A Reddit user has uncovered a covert method of carrying DDOS attacks on 4chan's infrastructure using images hosted on Imgur, via Reddit.
According to Reddit user rt4nyp, who discovered the vulnerability, every time an Imgur image was loaded on the /r/4chan sub-reddit, over 500 other images were also loaded in the background, images hosted on 4chan's CDN.
Since traffic on 4chan is quite huge as is, getting some extra connections from Reddit pushed 4chan's servers over the edge, crashing them several times during the day. Additionally, 8chan, a smaller 4chan spin-off, was also affected and suffered some downtime as well.
