1. Information
>What is happening?
Our admin is testing new ad services on the homepage, related pages and archived threads. Some users reported redirects to malicious websites.
>Facts
- The ads in question are served from hxxp://ecpmrocks.com, which allows injecting its own Javascript and is able to redirect and hijack browsers. The script tries to read HTML5 localstorage cookies. The official ad host is Epom Market LTD.
- Traditional ads are served by hxxp://zkcdn.net, which only serves images.
>Unconfirmed rumors
- ECPM may be a legit ad hosting service. However, a simple Google search leads to questionable results, since hackers can inject and distribute malicious scripts.
- Board ads may be infected. The distributor is not injecting scripts, it should be harmless.
- Infected downloads are happening.
>Current Situation
Servers are sometimes changing; the frontpage may serve ads from hxxp://bnhtml.com. Said ads are still running scripts.
2. Prevention/Security
>Browsers/Extensions
- For enhanced security, it's generally recommended to use a browser that supports extensions. Examples include: Firefox, Chrome.

KEEP ME POSTED
That reminds me malware adbro
What the fuck is zkcdn.net and how have I not noticed it for a whole year now? People first started seeing it last February in NoScript apparently.
I know it has "something" to do with an advertiser called Adzerk, but I don't know what its connection is with the whole malware thing.
Is there any?
>>466891
I think I'm just going to start blocking ads on 4chan.
Hiro clearly isnt looking out for us, so we dont need to bother looking out for him.

>not blocking ads everywhere all the time
I can't stand that people still do this and prop up the failed 1990s clickthrough business model.

For the longest time 4chan has had not terrible ads. It wasn't until the chinese menace came that advertisements started giving malware.

its just a rumor bro its just a rumor

No. "Malware" ads are only present in the front page and in the archives. "Malware" because they aren't really malwares, they are just redirectors.
>not having your Adblock on all the time in the age of malvertising.
Shiggy diggy
Bump frum train.
Why hasn't anyone really made a big deal about this? It's a pretty big change, and having a video front and centre every time I visit an archive link seems far more intrusive than what I've come to expect
Was there a shitstorm I missed or something?
How do I get these ads to show up?
