CST VerdictBased on our analysis of available product data, here is our conclusion:
Incident responders and malware analysts who need to quickly triage RTF-based phishing attachments should use RTFSig to extract and fingerprint suspicious structural elements that commodity AV misses. The tool's free, open-source design means zero procurement friction for resource-constrained security teams running limited forensics pipelines. Skip this if you're looking for an automated detection engine; RTFSig is a manual analysis helper that requires operator judgment to interpret signature output, not a fire-and-forget scanning tool.
Incident responders and malware analysts who need to batch-test files against custom detection rules will find Yara File Checker useful for its straightforward library integration and zero licensing friction. The tool wraps YARA pattern matching in a decision layer, letting you automate file assessment without standing up heavy infrastructure. Skip this if you need managed threat hunting or cloud-scale scanning; Yara File Checker is a bare-bones library for teams comfortable writing and maintaining their own rule sets.
