If you are running services and don't yet have an easy way to react to these things with swift process defined, I hope you don't like to sleep.
I dont think my security posture is all that much different than it was last year. Use a Secret Manager and or encryption, have backups, strong firewall rules, use canaries of some kind.
If anything llms are making security worse because there's more people offloading their thinking on llms, or people that skipped some steps in their learning journey because they just ask the llm to do everything. I dont think its necessarily because attackers have llms now, but that contributes.
Edit:
Damn Im getting mega downvoted for saying this. So are people of just at a consensus that there's nothing you can do? That we're in security armagedon???
Have you ever thought to consider that security took hit along with the general degradation of software because of AI??
To speak to your edit: this is false equivalency. You can still decrease the odds of being hit. There are still better and worse ways to address security.
