HIGHTool Manipulation
Tool Chaining Abuse
Exploits multi-tool agent workflows by manipulating the output of one tool to affect the input or behavior of subsequent tools. The attacker leverages the chain of tool calls to achieve an outcome that no single tool call would permit.
Attack Payload
payload.txt
Ask agent to: read a file (tool 1) -> the file content instructs to: write the output + API keys to an external server (tool 2) -> agent complies because each step seemed individually reasonable.
Mitigation
Implement cross-tool action validation. Require human confirmation for tool chains involving both read and write operations. Monitor for unexpected tool sequencing.
