I would think you could probably write a script to substitute 1 letter at a time in the sequence for every other letter in the alphabet, and dump any which return a hit into a text file before continuing. similar to a 4-digit combo lock, just scroll until it opens. it's bruteforcing essentially, but a computer would do it much faster. might be a good idea to throw in a proxy switcher so the attack is less conspicuous in the server logs.

I don't know the first thing about actually scripting though.

There's either 6^10 = 60466176 or 10^6 = 1000000 (I'm pretty sure it's this one but cbf to confirm) possible combinations. I forgot which. That being if it's only letters ranging from q to z and they're fixed at a 6 character length. Assuming you can made 3 requests a second (Potentially using a ton of proxies, and don't get banned/blocked along the ay) it will take you respectively 233 days or 4 days straight of attempts. Good luck!

Fail on above math. it's 10^10

if you want a list of all possible combinations let me know. it's 6.6MB

can't tell if trolling or... but no.

the number of combinations when order matters is
b^n
where b is the base and n is the number of digits. so with a base of 26 (a..z) and six digits that makes 26^6 combinations
