I have not seen evidence that Mythos (or GPT-5.5 Cyber) are revolutionary. Still: these models are getting better at tools and at chaining lower-severity bugs into access, persistence, and real damage.
Anthropic and OpenAI try to block malicious use. Two things stay true:
- They do not always succeed
- Less-scrutinised labs are not far behind
So ASIC's recommendations land for financial institutions - and for everyone else:
- Know critical assets and systems
- Patch fast; fix the process that makes patching slow
- Test incident response under pressure, not only on paper
The Five Eyes agencies later said the same timeline in sharper words - months, not years. Your risk register should already assume faster exploit development.
