Full Analysis
- [EXTERNAL_DOWNLOADS]: The skill's documentation and scripts reference external industry-standard resources, such as the MITRE ATT&CK framework, Sigma detection rules, and the
pyspfPython library for email security validation. These are documented for reference purposes and originate from well-known or trusted sources. - [INDIRECT_PROMPT_INJECTION]: The skill processes external data sources (email logs and endpoint telemetry) to identify threat indicators, which creates a potential surface for indirect prompt injection via malicious log entries.
- Ingestion points:
scripts/agent.py(via the--email-logargument) andscripts/process.py(via the--inputargument). - Boundary markers: No explicit delimiters or boundary markers are used to wrap ingested data during processing.
- Capability inventory: The skill's scripts are restricted to local file system read and write operations for log analysis and report generation.
- Sanitization: Ingested data is evaluated against regular expression patterns to detect indicators; the skill focuses on identification and does not execute the data content.
- [METADATA_POISONING]: There is an inconsistency between the author name listed in
SKILL.md(mahipal) and the copyright holder identified in theLICENSEfile (mukul975). This appears to be a documentation oversight rather than a malicious attempt at deception.
