likely that it never was a legitimate, running game that was altered after first publication,” Genheimer explained. In other words, PirateFi was simply bait for unsuspecting players.

The Dangers of Vidar Malware

Vidar is a sophisticated infostealer that can extract a wide range of personal information from infected systems. Once installed, it can steal saved passwords, hijack accounts, capture screenshots, and even access cryptocurrency wallets. What makes Vidar particularly dangerous is its ability to steal two-factor authentication codes and session cookies, allowing cybercriminals to bypass even extra security layers.

Vidar has been linked to several major cybercrimes, including targeted attacks on hotel booking credentials and widespread ransomware campaigns. Its reach has only expanded since its discovery in 2018, earning it a reputation as one of the most effective infostealers in the wild.

The Rise of Malware-as-a-Service

One of the most troubling aspects of this attack is the rise of malware-as-a-service. Vidar is readily available for purchase by cybercriminals of all skill levels, which makes it difficult to trace the specific individuals or groups responsible for attacks like PirateFi. As a result, the perpetrators behind this attack remain anonymous.

Researchers found multiple samples of the malware embedded in PirateFi, confirming that the game was specifically designed to distribute Vidar. One sample was uploaded to VirusTotal by a gamer in Russia, while others were found through SteamDB and in threat intelligence databases. These samples all exhibited identical functionality, further proving the intent behind the game.

Steam’s Swift Response and Ongoing Concerns

Valve acted quickly to remove PirateFi from Steam after discovering the malware. While the company has not commented publicly on the incident, its rapid response suggests that it is actively monitoring its platform for malicious content. However, the fact that PirateFi made it onto Steam in the first place raises concerns about the potential for future attacks.

Adding to the mystery, the developers of PirateFi, listed as Seaworth Interactive, have no real online presence. The game’s official X (formerly Twitter) account was deleted shortly after PirateFi was removed from Steam, and the account’s links led directly to the game’s Steam page. Attempts to contact the developers for comment have gone unanswered.

A Warning to Gamers: Stay Vigilant

This incident serves as a stark reminder of the growing cybersecurity risks facing gamers. While Steam is generally a safe platform, it is not immune to cybercriminals who exploit its large user base. To protect themselves, gamers should remain cautious when downloading lesser-known titles, keep their systems up to date with the latest security patches, and enable multi-factor authentication to safeguard their accounts from potential breaches.

The rise of malware-as-a-service platforms and the increasing sophistication of cyberattacks suggest that incidents like this could become more common. Awareness and vigilance remain the best defense against these types of threats.

Protecting Yourself in a Digital World

As gaming continues to evolve, so too do the tactics of cybercriminals. While platforms like Steam offer a wide range of entertainment, they also serve as prime targets for malicious actors. This incident with PirateFi should be a wake-up call for all gamers to stay informed and proactive about their digital security.
