Full Analysis
  • [PRIVILEGE_ESCALATION]: The skill's setup instructions include sudo apt-get install commands for installing tools like nmap, netcat, hydra, and smtp-user-enum in SKILL.md. Executing these commands grants the agent administrative privileges to modify the system environment.\n- [COMMAND_EXECUTION]: The skill defines various workflows that involve executing powerful command-line tools such as nmap, hydra, nc, dig, nslookup, and openssl to interact with network services and perform security assessments.\n- [INDIRECT_PROMPT_INJECTION]:\n
  • Ingestion points: The skill instructs the agent to read and parse banners and response codes from external SMTP servers via tools like nc, telnet, and nmap as described in the banner grabbing and enumeration phases of SKILL.md.\n
  • Boundary markers: There are no specific instructions or delimiters provided to prevent the agent from being influenced by potentially malicious strings returned by a target server.\n
  • Capability inventory: The skill enables the agent to perform network scans, DNS lookups, and authentication brute-forcing based on findings from the ingested data.\n
  • Sanitization: No logic is provided to sanitize or validate server responses before they are processed by the agent.
