Users of Anthropic Claude and OpenAI Codex reported that the services began blocking attempts to use the AI for reverse engineering and decompiling software. In some cases accounts were suspended, and projects that modify users' own devices were also affected.
According to 404 Media, several Claude Code users experienced security mechanisms that prevented reverse engineering, and a Reddit post in the Reverse Engineer Anything community announced that the “dream is dead”. Discord participants confirmed that the services now refuse to decompile programs.
