AI Tools Are Generating Massive Attacks for Little Cost

darkreading

A recent report reveals that attackers are using AI tools to launch large-scale cyberattacks at a very low cost. One notable campaign targeted 105 websites, employing open-weight models to gain unauthorized access. In another instance, attackers managed to gain full control over a domain for merely $12 using publicly available AI models. This shift in tactics suggests that cyber-defense strategies need to evolve rapidly, as the cost-effectiveness of these AI-driven attacks makes them more accessible to a wider range of adversaries. As organizations increasingly rely on digital platforms, they must bolster their security measures against these emerging threats.
