I can Crack Any Microsoft Key In Less Than 10 Hours :o) You Can Do That To ,

All you need is KNOWLEDGE and a computer system/hardware worth around 4.000 USD :o)

Those guys at Microsoft are really DUMB for having ALL THAT technology in their hands and yet producing a TERRIBLE kind of piracy protection in their software.

So thats why they began SPYING on your pc files DAILY so that their SPAMING TECHNIQUES could find out if you are LEGIT or NOT.

Isnt this HACKING into MY computer ?

IF I DO THAT IN THEIR COMPUTERS WONT THEY PROSECUTE ME ?

I l just say that i was trying to find/see if THEY USE legit software as well !!!

The judge will have to buy that ,cause MICROSOFT is doing the SAME THING IN OUR COMPUTERS 100 TIMES A DAY-DAILY !!!!

THIS IS HACKING , WHAT THEY DO

GET BACK TO THEM

Surely it would still be illegal.

That’s one impressive napkin!

This is a naive and slow brute force attack using a vbscript to randomly test keys against the local logic.

Doing a quick back of the napkin calc:
The keyspace is somewhere around 25^25 (probably a bit smaller, because there are probably some rules about checksum and number of consecutive chars).
The bruteforce is reported to be very slow, testing about 1000 keys per hour.
Even with a high number of ‘valid’ keys (say, sqrt(keyspace)), we’re talking cold sun before the probability of finding a single valid key goes above 50%. Roughly 17 bill years if my napkin is correct.

And any keys found will only pass the local test, there is no guarantee that they will pass the more stringent WGA.

Some people have claimed that the bruteforce has found valid keys, but none of them have been posted. Occam’s razor would suggest that they are just making fun of the true believers.

For this to work, someone has to do an optimized version of the local key validation logic and set up a distributed system a’la distributed.net.

I believe, as an expert, this “dude” would expect a much more efficient program. As a coder myself, I can assure you that there are most likely hundreds of lines of code in that Keygen that could be condensed.

Thanks for that, and the ‘cunning’ choice of words, ‘dude’.

What a strange response:

>there really isn’t much intelligence involved and the goal is to just randomly cycle through key after key after key until a legit one is found

What is the Microsoft dude hanging out for someone to come up with an elegant keygen?
