To protect systems from being compromised by numeric wordlist attacks, organizations must implement robust defensive controls:
The table below illustrates estimated time requirements to exhaust an entire 8-digit numerical keyspace across different algorithms and consumer hardware setups: Algorithm Type Hash Example Average Speed (Mid-Range GPU) Estimated Exhaustion Time Legacy databases 15–20 Billion Hashes/sec < 0.01 Seconds NTLM Windows Active Directory 20–30 Billion Hashes/sec < 0.01 Seconds WPA2 (PBKDF2) Wi-Fi Handshakes 500,000 Hashes/sec ~ 3.3 Minutes Bcrypt ($2b$05) Modern web applications 20,000 Hashes/sec ~ 1.3 Hours
Attacks against websites are often limited by rate-limiting (e.g., maximum 5 guesses per second).
You can create a small list of these common patterns and attempt them before running the full brute force. 8 Digit Password Wordlist
If you are an administrator or a user, how do you protect yourself from the reality that 8-digit wordlists are trivial to brute force?
: Using crunch to generate every single combination. This ensures coverage but results in a file size of approximately 900 MB for plain text 8-digit numbers.
A network software suite consisting of a detector, packet sniffer, and WPA/WPA2 cracker, frequently paired with 8-digit lists to test network handshakes. Risks and Vulnerabilities of 8-Digit Passwords To protect systems from being compromised by numeric
Commonly used for cracking WPA2 Wi-Fi handshakes or PIN codes. Since it only contains 100 million lines, the file size is relatively small (about 900MB in a standard .txt format), making it easy to store and run. 2. The "Commonly Used" List
: Helping administrators identify users with weak, numeric-only passwords. Specops Software Security Vulnerabilities
: When storing numerical credentials, utilize slow, salted hashing functions like Argon2id or Bcrypt with high work factors to explicitly limit the computation speeds of offline attacking arrays. : Using crunch to generate every single combination
The command to crack a hash using an 8‑digit numeric mask attack is:
Auditing default router handshakes requires testing the complete 8-digit range. Tools feed this numerical list into capture files to see if a factory-set key was left unchanged by the consumer. 2. PIN Brute-Forcing
Wordlists should only be used on systems you own or have explicit, written permission to test. Using these tools to access unauthorized accounts is illegal and unethical.
