Charles Hoskinson said IOG's YouTube channel had been compromised and urged users not to trust videos or follow links on the platform. He said the team was working with YouTube to remove the channel and reset credentials. The warning follows a Sept. 18 apparent takeover that hosted a suspected AI-manipulated Cardano giveaway livestream styled as a Project Catalyst town hall, using apparent Hoskinson footage and a QR code that promised to double users' crypto. At the time of the latest warning, the channel still displayed recent legitimate-looking IOG uploads and IOG's X account had not posted about the alleged compromise. The episode underscores how hijacked accounts can be used to distribute phishing links and fraudulent giveaways.
