Lesson 1: Password Strength & Brute-Forcing

Hacker computers guess passwords using speed and automation. In this training, you will secure systems sequentially.

MISSION PROGRESS: 1 / 3 (The Length Proof)

Targeting: Student Locker

Length: 0 chars
Keyspace Pool: 0
Estimated Crack Time
-
Audit Rating
-

Entropy Indicators:

  • ❌ Lowercase Letters (a-z)
  • ❌ Uppercase Letters (A-Z)
  • ❌ Numbers (0-9)
  • ❌ Symbols (e.g. ! @ # $)

Mission 1: The Length Proof

Prove how length multiplies entropy. Secure the three client computers sequentially:

1. Student Locker
6+ chars, crack time over 1 second
LOCKED
2. Library PC
8+ chars, 2+ types, crack time over 1 hour
WAITING
3. School Email
10+ chars, 2+ types, crack time over 1 day
WAITING

Mission 2: Pattern Banishment

Hacker tools check dictionaries and pattern rules. Secure administrative databases:

1. Teacher Portal
10+ chars, 3+ types, no repeated characters
LOCKED
2. Admin Database
12+ chars, 3+ types, no sequences (e.g. '123'/'abc')
WAITING
3. Firewall Host
12+ chars, 3+ types, no dictionary words
WAITING

Mission 3: The Passphrase Vault

Passphrases chain simple words, creating massive length that is easy for humans but impossible for brute force. Secure the vaults:

1. School Core Vault
3+ words, hyphen-separated, length >= 16
LOCKED
2. Backups Backup Server
4+ words, hyphen-separated, length >= 22
WAITING
