Bug in SHA512 (Unix) Hashcat? - MuMMeL - 07-25-2012 10:22 PM
Hello everyone
My Problem ist the Attack of this Hash Value (Ubuntu 12.04)
oh-lala:$6$zv8dHfXf$HFYc5i.i9NcutOUKniZpkhIx9XkW8qo61XdXJZxpZXjtkV9MmPi9owX9ib1VNt5E1M88MCt4UovX7bHNlYQUw/
The Password Structure is unknown and the User "oh-lala" died last Week.
My loooong Dictionary Attack was useless.
PasswordsPro said the Password is "4rfvbgt5" but it is wrong.
I install a Ubuntu 12.04 in a virtual Maschine and setup a Test User
tester:$6$n.x8pyjJ$y/9YEn.7e3TrjfAmbvVK89rE9u5YlUBJyqWambc6wH4oAbk.ooVn4W8yEQijadbVgKLG9omTmVJBzX.CtMLTa1
The Password is "12345"
i tried a short Dictionary with "12345" inside and Hashcat cant find it?
A Bruteforce Attack was also unsuccessful.
The Hashcat Settings:
hashcat-cli32.exe --hash-mode 1800 --attack-mode 3 c:\Path\testershadow.txt ?d?d?d?d?d
Is everything wrong or I've misunderstood something?
Use Ubuntu a different kind of Hash?
I love Hashcat
Sorry for my really bad English
Best regards
MuMMeL
