As you may be aware there has been an issue today with Crunchyroll, who appear to have been the target of a DNS Hack. Whilst Crunchyroll’s social media accounts are now reporting that normal service has been restored, if you accessed the site via your computer or the Crunchyoll app today you may find that a malware file named CrunchyViewer.exe has been downloaded. As this file contains harmful Malware it should not be opened and should be removed as soon as possible. If you have opened the file then you will likely want to use a site such as https://www.bitdefender.co.uk/ which offers free antivirus and scanning services to help remove the malware.
We should note that whilst Crunchyroll have not yet issued a formal statement and it has not been confirmed whether any personal information has been accessed you may wish to change your password even if you have not downloaded the file in question.
We will of course keep you advised of any new developments.
Update: 05/11/17: Crunchyroll have now made an official statement on their blog (https://blog.ellation.com/crunchyroll-com-update-a2a593cf9155), and have now confirmed that there was no access to their servers and customer data has NOT been compromised. They also provide full details on how to deal with the malware if you have downloaded or accessed the malware file.
