GhostSecure v2.1.2 — Thread Safety & Reliability Fixes

What's Fixed

• Race condition in Golden Ticket detector — write to _tgt_issuance dict was outside _tgt_lock; now protected by lock on all reads and writes
• SMTP connection leak — connection stayed open on exception before quit(); replaced with with smtplib.SMTP(...) as server: context manager
• Detection loop blocked by email thread — email thread was joined with timeout=30, blocking detection for 30s per alert; now fire-and-forget daemon thread
• Version header inconsistency — 6 module headers still said GhostSecure 2.0; all updated to 2.1
• Added .gitignore — excludes __pycache__, logs, DB files, and credential file patterns

v2.1

Windows service that monitors Active Directory in real time and alerts on 8 live attack techniques — Kerberoasting, Pass-the-Hash, DCSync, Golden Ticket, LDAP Recon, AS-REP Roasting, Skeleton Key, and Audit Log tampering. Built in Python using Windows Security Event Log analysis.
