A recent security investigation details Argamal, a Windows remote access trojan distributed through trojanized adult-game downloads. The practical risk is not the game category itself, but the archive workflow: a user follows a download link, receives a ZIP package, runs the game, and a modified library chain quietly drops a RAT that can give attackers remote control.
The campaign is worth treating as a post-download cleanup issue. Securelist ties the delivery path to redirects through PixelDrain, torrent listings on AniRena, a modified ffmpeg.dll, a dropped natives2_blob.bin payload, PowerShell execution, and persistence through a Windows COM hijack path. If you downloaded one of these archives, do not keep testing it to see whether the game runs.
Who Should Check Their PC
Check your Windows system if you recently downloaded an adult game, game cheat, patch, or archive from a torrent page, file-hosting redirect, forum mirror, or unofficial catalog and then saw one of these signs:
- a ZIP archive that required extra unpacking, a password, or a launcher outside the expected game folder;
ffmpeg.dllor other media libraries appearing in a suspicious game directory;natives2_blob.bin, unknown PowerShell activity, or files dropped under public or temporary Windows paths;- new autorun behavior, strange outbound connections, or security alerts naming Argamal or a generic Trojan/RAT family;
- browser, gaming, Discord, email, or payment sessions behaving strangely after the game was executed.
What Argamal Changes On Windows
| Evidence from the report | Why it matters |
|---|---|
| PixelDrain redirects and AniRena torrent listings | The infection begins in the download path, so deleting only the visible launcher may leave the real payload behind. |
Modified ffmpeg.dll |
A familiar library name can make the package look normal while it loads malicious code. |
natives2_blob.bin and PowerShell activity |
The second-stage payload can be staged after the game appears to run, which makes quick manual inspection unreliable. |
| COM persistence through Windows Color System Calibration Loader | The RAT may survive reboot through Windows component hijacking rather than a simple Startup shortcut. |
| Remote access trojan behavior | Once active, the attacker can control the system, inspect files, steal sessions, and prepare follow-on malware. |
What To Do After Running A Suspicious Archive
- Disconnect the PC from the network if you see active unknown processes, repeated PowerShell windows, or outbound-connection alerts.
- Delete the original game ZIP, extracted folder, launcher, and any related torrent/download manager task. Do not run the archive again.
- Check the game folder for
ffmpeg.dll,natives2_blob.bin, unusual DLLs, scripts, or recently changed files. - Review Startup folders, Task Scheduler, Run keys, and COM-related persistence if you are comfortable doing so. If not, use a full antimalware scan instead of editing the registry manually.
- Run a full Windows security scan, then use Gridinsoft Anti-Malware as a second-opinion cleanup check for RAT remnants and suspicious persistence.
- From a clean device, rotate passwords for gaming, Discord, email, browser-sync, cloud storage, crypto, and payment accounts used on the infected PC.
- End active sessions where the service allows it. Password rotation alone is weaker if a stolen cookie or token remains valid.

FAQ
Is Argamal only a problem for adult-game downloads?
The current investigation focuses on adult-game lures, but the defensive lesson is broader: unofficial game archives, cheats, and repacks can carry payloads that look like normal game files.
Does deleting the game remove Argamal?
Not necessarily. The report describes a staged payload and persistence behavior, so the right response is to remove the archive, scan the system, check persistence, and rotate accounts if the file was executed.
Should I change passwords after an Argamal infection?
Yes, if the suspicious archive was run. Treat it as a remote-access and session-risk incident, especially for accounts used in the browser on the same Windows profile.
