wcostream.tv getting past the adblock detector

Post by joshex » 2026-08-03, 02:56

so, I have no problems with this in FF51.0 (old firefox), but in palemoon even enabling tons of ads in nmatrix it still ends up replacing the video with the anti-adblock response...

the only errors given are:

Code: Select all

None of the “sha384” hashes in the integrity attribute match the content of the subresource. 
video-js-old.php
TypeError: document.body is null[Learn More]  
ad_728.js:4:1

I'm looking for a work around.

edit: I went through thier sourcecode to determine what they were looking for to determine if ads were being blocked. they were checking fdor several specific ad vendors making sure they could reach given urls. unblocking those XHRs in nmatrix while leaving the rest of the ads disabled worked.

I guess that site's owners really really really wanted you to view those specific ads!!

For me, that would be one site I simply would not visit, as I don't like having to lower a lot of shields in eMatrix. But those live TV sites tend to be like that.

Glad you were able to figure it out.
