From 55dcdd1164240671e74794bfc2fcf1971dc1f23a Mon Sep 17 00:00:00 2001 From: egutierrez Date: Thu, 30 Apr 2026 16:24:11 +0200 Subject: [PATCH 1/9] feat(cybersecurity): 8 IoC regex extractors + extract_iocs pipeline puro Extractores nuevos en python/functions/cybersecurity/: - extract_ip_addresses (IPv4 + IPv6 con validacion ipaddress) - extract_emails (RFC 5322 simplificado) - extract_domains (FQDNs con TLD valido, lista estatica) - extract_file_hashes (MD5/SHA1/SHA256/SHA512, algoritmo por longitud) - extract_crypto_wallets (BTC legacy + bech32, ETH 0x+40hex) - extract_cve_ids (CVE-YYYY-NNNN+) - extract_mac_addresses (xx:xx:xx + xx-xx-xx, separador uniforme) - extract_phone_numbers (E.164 + ES local 9 digitos) Pipeline: - extract_iocs corre todos, deduplica spans contenidos. Mantiene purity:pure (kind:function con uses_functions no vacio) porque la regla del registry exige que los pipelines sean impuros. Todas devuelven list[dict] con value/start/end/type para que el caller (issues 0038-0040) pueda reconciliar offsets con spans NER sin reparsing.
