Mirage2FA DNS query with Base64-encoded email subdomain on kit domains
Detects DNS queries for suspicious subdomains on known Mirage2FA phishing kit domains ('cheacker.store' and 'volatilesour.store'). The rule identifies queries where the subdomain is Base64-encoded and decodes into an email-like format, which is a technique used by this phishing kit to track or validate victim-specific session tokens or email addresses.
