I’m trying to take a look at a scamming website, but it’s using the debugger spamming to make reverse engineering difficult. Is there a way to just disable the debugger keyword? I don’t really like to give the websites control over whatever I want to view.
Did you find a way to do it?
The last time I ran into this problem I did manage to find a way to disable the debugger spam, but I don’t remember how I did it.
Someone made a build that replaces it here: https://github.com/Sec-ant/anti-anti-debugging-debugger-firefox
There is also a userscript but I haven’t tested how well it works: https://greasyfork.org/en/scripts/440060-anti-anti-debugger
Some searches of the addon store come up with similar anti debugger extensions, again not tested.
I used the greasymonkey script with tampermonkey without any modification. And it seems like that script magically worked even though the code doesn’t look like it applies to all of the cases. Thanks, this helped a lot.
Update: After further testing, the script doesn’t really help a lot, because it broke all the JavaScript used on that website all together, which explains why the debugger stopped spamming. Disabling all the JavaScript is not what I want; I want to be able to use the browser tools to trace certain functions.
Could get a plugin to disable JS on that page until you source and disable the code
would it help to curl down the source html and scripts? I’m no professional at dealing with malicious code, but i would definitely recommend doing it inside a clean VM or docker container or something
curl the source down works, but it makes things more complicated. The source code is obfuscated making it incredibly hard to read. This is where using the web debugging tools shine. If I want to figure out which code is trigger what, I can just look at the call stack. I also wanted to look at the internet traffic to see how things work from there. I could intercept all the HTTP requests but that wouldn’t give things like the call stack. I think it would be much easier if there’s a way stopping the debugger spamming trick.
Try the icon next to the cog, right hand, middle of the screen. It should disable all breakpoints
That icon did skip over the debugger keyword, but it didn’t solve my issue because it still prevented me from viewing that website’s source. Now the websites just becomes super laggy. I’m assuming that there’s a forever loop that does nothing running in the background now that the debugger keyword constantly gets skipped over.
Can there be a solution where I can replace debugger to something that can cause the thread to sleep for like half a second?
