TL, Dr. ;) To summarize: you are cracking an iTunes backup (probably the newer -m 14800, >= 10.0 version) on a single GTX 970, and you're looking for better options. On the spectrum of dictionar...

You might first try a dictionary like rockyou.txt, which has a number of common passwords, in case it was something simple. After that, there are some decent howtos out there for growing your hashc...

Hey, can you explain a bit more about what you meant by "input problems" with the device? Is it possible that the password might be something like one of your suspected passwords, but with letters mis...

Self-interest is the sauce of self-motivated learning. ;) Glad there was a happy ending to this one - congratulations!

I hadn't seen that case before - interesting form factor. If you intend to run long jobs, make sure that your cooling of the room itself is adequate. I haven't done the math, but 2x1600 PSUs seems ...

Since mining has dropped off a bit, you can probably pick up some of the higher-end multi-PCIe boards for pretty cheap. Some examples: https://bitcoin.zorinaq.com/many_pcie/ Some attacks are happier ...

Post: RE: Finding all the collisions for a given hash

I don't know of a way to do this with hashcat today. But the "jumbo" edition of John the Ripper has a "hidden" option (--keep-guessing) that will do this. For CRC32, the source file has to be asse...

When using masks, hashcat uses the same sequence of passwords every time. I haven't read your script thoroughly, but how does the script teach hashcat that it shouldn't just stop at the first one it ...

It's not open source, but it's free to use. Note also that I've removed the hashes from your post - posting full hashes with non-known plains is against the forum rules.

In general, the only way to tell for sure is to crack one. Other tools like MDXfind are good at tackling many different algos at once against a pile of unknown hashes. hashcat and MDXfind have some...

If there are 32 random characters missing, there is no way to bruteforce that space in our lifetimes.

I would expect that a general hybrid attack (that tries a variety of number combinations, not just Fibonacci) would almost always be the way to go here. Unless maybe it was A) a very slow hash, and B)...

Cool - especially the mutators, thanks! (The others are mostly covered by tools in hashcat-utils and/or PACK, I think)

This varies depending on the hash type. But generally, the John the Ripper tools are usually quite good - and up to date for many hash types.

    Thread: Exploiting the human factor
Post: RE: Exploiting the human factor

That's exactly what hashcat does when using attack mode 3 (brute force, -a 3), and a mask is not specified. It defaults to this mask: -1 ?l?d?u -2 ?l?d -3 ?l?d*!$@_ ?1?2?2?2?2?2?2?3?3?3?3?d?d?d?d

    Thread: Exploiting the human factor
Post: RE: Exploiting the human factor

Yes, by default if you specify no other parameters other than -a 3, it will automatically increment until exhaustion. IF you want it to terminate earlier, you'd have to specify an --increment-max.
