Predictability & Patterns: While wordlists typically run sequentially, research shows that humans choosing 6-digit PINs (often used as static OTPs or backups) frequently pick predictable patterns like 123456, 111111, or dates (DDMMYY). Security researchers often use "top 10" or "top 100" subsets of these wordlists to crack accounts faster, as 20% of all PINs can often be cracked with just a few attempts.
Attackers will keep refining their wordlists. Tomorrow’s lists might include:
