Collaborate Disseminate
I’m pentesting for a class in Kali Linux, cracking a Windows 7 password. I mounted the windows’ hard drive in Kali, ran PWDUMP7 and got the hashes saved on the desktop. It’s only showing some of the users, but not any that I created for te… Continue reading John the Ripper Brute Force not working (Windows Hash)
We have a situation where I am not finding any documentation on it. We are trying to scale across multiple machines/job by breaking up the keyspace by complexity. Its a 7 char completely random alphanum pwd.

I am going to use John the Ripper on a multi-core server to crack about 400 Windows NT hashes. Depending on my CPU capacities I want to check all passwords that satisfy following masks:
?1?1?1?1?1?1?1 –min-len=1
?2?2?2?2?2… Continue reading John the ripper multiple mask attack
We’re doing a password audit by loading the password file into John and letting it run for a couple of days.

I ran Responder in a test network and obtained hashes from a Windows machine. The logs for the machine show something like this (some bytes changed for security reasons) and are stored in a file called “SMB-NTLMv2-SSP-192.168… Continue reading Cant crack Responder hashes with John or Hashcat

–incremental=Digits
–devices=all
–fork=3
–format=Blockchain-opencl
–session=s1
when I restore the the work with named sesion it shows:
./john --restore:s1
Loaded 1 password hash (blockchain-opencl, blockchain My Wallet [PBKDF2-SHA1 OpenCL AES])

I have 2 GPUs (Tahiti) and one CPU. Unfortunately I run this with –fork=3 option. One GPU session has ended, second GPU should also end, I do not know it for sure from this message. Is there any chance to reassign the rest of the work from CPU to GPUs?
I have tried to modify the sesion.rec file and then restore the session but without correct result.
