In April 2026, we discovered a new campaign targeting users of hentai games. Attackers are embedding a remote access Trojan named Argamal into game installers. While concealing its presence, it can remotely control the computer and steal files and personal data.<\/p>\n

Here\u2019s how to avoid falling victim to this new Trojan\u00a0\u2014 and how to safely and anonymously enjoy spicy content with (or without) anime girls.<\/p>\n

How computers get infected with Argamal<\/h2>\n

Most of the infected games are distributed through adult game and torrent sites. In some cases, they are posted for download on file-sharing services and linked on gaming websites.<\/p>\n

\"Trojanized<\/a>

Interestingly, instead of finding a dummy file inside the archive\u00a0\u2014 as is often the case\u00a0\u2014 the user gets the actual game built on popular engines like RenPy or RPG Maker. Infected pirated versions usually turn out to be scams: games fail to launch, folders are full of files with bizarre extensions, making it rather easy to put two and two together. Here, however, the user gets the actual gameplay they expected. Meanwhile, the Trojan lets itself in and keeps a completely low profile.<\/p>\n

\"Malicious<\/a>

Tucked right alongside the legitimate files in the archive is a DLL that the game relies on to run, but it\u2019s been rigged: as soon as the user launches the game, the infected DLL automatically loads into memory. There are no outward signs of infection: neither an installer popping up in the background, nor a scary window or prompt asking you to disable your antivirus.<\/p>\n

Argamal takes things real slow: instead of immediately rushing to steal files and passwords or throwing a digital rager on your computer<\/span>, the Trojan first checks whether it\u2019s running in a virtual machine or sandbox, and then goes into standby mode.<\/p>\n

During this time, the malware writes hidden parameters to the system, conceals the paths to its DLLs, and delays its own execution. Three days later, the computer connects to GitHub, downloads an encrypted file, decrypts it, and turns it into a working Trojan module.<\/p>\n

To ensure persistence, the attackers register the malware under the WindowsColorSystem Calibration Loader<\/em> system task, a built-in Windows feature that triggers at every user logon to load monitor color profiles. Before shutting down, the malware deletes temporary files and covers its tracks to make it even harder to detect.<\/p>\n

What makes Argamal dangerous?<\/h2>\n

Argamal is a remote access Trojan (RAT), which means attackers can use it to remotely control the victim\u2019s computer. Here\u2019s just a short list of what it may entail:<\/p>\n
