Help with cracking md5
#1
Hi everyone, I'm new to the forums and to hashcat in general so forgive me if I ask any silly questions.

So basically I'm just trying to experiment a bit on my own and created a hash for hashcat to crack. Let's say the password is arsenal123 and I know that the password starts with arsenal but I don't know the rest of the numbers/letters. How can I input the arsenal portion of the password so that Hashcat doesn't have to go through those letters trying to crack it? I only want it to crack the last 3 characters of the password.

Thanks everybody

I feel like looking into this mask attack would be the right direction. Am I right?

Edit: In this case I don't want to put variables for each letter though. I know the specific letter. The wiki doesn't tell me how to replace each character with a static letter

Correct, your getting there so keep reading.

Damn I've got it. Sorry guys. Believe it or not I actually read most of the wiki articles before posting this. I just wasn't looking close enough.

Apologies again

Sorry guys I need a bit more help. The password is heygoaway so i typed cudahashcat64.exe -a 3 -m 0 hash.txt heygoa?l?l?l but it keeps coming up as exhausted. I know for a fact that the password is correct and I pulled the hash straight from Cain and Abel

does your md5 hash end with this? 5268999
#9
No. Does this mean the hash from Cain and Abel is wrong?
#10
yes, hash the password yourself and retry.
