Validin MISP Integration & YARA Improvements

Validin is available as a MISP expansion module to enrich MISP events across Validin’s DNS, host responses, registration, certificates, and subdomain data sources, with both enrichment and hover modes. Validin also expanded YARA hunts to include IPv4 scanning (over 50 ports), which uncovered exposed Telegram bot tokens and exposed bot servers on ports 8082 and 8083. #Validin #Telegram

Keypoints

Validin released a MISP expansion module (single Python file) in the misp-modules repository to enrich MISP attributes like domain, hostname, ip-src, and ip-dst.
Validin enrichment covers multiple data sources with lookbacks: DNS (14 days), Host Responses (21 days), Registration (30 days, enterprise), Certificates, and Subdomains.
The module supports two entry points: Enrichment Mode (add/propose enriched attributes to events) and Hover Mode (immediate contextual hover information).
YARA scanning in Validin now includes active IPv4 host response data in addition to virtual host data, increasing scanned port coverage from ports 80/443 to 50+ security-relevant ports.
Using YARA, Validin’s team and users detected exposed Telegram bot tokens via a regex rule and discovered exposed Telegram bot servers on nonstandard ports (e.g., 8082, 8083).
The integration and YARA capabilities improve CTI workflows by enabling richer enrichment and broader hunts; documentation and the open PR are available for review in the misp-modules repo.
