Reports have surfaced that popular image-sharing website – Imgur has been hacked with malicious code injected in its images to carry out DDoS attacks on 4chan and its smaller spin-off, 8chan. Both image boards have suffered downtime.
The attack was first publicized when Reddit user ‘rt4nyp’ discovered a traffic-based DDoS attack on popular imageboards 4chan and 8chan.

After being notified of the vulnerability, Imgur fixed the same quickly afterwards. In a blog post, the company said:
“From our team’s analysis, it appears the exploit was targeted specifically to users of 4chan and 8chan via images shared to a specific sub-Reddit on Reddit.com using Imgur’s image hosting and sharing tools. The affected images were not published to the galleries on Imgur.com.”
“The vulnerability was patched yesterday evening,” Imgur confirmed.
Reddit users who have accessed the 4chan sub-Reddit are advised to clear their browser’s cache. The same applies to wiping browser data and removing saved cookies immediately.
