Cracking Spectrum WiFi Passwords

Learn how to build a wordlist and use Hashcat to crack default Spectrum WiFi passwords.

---

Step 1: Understand the Target and Pattern

Default Spectrum WiFi passwords follow a specific pattern.

The target password pattern is: [adjective][noun][ddd]
Example: happydog422

Spectrum passwords are lowercase and consist of:

• 6-character adjective
• 4-character noun
• 3-digit number

We will generate a wordlist that combines adjectives, nouns, and three-digit numbers.

Step 2: Generate Your Wordlist Using Hashcat --stdout

Hashcat's --stdout mode allows you to build the wordlist by combining multiple files._

Activity: Generate the Wordlist

1. Prepare your input files:

   • adjectives.txt: Contains all possible adjectives (e.g., happy, smart, tiny).
   • nouns.txt: Contains all possible nouns (e.g., dog, bird, fish).
   • numbers.txt: Contains all three-digit numbers from 000 to 999.

2. Combine adjectives and nouns to create a combined_wordlist.txt:

   hashcat --stdout adjectives.txt nouns.txt > combined_wordlist.txt
   

3. Add three-digit numbers to complete the wordlist:

   hashcat --stdout -a 1 combined_wordlist.txt numbers.txt > final_wordlist.txt

How to Protect Your Spectrum Wifi from Password Cracking

To reduce the risk of your WiFi network being compromised, follow these steps:

• Change your default WiFi network name (SSID): Default names like "MySpectrumWiFi" reveal the router type, making it easier for attackers to target you. Use a custom SSID instead.
• Set a strong, unique WiFi password: Use a long passphrase with a mix of uppercase letters, lowercase letters, numbers, and symbols.
• Avoid dictionary words or easily guessed combinations. Example: N3tw0rk!Secure#2025
