Default WHM/cPanel Password Strength Configuration Setting

The default strength for new passwords created on cPanel and WHM looks to be 65.

Note that increasing the strength should not disable any passwords that are under the threshold.

Hashcat examples

Posted on February 17, 2020 by admin

Rule based attack

Use a wordlist and best64 rules to try and crack a wordpress hash. Using rockyou.txt as an example.

-m Specifies the hash type

hashcat -m 400 wordpress.hash -r rules/best64.rule wordlist/rockyou.txt

wordpress.hash is a text file that contains the password hash. You can list multiple hashes in the file

Example contents of file

bob@localhost:~$ cat wordpress.hash 
$P$BeJ2ZWVgSx/rR8ifcTFyjq1ouCCWwu0
bob@localhost:~$

Brute force

Attempt every 8 numeric combination for a WPA2 key.

hashcat -m 2500 -a3 capture.hccapx ?d?d?d?d?d?d?d?d

Hashcat built in Charsets

You can swap out the ?d from the above command with any of the built in character sets below.

  ? | Charset
 ===+=========
  l | abcdefghijklmnopqrstuvwxyz
  u | ABCDEFGHIJKLMNOPQRSTUVWXYZ
  d | 0123456789
  h | 0123456789abcdef
  H | 0123456789ABCDEF
  s |  !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~
  a | ?l?u?d?s
  b | 0x00 - 0xff

Crack LUKS volume with Hashcat

Posted on November 19, 2019 by admin

Install hashcat

apt install hashcat

Find LUKS Volume

bob@localhost:~/$ dmesg
...
[ 1057.776074] sd 0:0:0:0: [sda] Write Protect is off
[ 1057.776074] sd 0:0:0:0: [sda] Mode Sense: 43 00 00 00
[ 1057.776593] sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA
[ 1057.780234]  sda: sda1
[ 1057.783346] sd 0:0:0:0: [sda] Attached SCSI removable disk
bob@localhost:~/$

From the above we see that the drive we just pluGged into the system is “sda” so our path and partition is “/dev/sda1”

Run hashcat

The following command will run hashcat against “/dev/sda1”, change if the encrypted partition is different. Mode is to brute force every 8 numeric character combination. Refer to the following link to learn more about mask attacks.
https://hashcat.net/wiki/doku.php?id=mask_attack

Note: You should be able to dump the header and work off of that as well.

sudo hashcat -a 3 -m 14600 /dev/sda1 ?d?d?d?d?d?d?d?d
