Mythos and the cost of attacking
For twenty years, cybersecurity defense rested on a simple idea: make attacking so expensive that adversaries give up and move on. Cheap, capable AI breaks those economics. Recon, exploit development, phishing, and command-and-control infrastructure now run at model speed and cent-per-million-tokens cost. The detect-and-respond doctrine struggles when an attacker’s OODA loop compresses from weeks to seconds. The prevention bar has to rise from blocking known-bad to predicting intent from behavior.
