Overview
Dictionary attacks are much faster than simple brute force attacks because they focus on the most likely passwords. Attackers often use 'wordlists' containing millions of common passwords, names, and dictionary words.
Effectiveness
These attacks are highly effective because many people use simple, easy-to-remember passwords. Attackers also use variations (e.g., replacing 's' with '5') to increase their chances of success.
Prevention
- Strong, Unique Passwords: Avoiding common words and phrases.
- Salting and Hashing: Protecting stored passwords from being easily cracked.
- Rate Limiting: Limiting the number of login attempts from a single IP.
