Full Analysis
  • [COMMAND_EXECUTION]: The scripts/agent.py script performs forensic analysis by executing Windows utilities like wevtutil, reg, and powershell via subprocess.run. These calls use fixed argument lists to query system state and logs.
  • [INDIRECT_PROMPT_INJECTION]: The skill possesses an attack surface for indirect prompt injection as it processes untrusted data from external sources.
  • Ingestion points: Reads content from Windows Event Logs (.evtx files) and the Windows Registry using scripts/agent.py.
  • Boundary markers: The script does not utilize explicit delimiters or 'ignore' instructions when outputting snippets of the ingested data.
  • Capability inventory: The script has the capability to execute shell commands (subprocess.run) and perform file system operations.
  • Sanitization: The script performs regex-based filtering to identify specific patterns and outputs results in a structured JSON format, but does not perform escaping on the logged data itself before presentation.
  • [METADATA_POISONING]: The SKILL.md file contains instructions to bypass antivirus warnings, labeling them as false positives. While this is a common malware technique, in the specific context of a security skill documenting malware signatures, it aligns with standard practice for handling signature-triggering research materials.
Recommendations
  • CRITICAL: 1 infected file(s) detected - DO NOT USE
  • CRITICAL: 1 file(s) identified as malware by FileRep - DO NOT USE
