The article discusses how artificial intelligence is transforming the landscape of cyberattacks by making failed attempts cheaper and easier for attackers to retry. A common scenario involves an attacker gaining access to a low-privilege cloud account and attempting to escalate their privileges. In the past, each failed attempt required significant documentation and time, but AI tools now allow for rapid retries without the same overhead. This change could lead to an increase in successful attacks as attackers can quickly learn from their mistakes. The implications are serious for organizations relying on cloud services, as they may face more persistent and adaptive threats. Security teams need to be aware of this evolving tactic and adjust their defenses accordingly.
