Black hat actors exploit DeepSeek harness plugins, sparking security debate

A post highlights the security risks of the DeepSeek harness plugin system, noting that black hat actors have already begun exploiting it. The discussion emphasizes that a verified plugin list is necessary and that the harness itself should be immutable for end-users in production, restricting mutability only to developers. The author warns that the permissions currently granted to the harness are excessive and need restriction. This points to emerging business opportunities in agent plugin security.
