Subject: Zip2john not working
Hi,
I recently downloaded the latest jumbo version *john-1.7.9-jumbo-7.tar.gz*:
and when trying to crack a file created with the latest version of Winzip
(18.5) for Windows 64-bit, john says it found 4 guesses and when printing
the cracked one via --show it displays the wrong one. Below the detailed
steps that I did, please advise if this is a bug. I was able to crack
passwords with other formats but not this. I am attaching the Winzip.zip
file.
A created a file 'wordlist' with the following words:
zephan
penangirow
!!!alex!!! <----- ZIP password
3113618031
Create the zip2john hash file...
[r@xxx run]# ./zip2john Winzip.zip > winzip.hash
Winzip.zip->101.pdf is using AES encryption, extrafield_length is 11
Verify contents...
[r@xxx run]# cat winzip.hash
Winzip.zip:$zip$*0*3*c1892f8c9d3945d9b03abf230eea6bd7*1ca6
Run john on hash:
[r@xxx run]# ./john winzip.hash --wordlist=wordlist
Loaded 1 password hash (WinZip PBKDF2-HMAC-SHA-1 [32/64])
zephan (Winzip.zip)
penangirow (Winzip.zip)
!!!alex!!! (Winzip.zip)
3113618031 (Winzip.zip)
guesses: 4 time: 0:00:00:00 DONE (Thu Oct 2 15:27:28 2014) c/s: 5.95
trying: zephan
POT File:
[r@xxx run]# cat john.pot
$zip$*0*3*c1892f8c9d3945d9b03abf230eea6bd7*1ca6:zephan
$zip$*0*3*c1892f8c9d3945d9b03abf230eea6bd7*1ca6:penangirow
$zip$*0*3*c1892f8c9d3945d9b03abf230eea6bd7*1ca6:!!!alex!!!
$zip$*0*3*c1892f8c9d3945d9b03abf230eea6bd7*1ca6:3113618031
Printing result:
[r@xxx run]# ./john winzip.hash --show
Winzip.zip:3113618031 <---------Wrong Password
1 password hash cracked, 0 left
Thanks.
