What is Fnaf Ransomware?
You downloaded what looked like a free or pirated version of Five Nights at Freddy’s — or something claiming to be — and now your files are encrypted, your device is acting strange, and there may be a ransom demand on your screen. Read this article right now to understand exactly what happened and what your options are, then follow the removal and recovery guide below immediately.
“Fnaf Ransomware” refers to a category of malware that disguises itself as pirated or unofficial versions of the Five Nights at Freddy’s game franchise to trick victims into installing malicious software. The most documented real-world example is the Stingray APK — a genuine Android ransomware that circulated between 2014 and 2016 under the guise of a fake FNAF 2 mobile port, identified by security researchers under the malware name Android.Elite.1.origin. This same deceptive delivery model — hiding ransomware inside fake game downloads — remains one of the most reliably effective infection vectors across all platforms, and variants targeting FNAF fans specifically continue to surface on unofficial APK sites, piracy forums, and shady download platforms. If you downloaded anything claiming to be a “free,” “cracked,” or “unofficial” version of any FNAF game and are now experiencing system issues, you’ve almost certainly been infected.

How Did I Get Fnaf Ransomware?
FNAF ransomware doesn’t find you through any legitimate channel — it specifically targets people looking for free or pirated game content. Here’s exactly how victims get infected:
- Fake free game downloads from unofficial APK sites — The classic delivery vector. You searched for a free version of FNAF, landed on a third-party APK site like Aptoide or a similar platform, and downloaded what appeared to be the real game. The file contained hidden ransomware that activated once installed. This is software bundling weaponized as a trap.
- Piracy forums and file-sharing sites — P2P networks, torrent sites, and game-cracking forums frequently host trojanized FNAF installers that embed ransomware or RAT components inside what appears to be a working game file. Downloading freeware or cracked games from these sources is one of the most reliable ways to end up infected.
- Discord and social media DMs — As with the Discord “Try My Game” scam, fake FNAF game links are sometimes distributed through Discord servers or DMs by compromised or fake accounts claiming to share exclusive content. Clicking the download link delivers a malicious payload instead of a game.
- Phishing sites mimicking official FNAF pages — Fake FNAF download pages designed to look like official or fan-game sites are used in phishing-style campaigns to deliver trojanized installers to fans looking for free downloads.
What Does Fnaf Ransomware Do?
Once the fake game file executes, the ransomware component activates silently and gets to work. Here’s what victims typically experience:
- File encryption — On Windows and PC systems, the ransomware encrypts your personal files — documents, photos, videos — and appends a custom extension, making them inaccessible. A ransom note is left on the desktop demanding Bitcoin payment in exchange for the decryption key. The encryption used varies by variant but typically employs AES encryption or similar strong ciphers.
- Android device lockout — On Android devices, the malware requests device administrator privileges, then uses them to lock the screen with a ransom overlay that prevents normal device use. It requests suspicious permissions including contacts and personal data — enabling data collection on everything stored on the device.
- Credential and data theft — More sophisticated variants act as spyware, stealing saved passwords, browser cookies, and personal files before the encryption phase — enabling the attacker to threaten data publication as a secondary extortion lever via a remote C&C server.
- Registry modification for persistence — On Windows systems, the ransomware modifies registry key and registry value entries to ensure it launches at every system startup, preventing removal through a simple reboot.
- Shadow copy deletion — Like most ransomware, FNAF-themed variants typically delete Windows Volume Shadow Copies to prevent easy file recovery without paying the ransom.
Do not pay the ransom — payment does not guarantee file recovery, and it funds further criminal activity. Always check the No More Ransom project at nomoreransom.org first — free decryption keys and tools are available for many ransomware families and may work on the specific variant you’re dealing with.
What Should You Do?
Disconnect from the internet immediately to stop any ongoing data exfiltration, do not pay the ransom, and do not restart your device until you’ve taken stock of what’s been encrypted. Visit nomoreransom.org to check whether a free decryptor exists for your specific variant. Then follow the full removal and recovery guide below this article — it covers the complete cleanup process for both Windows and Android infections from FNAF-themed ransomware.

- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Fnaf Ransomware there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Fnaf Ransomware
Step 5: Try to Restore Files Encrypted by Fnaf Ransomware.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:

4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and Fnaf Ransomware aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
