s1r1us, one of the white hat hackers who recently breached OpenAI, clarified that finding one serious exploit doesn't mean knowing how to secure such a complex organization, and that OpenAI has far more experienced security staff. He confirmed current models already have serious offensive cyber capabilities. Nathan Calvin added that frontier labs claim world-historic, potentially catastrophic stakes yet run security practices comparable to a random game or B2B SaaS company—sometimes worse—and that employees' concerns appear sincere and increasingly justified.
