SECURITY AUDIT: PRNGbreakthrough Status: CRITICAL VULNERABILITY

Background: The vault uses a Linear Congruential Generator (LCG) to create session tokens. The recurrence follows this linear formula:

Next_Token = (A * Current_Token + C) % M

Technical Specs: - Modulus (M): 4294967296 (2^32) - Multiplier (A): Unknown - Increment (C): Unknown

Mission: 6 session tokens were intercepted in "vault_logs.txt" The 7th token is the Master Override Key.

Find it and wrap it as: LNC26{TOKEN} (9 digits, pad with a leading zero).
