The fastest Windows password cracker

[brooklyn]

A Windows password cracker based on the faster time-memory trade-off using rainbow tables. This is an evolution of the original Ophcrack 1.0 developed at EPFL. Ophrack 2.2 comes with a GTK+ Graphical User Interface and runs on Windows as well as on Linux.

I really dont think you should be posting this on here as i have a feeling it may be breaking rule #1

1. This is not a warez site! Links/Requests to warez and/or illegal material (porn, cracks, serials, etc..) will not be tolerated. Discussion of circumventing WGA/activation/timebombs/keygens or any other illegal activity will also not be tolerated. You will be banned without notice.

Hmmm I tend to agree.

[Camarade_Tux]

Not necessarily : "technology news". I think it's pretty interesting.

This is not warez, maybe hacking but not warez. Moreover you need a physical access to the computer and I don't know if it is able to retrieve passwords from a domain-controller or anything similar.

In a way, this is a tech tool...

I used OphCrack a few times because I didn't have full access to a computer I had to repair.

I also used this tool to make sure our Local Admin Password is strong enought and cannot be retrieved using this "easy" tool

it maybe fit in crack category but how can you catch a thief when you cant think like a thief.

by the way thanks brooklyn,ive just used lopht crack before but im gonna test this one out.

This is perfectly allowable. We have discussed ways of recovering Windows passwords or even resetting them in the past.

nice tool . work fine on my home computer.

i had need once for a friend... now i will keep it.

[Aegis]

Only disadvantage is that it requires a huge lookup table (7GB for passwords with symbols such as @ % #).

I just use Trinity rescue kit 3.1

Hacking is not a bad thing. Hacking is an actual profession of modifying programs in a beneficial way. Cracking is what you got to watch out for, because cracking is Criminal Hacking.

that's not even related. that's for resetting passwords, which is easy as cake.

this topic is about recovering passwords not resetting them.

Hum, I have to thank you.

I stumbled on ophcrack/l0phtcrack last week and thanks to you I tried it.

It found the weak password I use to get my windows installations in no time (with livecd, under a VM : >2 min).

And in ten minutes everything included, it found the admin password at my school. It was not a sophisticated one, a short one in fact but it worked. ^^

Hopefully, they weren't using a complicated pass (*^¨$£¤%...) because otherwise it would not have worked (this part costs >1000€).

Btw, I fixed one computer. And am probably going to install Flash Player on some computers because it seems the tech is nonexistant....

Anyway,

Pretty much nailed it. Nobody use the Windows Password unless fooling a small minded child or joe from the office. The only reason I use it is that my computer demanded it for filesharing on LAN. I had to open a few computers up since the password thing would block the folders.

Sometimes I would gamble that Windows would not find a file and allow me to browse for them myself.
