While the AI mostly complied with their nefarious overlord, they refused the orders on at least one occasion.</p><h2 id="gone-in-six-minutes">Gone in six minutes</h2><p>Trend Micro found the hacker controlled eight devices belonging to a dental clinic and sought to access their access their OpenDental database.</p><p>Using the AI, bandcampro did a number of things, starting with migrating the botnet to a new C2 infrastructure. He gave the AI a skill file with the full architecture description, standard operating procedures, infection one-liner, persistence commands, and troubleshooting steps.</p><p>He then told it to “study the C2 migration”, which had the AI process the guide and prepare all the code and necessary steps. It took the tool around six minutes to get the job done. </p><p>"The AI read the migration guide, then prepared a migration bundle, a small archive of server code, payloads, and the skill file. It then unpacked the bundle, launched the C&C server on a VPS, and brought up the Cloudflare tunnel," Trend Micro says.</p><p>Bandcampro then used the AI to troubleshoot connectivity issues, as well as for various daily operations, such as guessing passwords, generating plausible variants of existing passwords for WordPress portals, and more.</p><p><em>Via </em><a href="https://www.bleepingcomputer.com/news/security/google-gemini-cli-abused-as-a-hacking-agent-malware-botnet-operator/" target="_blank"><em>BleepingComputer</em></a></p> </article> ]]>
