VSCode not showing malicious PHP code. #83576
Comments
|
@FernandoGarcia The code is rendered, but the first line has a lot of space characters, so you need to scroll to the right to see it. I believe this is done intentionally by the malware authors to make it more difficult to spot the code:

Hi! Thanks for your time! I know about large white space because I found in other files. I think the rendering has changed because in others files I did see the code on minimap while searching as you saw after toggle word wrap. Maybe another detail that has contributed for this issue is because the cursor was not moved to match place as should be. Here an example.
The reason is: The line is not entirely rendered ending with 3 dots.
Best regards |

I agree that the cursor was not revealed (when the column was > 10000). I have recently fixed that with #50304 and the fix is already available in the insiders release channel -- https://code.visualstudio.com/insiders/ The fact that we don't paint over 10k characters is tracked in #7772 |

This problem can be used to difficult the malicious code to be found because the author can add over 10k white space on start. |
Hi!
I have some malicious PHP code in a file and the editor is not showing it.
I can see the code only using the search tool on editor as you can see in image below.
Opening the code in text editor I can see:
