JS/Spy.Agent.AH found - but where?

[mpower 1]

In Chrome and Opera (not in Firefox) the JS/Spy.Agent.AH malware is being found be Eset. The malware was found in https://example.com/checkout/onepage/, so it does not say in which file. How do I know where the malware is hidden? Any advice?

This is how it looks like in the logs:

Thanks!

It should be exactly that page. However, I'm getting 404 "page not found" when trying to download it.

Yeah, Its not the real domain, I changed it :-). Is the malware in a JS file or could it also be PHP?

@Marcos: Sent you a private message 🙂

The website is really infected. In this case, the malicious JS is detected by several AVs, not only by ESET:

Alright, can you give me a hint how to get the infected files?

 

Thanks!

Why in the world would you want to do this?

Are you an administrator of the website?

[mpower 1]

Yes, I am the sites admin (should have mentioned that 😀) and I want to replace the infected files with the none infected version. If I knew the paths to the files(s) it would be no problem ...

I took a code backup and deleted the old code which made it work again.

Thanks for your answers guys

There should be JS reference in your code that is linking to another script from another place where your detection has triggered , or it's hosted in your website which means they can access and upload files to the server

You should secure the server more , so you can make sure that they cannot inject a JS again.

Yeah, I told my customer to change FTP/SSH and database passwords already ...

Thanks!
