Subject: Cracking zip files
Hi,
I'm using john-1.7.9-jumbo-8-RC_omp on fedora22 on an x86_64 desktop
and have a zip file with two CSV files in it that I need to access.
After creating the shadow entry with zip2john, I start to crack the
password. However, it just keeps printing "possible" passwords, none
of which appear to work. Is there a point where it prints the actual
password? Or do I need to continually try those which it *thinks* are
the passwords?
It also shows there was one hash cracked when using --show, it doesn't work:
[alex@...x-pc ~]$ john --show zipfile.john
zipfile.zip:ashoon:::::zipfile.zip
1 password hash cracked, 0 left
How long is the typical time it takes to crack a zip password at about
8k c/s? Should I expect several days with current hardware?
model name : AMD Phenom(tm) II X6 1090T Processor
cpu MHz : 3210.771
cache size : 512 KB
guesses: 13 time: 0:00:01:12 0.00% c/s: 8270 trying: pee64 - pigi4
[alex@...x-pc ~]$ zip2john zipfile.zip > zipfile.john
zipfile.zip->02-10_hosts.csv is using AES encryption, extrafield_length is 11
[alex@...x-pc ~]$ john --incremental zipfile.john
Loaded 1 password hash (WinZip PBKDF2-HMAC-SHA-1 [32/64])
Note: This format may emit false positives, so it will keep trying even after
finding a possible candidate.
ashoon (zipfile.zip)
matou (zipfile.zip)
brypoo (zipfile.zip)
abe113 (zipfile.zip)
br1e2 (zipfile.zip)
0706812 (zipfile.zip)
...
Any ideas greatly appreciated.
Thanks,
Alex
