Anime site Crunchyroll Down and hacked to spread malware

Couple of days ago, it was revealed that the popular anime website Crunchyroll was down while getting hijacked by hackers that used it to distribute malware to the visitors under the guise that the virus was a desktop streaming application. A statement was issued on the website for visitors to stay away from it until the issue gets taken care of. At the moment of writing, it seems that things are back to normal and there’s no longer malware getting distributed through Crunchyroll.

Crunchyroll Viewer download prompt

While the attack was still ongoing, visitors to Crunchyroll were getting greeted by a pop-up download suggestion that promoted what seemed like a desktop steaming application named Crunchyroll Viewer for the site. However, it was eventually discovered that the recommended download had malicious code inside of it. It is still unknown what the exact purpose of the malware is. Some researches have stated that it might be a keylogger virus. If we come across more precise information regarding the purpose of the malware, we will make sure to update this article with whatever new we learn. So far, we do not know the number of users that have fallen for the misleading download suggestion.

Crunchyroll was down but it didn’t get hacked

According to a statement made by the people behind Crunchyroll, their site didn’t actually get hacked but rather became a victim of a DMS hijacking. Apparently, the hackers have been able to obtain access to the Crunchyroll’s Cloudflare account allowing them to redirect the site’s traffic to another address – a separate website controlled by the cyber-criminals where the malware-distributing download pop-up was displayed to the visitors.

The good news is that if any of our readers have mistakenly downloaded the Crunchyroll Viewer malware from the Crunchyroll site while the DMS hijack attack lasted, we might be able to help you remove the malicious code from your PC so that it won’t be able to do any harm to you.
