1080p: Because all software is written bug free and scales to more than a million members in a few days with no problems at all. I would have expected someone with your perspective to understand teething problems with new software better than most.


The quote above is not from gzt

And now others are quoting your shocking misquote!! Gah!! Please be more careful about using quote tags next time !!!

Edit: All sorted. Thanks for the apology sonyxperiageek, and big thanks to the mods for fixing up the attributions on the previous page.

sonyxperiageek: Maybe you could try MegaCracker as posted by me above?


um.. I tried it by double clicking the .exe but I get a missing .dll error.

Looking at the readme file makes me think I should be doing something with a DOS command line, but I don't understand the conventions he's using.

So I'm downloading something from the Internet that I don't really understand, from someone I don't know, and run it on my PC. To fix a problem caused entirely by my own stupidity.

Yee-yah let's do it!

Oh no, this was on the MEGA blog talking about cryptography.. here is the link again - https://mega.co.nz/#blog_3

I'm just about there. The dll thing was solved by downloading c++ from MS.
Here is the README file:I have copied the confirmation link to notepad and know how to copy it into the command line using alt/space, edit, paste.

I've been trying varieties of  [the path] megacracker -h <[the copied link]>

but I always get a message saying "The syntax of the command is incorrect" or "Error '-h' requires a value", "Error: missing argument -h|--hash, -H|--hash-file, or -o|--output"

Can someone advise what I should type?

Here is the README file:

**** MegaCracker v0.1a ****

Cracks a Mega password from a confirmation link. Do NOT post your confirmation
link because it contains not only a hash of your password but your encrypted
master key. Once the master key is disclosed all your file can be decrypted.

./megacracker-64 [options]

-h|--hash=<string>
Confirmation link.

-H|--hash-file=<file>
File with confirmation links.

--help
Display help and exit.

-i|--input=<file>
File with passwords to test [default is stdin].

-I|--input-precomp=<file>
File with pregenerated data.

-o|--output=<file>
Output data to use later.

---------------


There are at least six things in the confirmation link:
* Encrypted master key (16 bytes)
* Password hash (16 bytes)
* Unknown field (15 bytes?)
* Email address
* Name
* Unknown field (8 bytes?)


This will extract the password hash and crack it.
This will except confirmation links in these forms (You can truncate the data after #confirm to 43 characters):
* https://mega.co.nz/#confirm...........................................
* mega.co.nz/#confirm...........................................
* #confirm...........................................
* ...........................................


If you want to generate some you can run this in your web browser's console:
var pw_aes = new sjcl.cipher.aes(prepare_key_pw("password"));
base64urlencode(
a32_to_str(
encrypt_key(pw_aes, [rand(0x100000000),rand(0x100000000),rand(0x100000000),rand(0x100000000)]))+
a32_to_str(
encrypt_key(pw_aes, [rand(0x100000000),0,0,rand(0x100000000)])));
dqKqDkwkeaJZCSm8gOUTRsgil2fSec1H4J0i2Z8aIbg


This is a precomputed list of passwords. You can use this with -I|--input-precomp:

I just typed in megacracker -h --hash (then immediately followed by the confirmation link string with no spaces between "--hash" and "confirmation link".

Now just tells me that my cpu can run 64 instead of the 32 bit code I'm currently running... not sure what next.

I just tried megacracker -h [confirmation link]. It appears to be doing something. I'm using a very old (expendable!) 333mhz pentium 2 running xp. Task manager- processes is showing megacracker using 908k memory and 0% CPU. But if I sort by CPU usage it is 4th - above cmd, notepad, and others.

The C:\ prompt hasn't come back but the cursor has.

So maybe it is working. I wonder how long I should leave it?

It seems you have to use -i to provide an input file that contains all the passwords you want the program to test against the contents of the confirmation link.

That's not any use to me, as I can just try my guesses on the log in page.

I think megacracker is more aimed at hackers who have a big file of 1000s of common passwords that would be too boring to try one by one.

Hah!
Just tried uploading a file this morning - it worked!
Pretty quick too....

Signed up on day one and NEVER got anything to upload until today - it just used to sit there staring at me.

Logged in today to find out all the files there weren't there yesterday are now showing up. Not only that but most files are actually duplicated - in one case there are three folders with the same name and four copies of the same file in the same folder.

Is that because you tried uploading the files/folders more than once?

Also, there is a setting in the My Account section that lets you choose whether you want duplicate files or not.

Yesterday none of the files uploaded appeared in the list so I uploaded the same file multiple times. That's what happens when the UX and UI don't work ;)

Talking about account settings, none of the changes I made yesterday are there (upload speed, SSL use, etc).

It seems the load balancing could have caused sync problems in their database?
