LLM might be faster at password bruteforcing at al
AI agents can use automation tools and are not limited to being chat bots. LLM just gives dumbasses like you and me the ability to communicate with them.
An AI agent could triage vast libraries of vulnerable targets, designate server resources to facilitate multiple attack types in tandem, and effect cyber warfare on a scale that would require 100s, possibly 1000s, of human agents.
AI could develop innovative malware that simultaneously causes harm and obfuscates it's presence. It could coordinate DDOS attacks etc against rival cyber security assets. Attack power stations.
I am far from the only person concerned about this. https://gizmodo.com/get-ready-the-ai-hacks-are-coming-2000639625
