Understanding Dictionary Attacks

Word Lists

Attackers compile lists of common passwords, words from dictionaries, names, places, and leaked password databases containing millions of entries.

Transformations

Common substitutions like E-3, A-@, O-0 are applied. Attackers also try capitalization patterns, appending numbers, and leetspeak variants.

Hybrid Attacks

Combining dictionary words with brute force (e.g., "password" + all 4-digit numbers) dramatically reduces search space for common patterns.
