These settings are easy to overlook.\\”\\n\\n\\n\\nThe attack is made possible because of agent discovery and agent-to-agent collaboration capabilities within ServiceNow’s Now Assist. With Now Assist offering the ability to automate functions such as help-desk operations, the scenario opens the door to possible security risks.\\n\\nFor instance, a benign agent can parse specially crafted prompts embedded into content it’s allowed access to and recruit a more potent agent to read or change records, copy sensitive data, or send emails, even when built-in prompt injection protections are enabled. \\n\\nThe most significant aspect of this attack is that the actions unfold behind the scenes, unbeknownst to the victim organization. At its core, the cross-agent communication is enabled by controllable configuration settings, including the default LLM to use, tool setup options, and channel-specific defaults where the agents are deployed -\\n\\n * The underlying large language model (LLM) must support agent discovery (both Azure OpenAI LLM and Now LLM, which is the default choice, support the feature)\\n * Now Assist agents are automatically grouped into the same team by default to invoke each other \\n * An agent is marked as being discoverable by default when published\\n\\n\\n\\nWhile these defaults can be useful to facilitate communication between agents, the architecture can be susceptible to prompt injections when an agent whose main task is to read data that’s not inserted by the user invoking the agent.\\n\\n\\”Through second-order prompt injection, an attacker can redirect a benign task assigned to an innocuous agent into something far more harmful by employing the utility and functionality of other agents on its team,\\” AppOmni said.\\n\\n\\n\\n\\”Critically, Now Assist agents run with the privilege of the user who started the interaction unless otherwise configured, and not the privilege of the user who created the malicious prompt and inserted it into a field.\\”\\n\\nFollowing responsible disclosure, ServiceNow said the behavior is intended to be this way, but the company has since updated its documentation to provide more clarity on the matter. The findings demonstrate the need for strengthening AI agent protection, as enterprises increasingly incorporate AI capabilities into their workflows.\\n\\nTo mitigate such prompt injection threats, it’s advised to configure supervised execution mode for privileged agents, disable the autonomous override property (\\”sn_aia.enable_usecase_tool_execution_mode_override\\”), segment agent duties by team, and monitor AI agents for suspicious behavior.\\n\\n\\”If organizations using Now Assist’s AI agents aren’t closely examining their configurations, they’re likely already at risk,\\” Costello added.\\n\\nFound this article interesting?
